The '''baht''' ({{IPAc-en|b|ɑː|t}}; {{langx|th|บาท}}, {{IPA|th|bàːt|pron}}; [[currency sign|sign]]: '''฿'''; [[ISO 4217|code]]: '''THB''') is the official [[currency]] of [[Thailand]]. It is divided into 100 ''[[One-satang coin|satang]]'' ({{lang|th|สตางค์}}, {{IPA|th|sà.tāːŋ|pron}}). Prior to [[decimalisation]], the baht was divided into eight ''[[One-fuang coin|fueang]]'' ({{lang|th|เฟื้อง}}, {{IPA|th|fɯá̯ŋ|pron}}), each of eight ''[[One-at coin|at]]'' ({{lang|th|อัฐ}}, {{IPA|th|ʔat̚|pron}}). The issuance of currency is the responsibility of the [[Bank of Thailand]]. [[Society for Worldwide Interbank Financial Telecommunication|SWIFT]] ranked the Thai baht as the 10th-most-frequently used world payment currency as of December 2023.<ref>[https://www.swift.com/file/58686/download?token=4V_STiPJ] {{Webarchive|url=https://web.archive.org/web/20190422163705/https://www.swift.com/file/58686/download?token=4V_STiPJ|date=2019-04-22}}[https://www.swift.com/file/56351/download?token=pg_59sd1 RMB Tracker February 2019] {{Webarchive|url=https://web.archive.org/web/20190422163642/https://www.swift.com/file/56351/download?token=pg_59sd1|date=2019-04-22}}</ref>

The Thai baht, like the [[Pound (currency)|pound]], originated from a traditional unit of [[mass]]. Its currency value was originally expressed as that of [[silver]] of corresponding weight (now defined as 15 grams), and was in use probably as early as the [[Sukhothai Kingdom|Sukhothai]] period in the form of [[Bullet money|bullet coins]] known in Thai as ''[[bullet money|photduang]]''.<ref>{{cite web |title=Thailand Commemorative Bullet Coins (112) |url=https://coincoin.com/I112.htm |website=Scott Semans World Coins |access-date=25 October 2018 |archive-url=https://web.archive.org/web/20171111111216/http://www.coincoin.com/I112.htm |archive-date=11 November 2017 |url-status=dead }}</ref> These were pieces of solid silver cast to various weights corresponding to a [[Thai units of measurement|traditional system of units]] related by simple fractions and multiples, one of which is the ''[[baht (unit)|baht]]''. These are listed in the following table:<ref>{{cite web |url=http://www.chiangmai-chiangrai.com/siamese_money.html |title= The History of Siamese Money |access-date=2018-10-25|date=2010-06-16|website= Welcome to Chiangmai & Chiangrai |archive-url  = https://web.archive.org/web/20110928105132/http://www.chiangmai-chiangrai.com/siamese_money.html |archive-date = September 28, 2011 |url-status= dead |df= mdy-all}}</ref><ref>{{cite web |script-title=th:เหรียญกษาปณ์ของไทย |trans-title=Coins of Thailand |url=http://www1.mod.go.th/heritage/nation/krasab/index1.htm |website=Ministry of Defense of Thailand |access-date=15 October 2011 |language=th |archive-url=https://web.archive.org/web/20120204133229/http://www1.mod.go.th/heritage/nation/krasab/index1.htm |archive-date=2012-02-04 |url-status=dead }}</ref> Though the coins themselves have names like: ''[[One-solot coin|solot]]'', ''[[One-siao coin|siao]]'','' [[One-sik coin|sik]]'', etc, the formal division of the Thai baht (tical) is 1 baht = 8 ''[[One-fuang coin|fueang]]'' = 64 ''[[One-at coin|at]]''. This means that ''one [[One-baht coin|baht]]'' is divided into ''eight [[One-fuang coin|fueang]]'', and each ''one [[One-fuang coin|fueang]]'' is divided into ''8 [[One-at coin|at]]''. Currently, the Thai baht do not employ the ''[[One-at coin|at]]'' as a subunit, but the ''at'' is the current subunit of the [[Lao kip]].

[[File:Siamese Pre-Decimal Tical System.png|thumb|594x594px|Siamese predecimal tical system]]
This predecimal system was in use up until 1897, when the decimal system devised by Prince [[Jayanta Mongkol]], in which one [[One-baht coin|baht]] = 100 [[One-satang coin|satang]], was introduced by his half-brother King [[Chulalongkorn]] along with the demonetization of silver bullet coins on 28 October 1904 after the end of silver bullet coin production by the opening of Sitthikarn Royal Mint in 1857.<ref>{{cite web |script-title=th:เงินตรา |trans-title=Money |url=http://www.royalthaimint.net/ewtadmin/ewt/mint_web/ewt_news.php?nid=46&filename=index |publisher=Royal Thai Mint |access-date=22 November 2020 |language=th |archive-date=4 March 2016 |archive-url=https://web.archive.org/web/20160304103729/http://www.royalthaimint.net/ewtadmin/ewt/mint_web/ewt_news.php?nid=46&filename=index |url-status=live }}</ref> However, coins denominated in the old units were issued until 1910, and the amount of [[Twenty-five-satang coin|25 satang]] is still commonly referred to as a {{lang|th-Latn|salueng}}, as is the [[Twenty-five-satang coin|25-satang coin]].

Until 27 November 1902, the baht was fixed on a purely silver basis, with 15&nbsp;grams of silver to the baht. This caused the value of the currency to vary relative to currencies on a [[gold standard]]. From 1856 to 1864, the values of certain foreign silver coins were fixed by law, with 5 [[One-baht coin|baht]] = 3 [[Spanish dollar]] = 7 [[Indian rupee]]s.<ref name=":9">{{cite web |script-title=th:รัชกาลที่ 4 รับสั่งทำ "เหรียญกระษาปณ์" รับมือการค้ากับต่างชาติ |trans-title=King Mongkut ordered the production of western style coins as the response to the rising trades with foreigners|url=https://www.silpa-mag.com/history/article_29937|website=Silpa Watthanatham Magazine|date=27 March 2019|access-date=22 November 2020|language=th|archive-date=21 November 2020|archive-url=https://web.archive.org/web/20201121204620/https://www.silpa-mag.com/history/article_29937|url-status=live}}</ref> Before 1880 the exchange rate was fixed at 8 baht per [[pound sterling]], falling to 10 to the pound during the 1880s.

In 1902, the government began to increase the value of the baht by following all increases in the value of silver against gold but not reducing it when the silver price fell. Beginning at 21.75 baht per [[pound sterling]], the currency rose in value until, in 1908, a fixed peg to the British pound sterling was established of 13 baht per pound.

== Currency symbol ==
The [[currency symbol]] for the baht is <big>{{char|฿}}</big> (a Latin letter B with a vertical stroke). In 1986, this symbol was given a [[codepoint]] for computer use in the [[Thai Industrial Standard 620-2533]] (Thailand's [[extended ASCII|extension of ASCII]]), at position 0xDF. This national standard was subsequently subsumed into international standards as [[ISO/IEC 8859-11]] ("ISO Latin-Thai"). In turn, the ISO 8859 series were transposed into the [[Unicode]] standard,<ref>{{cite report |url=https://unicode.org/Public/MAPPINGS/ISO8859/8859-11.TXT |title=ISO/IEC 8859-11:2001 to Unicode |publisher=[[Unicode Consortium]] |date=2015-12-02}}</ref> where the symbol was allocated the codepoint {{unichar|0E3F}}.<ref>{{cite book |title=The Unicode Standard, version 1.0 |chapter=Chapter 3/2 |chapter-url=https://www.unicode.org/versions/Unicode1.0.0/ch03_2.pdf |page=80 |date=October 1991}}</ref>
The symbol is also used for the [[Panamanian balboa]].<ref name="DPD">{{cite book |title=Diccionario panhispánico de dudas |publisher=Real Academia Española y Asociación de Academias de la Lengua Española |edition=2.ª (versión provisional) |url=https://www.rae.es/dpd/ayuda/simbolos-o-signos-no-alfabetizables |access-date=16 July 2024 |language=es |chapter=Símbolos o signos no alfabetizables}}</ref>

=== Abbreviation ===
In Thai usage, the baht ({{lang|th|บาท}}) is legally abbreviated as {{lang|th|บ.}} according to Section 7 of the Currency Act, [[Buddhist Era|B.E.]] 2501.<ref>{{cite web |title=พระราชบัญญัติเงินตรา พ.ศ. 2501 (ฉบับประมวล) |url=https://www.bot.or.th/content/dam/bot/documents/th/laws-and-rules/laws-and-regulations/legal-department/2-currency-act/2-1-currency-act/2-1-1-Law-TH-CurrencyUpdated-2545.pdf |website=Bank of Thailand |access-date=6 June 2024 |language=th |date=2002}}</ref>

=== Bitcoin ===
For a time, the baht symbol was appropriated by some as a symbol for [[Bitcoin]], a cryptocurrency. Following representations,<ref>{{cite web |title=Proposal for addition of bitcoin sign |first=Ken |last=Shirriff |date=October 2, 2015 |publisher=Unicode Consortium |url=https://www.unicode.org/L2/L2015/15229-bitcoin-sign.pdf}}</ref> a separate code point ({{unichar|20BF}}, a Latin letter B with two vertical strokes) was allocated in Unicode version 10.0.<ref name="unicode-10">{{cite web |date=20 June 2017 |title=Unicode 10.0.0 |url=https://www.unicode.org/versions/Unicode10.0.0/  |access-date=20 June 2017 |publisher=Unicode Consortium}}</ref>

=== Square katakana ===
{{contains special characters|section}}
In Unicode 1.0, two codepoints were allocated to the baht, one as the currency symbol in [[Thai (Unicode block)|the Thai range]]  and one in the [[CJK Compatibility]] block as a square version of the Japanese word for "baht", written in [[katakana]] script.<ref name="Lunde" /> The CJK codepoint, {{unichar|332C}}, is documented in subsequent versions of the standard as "a mistaken, unused representation" and users are directed to {{unichar|0E3F}} instead.<ref>{{cite book |title=The Unicode Standard, Version 15.1 |chapter=CJK compatibility 3300{{ndash}}33FF |chapter-url=https://unicode.org/charts/PDF/U3300.pdf |page=3327{{ndash}}334C}}</ref> Consequently, only a few [[computer fonts]] have any content for this codepoint and its use is deprecated.<ref name="Lunde">{{cite web |title=CJK Type {{!}} CJK Fonts, Character Sets & Encodings. All CJK. All of the time. |first=Ken |last=Lunde |date= March 26, 2016 |archive-url=https://web.archive.org/web/20160629215711/http://blogs.adobe.com/CCJKType/2016/03/bahts-is-parts.html |archive-date=29 June 2016 |url=https://blogs.adobe.com/CCJKType/2016/03/bahts-is-parts.html |url-status=dead |publisher=Adobe Inc.}}</ref>

(The Japanese for "baht" is {{lang|ja|{{big|'''バ'''}}ーツ}} ({{Transliteration|ja|'''bā'''tsu}}). However, the reference glyph {{angbr|㌬}} and the character name correspond to {{lang|ja|{{big|'''パ'''}}ーツ}} ({{Transliteration|ja|'''pā'''tsu}}, from English "parts").<ref name="Lunde" />)

=== Historical symbols used before decimalization ===
Before decimalization, the Siamese government employed [[Chinese characters|Chinese]], [[Latin script|Latin]], [[Jawi script|Jawi]] ([[Malay language|Malay]]), [[Devanagari]], [[Khmer script|Khmer]] and [[Khom Thai script|Khom]], [[Tai Tham script|Lanna]], and [[Burmese script|Burmese]] scripts  in banknotes and coins, as seen. The reason is not clear, though it is a common understanding that it is to ease the facilicitation of trade within Siam. It could also be the case that at the time, the capital, Bangkok (Phra Nakhon) was still a multi-cultural city, so as to be more inclusive, the government added various other language onto the currency – though by the second series after the decimalization in the 1900s, the currency was all but monolingual.

{{lang-zh|c=圓|p=yuán|labels=no}} ({{lang|th|บาท}}): This character was use during the times of [[Mongkut|Rama IV]] to represent baht, though this was phased out by another character which is in partially and informally used today. The only occurrence of this character was in Rama IV's banknote series.

{{lang-zh|t=銖|s=铢|p=zhū|labels=no|first=t}} ({{lang|th|บาท}}): This character was in use from 1868–1925 officially on banknotes to represent baht. It is still in use today unofficially to refer to the Thai baht in general, as in {{lang|zh|泰銖}} or {{lang|zh|泰铢}}.

{{lang-zh|t=錢|s=銭|p=qián|labels=no|first=t}} ({{lang|th|สลึง}}): This character was in use from 1851–1908 officially on banknotes and coins to represent salueng.

{{lang-zh|c=方|p=fāng|labels=no}} ({{lang|th|เฟื้อง}}): This character was in use from 1851–1908 officially on banknotes and coins to represent fueang.

The notation for these Chinese character are written like they are in Thai, though there is a caveat: it is written right to left, as was the convention back then, so one baht is written {{lang|zh|圓壹}} or {{lang|zh|銖壹}}, if there are smaller units involved the notation can write like such: {{lang|zh|方銭參圓壹}} for one baht, three salueng, and one fueang.

=== ''Photduang'' coinage ===
[[File:Tailandia.jpg|thumb|Example of the Spanish dollar which was marked with the Siamese government's emblem – marking that it is legal tender]]
[[Cowrie]] shells from the [[Mekong]] River had been used as currency for small amounts since the Sukhothai period. Before 1860, Thailand did not produce coins using modern methods. Instead, a so-called "bullet" coinage was used, consisting of bars of metal, thicker in the middle, bent round to form a complete circle on which identifying marks were stamped.<ref>{{cite web |url=http://www.matichon.co.th/mtc-flv-window.php?newsid=1323259839 |script-title=th:อันซีน "พิพิธภัณฑ์มีชีวิต ธนบัตรมีเรื่องราว" แห่งเดียวในประเทศไทย [Unseen living museum - Banknotes have stories from the unique museum in Thailand]|language=th |work=Matichon |access-date=8 December 2011 |archive-url=https://web.archive.org/web/20151222112321/http://www.matichon.co.th/mtc-flv-window.php?newsid=1323259839 |archive-date=2015-12-22 |url-status=dead }}</ref><ref>{{cite book|title=เบี้ย บาท กษาปณ์แบงค์ [Cowrie, Baht, Coins, and Bank] โดย นวรัตน์ เลขะกุล|first=Nawarat |last=Lekhakum|publisher= สำนักพิมพ์สารคดี [Sarakhadee Press]|language=th |date=2009}}</ref> Denominations issued included {{frac|128}}, {{frac|64}}, {{frac|32}}, {{frac|16}}, {{frac|8}}, {{frac|2}}, 1, {{frac|1|1|2}}, 2, {{frac|2|1|2}}, 4, {{frac|4|1|2}}, 8, 10, 20, 40 and 80 baht in silver and {{frac|32}}, {{frac|16}}, {{frac|8}}, {{frac|2}}, 1, {{frac|1|1|2}}, 2 and 4 baht in gold. One gold baht was generally worth 16 silver baht. Between 1858 and 1860, foreign trade coins were also stamped by the government for use in Thailand.

==== Sukhothai and Ayutthaya ''photduang'' ====
''Photduang'', a form of currency used during the Sukhothai period, was characterized by its longer legs, which created a larger and wider hole in the middle. These coins were primarily made of silver and featured a cut across the front of each leg. This cut served a dual purpose: it authenticated the money and allowed for the quality of the silver to be tested. Over time, as the Sukhothai Kingdom declined and became a vassal state of Ayutthaya—which was established as the capital in 1350—the design of ''photduang'' evolved. The coins became rounder with shorter legs, and the central hole, while still present, grew smaller. By the end of this era, the hole disappeared completely. The cuts on the legs also reduced in size and were eventually replaced by a small elliptical nick, known as "Met Kao San," on one side of the coin.<ref name=":02">{{Cite web |last=Watanalumleard |first=S. |title=The Story of Photduang |url=http://coinmuseum.treasury.go.th/en/news_view.php?nid=118 |access-date=August 7, 2024 |website=coinmuseum}}</ref>

==== Thonburi and Rattanakosin ''photduang'' ====
The Thonburi period (1767–1782) and the Rattanakosin period, beginning in 1782, adopted the ''photduang'' design from the late Ayutthaya period. The coins from these periods had no central hole, and the legs were even shorter. A key difference was that 
[[File:Administrative Division of Rattanakosin Kingdom in 1805.jpg|thumb|453x453px|Siam at the time of podduang issue 4 (1805)]]
Thonburi ''photduang'' lacked the elliptical nick, whereas the Rattanakosin coins reintroduced this feature, similar to the Ayutthaya coins. ''Photduang'' from these later periods typically featured two stamped marks: the dynasty mark on top and the king's personal mark on the front part. The dynasty mark often symbolized the kingdom's ruling dynasty, while the king's personal mark represented the reigning monarch.<ref name=":02" />

==== Markings on the ''photduang'' ====
The markings on ''photduang'' coins varied across different periods. During the Sukhothai era, some coins bore no marks, while others had up to 11. This variation was because, at that time, individuals and merchants could produce their own money. However, from the Ayutthaya period onward, the production of ''photduang'' was monopolized by the government, making it easier to identify coins from each era. Ayutthaya ''photduang'' typically bore two marks: the dynasty mark, which could be a spoked wheel symbolizing the "Wheel of Law" from Buddhist teachings or the Chakra (Vishnu's weapon), represented by a pattern of 8 dots surrounding a central dot. The king's personal mark varied with each ruler and included symbols such as a conch shell, a Garuda bird (''khrut''), an elephant, and an anchor, each symbolizing different aspects of the king's reign or divine associations.<ref name=":02" />

=== Predecimal coinage ===
[[Rama III]] (1824–1851) was the first king to consider the use of a flat coin. He did so not for the convenience of traders, but because he was disturbed that the creatures living in the cowrie shells were killed. When he learned of the use of flat copper coins in Singapore in 1835, he contacted a Scottish trader, who had two types of experimental coins struck in England. The king rejected both designs. The name of the country put on these first coins was ''Muang Thai'', not ''Siam''.<ref>{{cite web|url=http://phila09-04.eurseree.com/cgi-bin/info/agora.cgi?cart_id=5286534.107769*KJ66o8&p_id=1196&xm=on&ppinc=search2|title=1835 Rama III unadopted design copper coin "Lotus - MuangThai"|access-date=2015-10-20|archive-date=2015-12-22|archive-url=https://web.archive.org/web/20151222110629/http://phila09-04.eurseree.com/cgi-bin/info/agora.cgi?cart_id=5286534.107769*KJ66o8&p_id=1196&xm=on&ppinc=search2|url-status=live}}</ref><ref>{{cite web|url=http://www.royalthaimint.net/ewtadmin/ewt/mint_web/ewt_news.php?nid=46&filename=index|script-title=th:เงินตรา|website=Royal Thai Mint|language=th|access-date=20 October 2015|archive-url=https://web.archive.org/web/20160304103729/http://www.royalthaimint.net/ewtadmin/ewt/mint_web/ewt_news.php?nid=46&filename=index|archive-date=4 March 2016|url-status=dead}}</ref>

In 1860, modern-style coins were introduced. These were silver [[One-sik coin|1 ''sik'']]; [[One-fuang coin|1 ''fueang'']]; 1 and 2 ''salueng''; 1, 2, and 4 baht; with the baht weighing 15.244&nbsp;grams and the others weight-related. Tin 1 ''solot'' and 1 ''at'' followed in 1862, with gold {{frac|2|1|2}}, 4, and 8 baht introduced in 1863 and copper 2 and 4 ''at'' in 1865. Copper replaced tin in the 1 ''solot'' and 1 ''at'' in 1874, with copper 4 at introduced in 1876. The last gold coins were struck in 1895.

==== Issue 0 – 1835 (trial series) ====
During the reign of King Rama III (1824–1851), an initiative was made to introduce Thailand’s first flat coinage, intended to replace the widely used cowrie shells. To aid in this modernization of the monetary system, the king employed Robert Hunter, a Scottish merchant, to produce pattern coins.<ref>Elephant-Mueang Thai - Rama III, Thailand. Numista.com. Published 2025. Accessed May 9, 2025. <nowiki>https://en.numista.com/catalogue/pieces174244.html</nowiki></ref>

The proposed designs featured an elephant motif, which bore resemblance to the coinage of Lanka (modern-day Sri Lanka). Concerned about the symbolic inappropriateness of the elephant, which could imply foreign influence or association, King Rama III ultimately rejected all of the submitted patterns. As a result, none of the proposed coins were officially adopted or denominated.

These pattern coins, though never circulated, represent an early attempt at modernization of Siamese currency prior to the eventual adoption of machine-struck coinage in the reign of King Rama IV.

The first issue of coins were commissioned by Rama IV, though it was never brought into circulation.

==== Issue 2, 3 – 1860, 1869 ====
The first circulating issue of the Siamese coins. This marked the start of the move away from using ''photduang'' currency. Though in this era, the ''photduang'' were still legal tender. In this series, the lower denominations were made of silver, and the higher ones were made of gold. These higher denominations were given nicknames: ''pot dueng'', ''pit'', and ''tot''. ''Pot dueng'' means thirty two, as in 1/32 of a ''chang''. The other nickname was the ''chinkang'' or one Chinese ''tamlueng''.<ref>{{Cite web |title=2½ Baht |url=https://en.numista.com/catalogue/pieces24271.html |access-date=2024-03-05 |website=en.numista.com |language=en}}</ref> The pit means twenty, as in 1/20 of a chang, the other name is ekkang, or one thai tamlueng.<ref>{{Cite web |title=4 Baht |url=https://en.numista.com/catalogue/pieces135454.html |access-date=2024-03-05 |website=en.numista.com |language=en}}</ref> The ''tot'' means ten, as in 1/10 of a ''chang''. The coin was also called ''thukkang'', which means two ''tamlueng''.<ref>{{Cite web |title=8 Baht |url=https://en.numista.com/catalogue/pieces24453.html |access-date=2024-03-05 |website=en.numista.com |language=en}}</ref> In the lower denominations materials such as [[tin]], [[copper]] and [[brass]] are used, since these are quite low value.

In 1857, a series of trial coins were produced. But due to the broken and rusted die pieces along with the rusted minting press, the coins of this trial series were not to the satisfaction of Rama IV, hence testing continued. The flawed coins of this series is noted to have an inconsistent and rough "sand-like" texture. In 1857-1860 small amounts of trial circulation coins were produced to circulate within the palace walls, so that the noblemen could give feedback and test the new system.<ref name=":1" />

According to the Thai Treasury, regarding the gold coins, they were minted during a period when large amounts of gold were entering Thailand. Inspired by the widespread use of gold coins in other countries, such as the gold coins of England, King Mongkut (Rama IV) ordered the production of gold coins for domestic use. These coins, with their higher value, facilitated trade as the silver coins in circulation at the time were of lower value. They were officially issued on October 29, 1863, and were withdrawn from use in 1908.<ref>เหรียญทองคำทศ พิศ พัดดึงส์ | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-king4-gold/</nowiki>‌</ref>

This series of coins was produced using manually operated machinery that had been presented as a royal gift by Queen Victoria of England. Due to the limited production capacity of these machines, the coins could not be minted in sufficient quantities to meet the country's demand. Consequently, their use was discontinued. This coincided with the arrival of steam-powered machinery, which allowed for more efficient and larger-scale coin production.<ref>เหรียญเงินตราพระมหามงกุฏ-พระแสงจักร (บรรณาการ) | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-king4-tribute/</nowiki>‌</ref> It is worth noting that coins of the half-fuang denomination were not mentioned in official announcements.<ref>เหรียญเงินตราพระมหามงกุฎ - พระแสงจักร | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-k4-1/</nowiki>‌</ref>

In 1863, the royal treasury was reportedly overflowing with gold, with this Rama IV ordered the production of gold coin in addition to the already existing silver series. Intended for circulation, the coin was released to an unfimilar populus, this the people made this coin into jewery instead. A fully intact coin with no holes is exceedingly rare today.<ref name=":1" />

In 1866, These thin copper coins, in sik (half-fuang) and siao (quarter-fuang) denominations, were produced to replace their thicker counterparts, which were heavier and had the same value. The decision to issue lighter, thinner coins was made after an incident where King Mongkut (Rama IV) distributed the thicker coins during a charitable event, and recipients were injured with head wounds and bruises. His Majesty considered that the copper coins already bore stamped marks and inscriptions (indicating that 2 coins equaled 1 fuang and 4 coins equaled 1 fuang), making them trustworthy. Therefore, thinner and lighter coins would still serve their purpose effectively without causing harm.<ref>เหรียญทองแดงตราพระมหามงกุฎ - พระแสงจักร แบบบาง | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-k4-6/‌</nowiki></ref>

With the crowning of King Rama 5 in 1868, his majesty decided to tackle the massive counfeiting of base-metal coins in his era. His majesty decided to produce a new large solot (1/128 baht) coin so that the old smaller solot coin were rendered unusable and unprofitable to counterfeit. The large solot coins were only produced for a small period of time, but the coin fulfilled its duties and eliminated a huge portion of counterfeited productions.<ref name=":1" />

These tin coins were extensively counterfeited, and brough in from Hong Kong.<ref name=":2" />

==== Issue 4 – 1875 ====
The first series to depict king Rama V, the coins of this issue were made of copper, silver, and gold. Though gold was strangely only used for the 1 ''fueang'' denomination.<ref>{{Cite web |title=1 Fuang - Rama V, Thailand |url=https://en.numista.com/catalogue/pieces33330.html |access-date=2024-03-05 |website=en.numista.com |language=en}}</ref> The new shield emblem was introduced in this issue. This shield was separated into three section. Drawing from western influences, symbols within these sections represented territories Siam was controlling. The [[Airavata|tree-headed elephant]] represented [[Rattanakosin Kingdom (1782–1932)|Siamese territory]], the bottom-left [[White elephant (animal)|elephant]] represented [[Lan Xang]], and the [[Kris|warangka]] represented Siamese Malaya.

Due to a malfunction in the minting machinery at the government mint, which prevented the production of circulating coinage, King Chulalongkorn ordered the design of this coin series and commissioned its production by a mint in Birmingham, England. This marked the first time that coins were minted abroad for circulation in Siam.<ref>เหรียญทองแดงตรา จ.ป.ร. - ช่อชัยพฤกษ์ | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-k5-2/</nowiki>

‌</ref> The copper coins in this issue were made in the same size as the coins of the United Kingdom, with the Solot being the same size as the [[Farthing (British coin)|Farthing]], the Att being the same size as the [[Halfpenny (British pre-decimal coin)|Half-Penny]], and the Siao being the same size as the [[Penny (British pre-decimal coin)|Penny]]. The silver coins differ in size to the British counterpart due to the baht being pegged to a different unit of silver. The copper coin in this case were base metal and were not pegged to any standard metal, hence their size tend to differ more throughout history. These copper coins only represent a certain amount of silver.

These silver coins were minted when the Sathit Kuang machinery was put into use in 1889 at the Sathit Kuang Coin Mint, marking the beginning of a new coinage system. The year markings started to appear on the coins from R.S. 120 (1898) onwards.<ref>เหรียญเงิน พระบรมรูป - ตราแผ่นดิน | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024.

===== Decree of October 29th 1863: Proclaiming sizes and specification of denominations =====
{{Blockquote|text=2nd day of the waning moon of the 11th month in the year of the Pig (5th cycle), equivalent to Oct. 29th, 1863, King Mongkut announced the minting of three gold coins for general use as currency. After pointing out that all important countries issued a gold coinage, but that hitherto Siam had been without one, His Majesty stated that he had issued a Royal Command to the Mint to prepare 3 values of coins, of gold 8.5 fine ("thong kham neiá pát sétsong"), i.e., gold leaf of the Chop Ann Seng, the first equal in value to 8 Ticals silver, the second to 4 Ticals, and the third to 2½ Ticals, the last named to represent the weight of a Chinese "tael." He went on to say that the types of these coins had been borrowed from those of the English sovereign and half-sovereign; but that the latter coins were an alloy of gold and copper, containing of the latter 1 in 12 (i.e. 22 carat gold) for the purpose of hardening the coin. He was afraid, however, that the Siamese folk would askance at gold coins which were not pure.

....

On one side (the obverse) there is a picture of the Royal Crown in the centre. There are Royal Umbrellas supporting it on both sides. There are branches of trees, looking like flames, added to the background of the coin.

On the other side (the reverse) is a picture of the "Chakr". In the heart of the "Chakr" is a picture of an Elephant, symbolical of the Kingdom of Siam. On the outside of the circle round the "Chakr", in the case of the Tical value, are 8 stars, each star representing 1 Fuang; the 2 Salung piece has 4 stars, representing 4 Fuang; the Salung has two stars, and the Fuang 1 star.|author=Royal Siamese Government|title=Decree of October 29th, 1863}}
===== Decree of June 29th 1874: Proclaiming the use of temporary paper money, in order to transition into the new series of coins =====
{{Blockquote|text=The tin Atts and Solots which had been minted and put into circulation in the place of cowries in the last reign have been much counterfeited, and when the legal value of the Att was subsequently reduced to twenty cowries, a great many of these coins disappeared, while no more have been manufactured owing to the fact that copper ones could not be produced with the existing machinery. Bigger machines of greater power are being ordered, and as soon as they are installed and ready for working, the Mint will produce such copper coins as will challenge the ingenuity of counterfeiters. At present, however, the public are taxed with the token coins of the gaming house Farmers (Pee, q. v.), which are accepted only in their respective issuing districts and only during their issuers' tenure of the district monopoly. H. M. the King has now been pleased to command the printing of paper "atts", each sealed with the Royal Arms of two different sizes, and all numbered in consecutive order to differentiate them from each other. Should any note be found with the same number as another, the counterfeit note will probably be discovered after a careful examination of the seal-marks and the framework design. These paper "atts" shall be legal currency for the time being until copper coins can be issued after the installation of the new machinery. Anyone having more of them than he needs may present them for payment at the Treasury between 11 A. M. and 3 P. M., and their value will be paid him that same day. Should any of the notes presented be torn in two or more places, it will be accepted as long as the pieces can be formed into one and the same note, and no commission whatever will be charged on its payment.

By command of H. M. the King, therefore, Phya Rajbhakdi Sriratanarajsombat, Knight Grand Cross of the Order of the Crown of Siam and Knight Grand Cross of the Order of Chula Chom Klao, hereby notifies to all, high and low, that, from the first day of the waxing moon in the second eighth month of the year of the Dog, sixth of the current cycle, the Treasury will issue paper "atts" instead of tin coins till the Mint is completely furnished (when copper coins will be manufactured to replace these paper "atts"), and that these paper "atts" may be freely used by the public without fear of loss.

Proclaimed on Monday, the first day of the waning moon in the first eight month of the year of the Dog, sixth of the current cycle, Chula Era 1234, being the seventh year of the present Reign.|author=Royal Siamese Government|title=Decree of June 29th, 1874}}<ref name=":2" />

This was a minor issue (not all denominations were updated), in which the lower denominations' designs were updated to incorporate the three-parted shield into the design. This shield is a part of the [[Emblem of Thailand|national seal]] at the time. This copper coin was produced to replace previous versions and was minted in England, with additional production by the Royal Mint of Thailand.<ref>เหรียญทองแดง พระบรมรูป - ตราพระสยามเทวาธิราช | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department.

=== Decimal coinage ===
The decimalization of the Thai baht came about at the end of the 19th century. The Minister of Treasury, [[Jayanta Mongkol|Jayanta Mongkol, the Prince Mahisara Rajaharudaya]], suggested to King Rama V that decimalization would make counting easier and further modernize Siam. Initially, there would be one superunit, ''chang'', and one subunit, ''at''. with the baht being in the middle. In summary, 64 ''at'' = 1 baht = 1/80 ''chang''. In reality, this was just a simplification of the old system, which was scrapped.<ref>{{Cite web |title=2½ Satang - Rama V, Thailand |url=https://en.numista.com/catalogue/pieces27448.html |access-date=2024-03-05 |website=en.numista.com |language=en}}</ref> In which, during the period of 1902–1908, Siam went back to the old system. Though in comparison, ''at'' is used as the subunit in Laos, compared to the satang in the Thai baht. The second attempt came at the end of Rama V's reign, where it was more widely accepted and put into effective use.

In 1897, the first coins denominated in satang were introduced, [[cupronickel]] {{frac|2|1|2}}, 5, 10, and 20 satang. However, 1 ''solot'', 1, and 2 ''at'' coins were struck until 1905 and 1 ''fueang'' coins were struck until 1910. In 1908, holed 1, 5, and 10 satang coins were introduced, with the 1 satang in bronze and the 5 and 10 satang in nickel. The 1 and 2 ''salueng'' were replaced by 25 and 50 satang coins in 1915. In 1937, holed, bronze {{frac|2}} satang were issued.

In 1941, a series of silver coins was introduced in denominations of 5, 10, and 20 satang, due to a shortage of nickel caused by [[World War II]]. The next year, tin coins were introduced for 1, 5, and 10 satang, followed by 20 satang in 1945 and 25 and 50 satang in 1946. In 1950, [[aluminium bronze]] 5, 10, 25, and 50 satang were introduced whilst, in 1957, bronze 5 and 10 satang were issued, along with 1-baht coins struck in an unusual alloy of copper, nickel, silver and zinc. Several Thai coins were issued for many years without changing the date. These include the tin 1942 1 satang and the 1950 5 and 10 satang, struck until 1973, the tin 1946 25 satang struck until 1964, the tin 50 satang struck until 1957, and the aluminium bronze 1957 5, 10, 25, and 50 satang struck until the 1970s. Cupronickel 1-baht coins were introduced in 1962 and struck without date change until 1982.

In 1972, cupronickel 5-baht coins were introduced, switching to cupronickel-clad copper in 1977. Between 1986 and 1988, a new coinage was introduced, consisting of aluminium 1, 5 and 10 satang, aluminium bronze 25 and 50 satang, cupronickel 1 baht, cupronickel-clad copper 5 baht and bimetallic 10 baht. Cupronickel-clad steel 2 baht were introduced in 2005.

==== Issue 6 – 1897 (transitional) ====
The old monetary system of Siam was based on a binary system that proved challenging for accounting purposes. This system initially consisted of three main units of currency: '''Chang''', '''Baht''', and '''Att'''. Under this system, there were 64 Att to 1 Baht and 80 
[[File:Administrative Division of Siamese Kingdom in 1900.jpg|thumb|Siam at the time of coin issue 6 (1897)]]
Baht to 1 Chang. Despite its widespread use, the system’s complexity made it difficult to manage and calculate. Recognizing the inefficiencies, the Minister of Treasury proposed to King Rama V that Siam’s currency system should be decimalized. The proposal aimed to modernize the monetary system and align it with the decimal systems increasingly adopted by other countries at the time. King Rama V approved the transition to a decimal-based currency, which simplified accounting processes. The transition to a decimal currency system faced numerous challenges even before the new coins were issued. Notably, the word "Anachak" (อาณาจักร) was initially misspelled as "อานาจักร," causing controversy. King Rama V intervened, insisting that the most accurate phrasing should be "Siam Ratcha-Anachak" (สยามราชอาณาจักร; Kingdom of Siam). Despite the initial enthusiasm for the decimal system, the new coins struggled to gain popularity among the public. Many people were unfamiliar with the decimal system and preferred the traditional currency. Consequently, the new coins quickly faded from circulation, forcing the government to continue producing coins under the old system.

The production of coins from the old system persisted until '''RS 127 / BE 2451 / AD 1907'''. Ultimately, both pre-decimal coins and the early decimal coins were demonetized on '''May 17, RS 128 / BE 2452 / AD 1909'''. Citizens were given a grace period to exchange the demonetized coins for the new decimal currency, with the deadline set for '''May 16, RS 128 / BE 2452 / AD 1910'''. This gradual shift is shown in the fact that coins after the transition often switched between three calendar systems, the CS (Chulasakarat) system, the RS (Rattanakosin Sok) system, the BE (Buddhist Era / Phutthasakarat) system.<ref>2½ Satang - Rama V, Thailand.

During the year 1897, it is persumed that Rama V had arranged this series to be made during his tour in europe.<ref name=":2" /> This series was denonetized in 1908.<ref name=":2" />

===== Royal Proclamation of 21st. August R. S. 117 (1898) : The proclaimation of issuance of decimal currency =====
{{Blockquote|text=Formerly the subsidiary currency had the following values: 800 cowries equal one Fuang, 2 Fuang equal one Salung, 4 Salung equal one Tical. At present we are using the following copper coins as fractions of the Fuang: 4 Atts (Songpai), 2 Atts (pai), 1 Att, and ½ Att (Solot). These were struck on the obverse with the Royal Monogram ร.ป.ร. and the Little Crown above the letter ค, and also with the inscriptions Kingdom of Siam and Fifth Reign; on the reverse with a wreath of laurel leaves, in the middle of which appears the denomination of the particular coin and the date. Their issue was notified in the year of the Pig, Chula Era 1237, and the year of the Rat, Chula Era 1238.

There are also copper coins of another design for the 2 Atts (Pai), the Att, and the ½ Att (Solot) only. These have on the obverse His Majesty's effigy with the following inscription round the border: Chulalongkorn P. R. Phra Chula Chom Klao Chao Krung Siam, and on the reverse the figure representing ‘Siam’ holding a staff and seated on a shield. Their issue was notified in the year of the Pig, Chula Era 1249.

All these coins are valued in accordance with the original notation. In the accounts the figures of a sum are accordingly entered in three columns: Catties, Bahts, and Atts — 64 Atts, or 6,400 cowries, equalling one Tical and 80 Ticals one Catty, which is the unit. Now the system of keeping accounts is to be changed to a decimal one, reducing the number of columns to two only: Ticals and Satang. The value of a Satang is to be a hundredth part of a Tical, so that the summing up of a number of figures will be a much simpler task.

H. M. the King has therefore been pleased to command the mintage of subsidiary nickel coins of 4 denominations, all having on the obverse the image of the three-headed Elephant and the inscriptions Kingdom of Siam and Year 116, but on the reverse each denomination shall show its respective nominal value in letters and large numerals in the centre, thus twenty Satang, 20; ten Satang, 10; five Satang, 5; and two and a half Satang, 2½.

Being free from oxidizability and very portable, these nickel coins will form a more suitable currency than the copper ones. Both kinds of the latter will, however, still be legal token coins for their original nominal value, side by side with those of the Satang denominations, and the one may be freely demanded from the Treasury in exchange for the other at its full proportionate nominal value.

On and from the 21st. September R. S. 117 (1898), the nickel coins shall be current at their respective values mentioned above.

Proclaimed on 21st. August R. S. 117 (1898), being the 10,874th. day of the present Reign.|author=Royal Siamese Government|title=Royal Proclamation of 21st. August R. S. 117 (1898)}}<ref name=":2" />

==== Issue 7, 8, 9 – 1908, 1913, 1929, 1939 ====
[[File:Administrative Division of Siamese Kingdom in 1900.jpg|thumb|297x297px|Siam at the time of coin issue 7 (1900)]]
In 1908, the Siamese government commissioned the Monnaie de Paris mint to produce a new series of coins for Rama V. These coins were engraved by A. Patey and became the most popular coins to collect amongst the collector today, though with massive conterfeit problems. The coins' shipment were delayed and were shipped to Siam around the time of the passing of Rama V, and so the coins were never put in to circulation. With this, the mint saw fit that the designs were to be adapted to depict Rama VI.<ref name=":1" />

These coins were all produced abroad, and they feature changes in year formatting and design differences over time. The coins were initially produced with the R.S. year system but transitioned to using the B.E. system from 1913 onwards.<ref>เหรียญนิกเกิล ทองแดง ตราอุณาโลม - พระแสงจักร | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-k6-1/</nowiki>

‌</ref> The 1 Baht coins were replaced with banknotes starting in 1918 due to the high cost of silver. The 2 Salung and 1 Salung coins experienced changes in metal composition due to fluctuating silver prices during World War I, and these coins have slight design variations based on these changes.

During issue, there were also various debasements of the silver content of these coins. Initially, the composition was 80% silver and 20% copper. In 1918, during World War I, silver prices surged, leading to a change in the composition to 65% silver and 35% copper. In 1919, the silver percentage dropped further to 50% silver and 50% copper. After the war, in 1919, the composition returned to 65% silver and 35% copper.<ref>เหรียญเงิน พระบรมรูป - ตราไอราพต | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-k6-2/</nowiki>

‌</ref> In 1917, the price of silver rose and exceeded the face value of silver coins. The coins were then melted down and sold. The government solved this by changing the pure silver coin to alloy. Vajiravudh eventually forbade exports of Siamese coins. In 1918, the usage of 1-baht coins was nullified and 1-baht banknotes were introduced. Coins were recalled and kept as a national reserve.

Near the end of this issue of coins, the transition into decimal currency was completed. The Rama VII coin was produced in two denominations, 50 Satang and 25 Satang, and marked the transition from the old currency system of "สองสลึง" (two salung) and "หนึ่งสลึง" (one salung) to the new system using Satang as a unit of currency.<ref>เหรียญเงิน พระบรมรูป - ตราช้างทรงเครื่อง | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-k7-1/</nowiki>

‌</ref> Though, people today still refer to these denomination using the old terminology.

This series of coins is distinctive as it lacks the royal insignia and the state seal, which were commonly featured in earlier designs. This series also includes a 20 satang denomination; thus at one point the 25-satang and the 20-satang circulated at the same time.<ref>เหรียญเงิน ทองแดง ตราลายกระหนก | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024. Accessed December 20, 2024. <nowiki>https://www.treasury.go.th/th/coin-k8-3/</nowiki>‌</ref> The half-satang was introduced in 1937 to address the issue of low-value currency units in Thailand. The value of 1 Satang was considered too high for certain low-priced items, causing economic hardship for the poor. Previously, 1 Baht could be exchanged for 128 Solot, but after the switch to Satang, 1 Baht was only equivalent to 100 Satang. The introduction of this coin aimed to make it easier for ordinary people to purchase items without the burden of inflated prices. The coin was produced only once and was discontinued soon afterwards. It was minted in Japan and first issued on July 12, 1937.<ref>เหรียญทองแดง ครึ่งสตางค์ ตราอุณาโลม - พระแสงจักร | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department. Published 2024.

In 1942, a group of denominations switched material due to the costs of [[World War II]]: the 1-satang coin lost its hole in the middle and was made smaller.<ref>เหรียญดีบุก ตราลายกระหนก พ.ศ. 2485 | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department.

==== Issue 11 – 1946 ====
This was the first series minted in the reign of [[Ananda Mahidol|King Ananda Mahidol (Rama VIII)]], and it marked the return of [[Emblem of Thailand|national symbols]], such as the [[Garuda]] emblem, which had been used as the [[Seal (emblem)|national seal]] since the [[Ayutthaya Kingdom|Ayutthaya period]]. This emblem, created during

the reign of [[Chulalongkorn|King Chulalongkorn (Rama V)]], became the national seal to be used permanently, avoiding the need for a new one with each reign. There are two versions of this series minted in the same year, the young portrait and the teen portrait.<ref>เหรียญดีบุก พระบรมรูป - ตราพระครุฑพ่าห์ (ทรงเจริญพระชนมพรรษา) | กรมธนารักษ์. กรมธนารักษ์ : The Treasury Department.

After [[World War II|World War 2]], the government instructed the mint to start the production of coins depicting [[Ananda Mahidol|Rama VIII]], since prior to this coins with no royal portrait were minted. These coins were made with pure [[tin]]. These coins were made with particularly low quality [[tin]]. During circulation, a lot of the coins from this series were damaged, lost, or rendered unusable. Even so, after the death of [[Ananda Mahidol|Rama VIII]], the mint continue to produce this series of coins until the burial of Rama VIII, a tradition seen in the latest series of coins where new series were not introduced until after the coronation. Thus, this series of coins were used for 4 years after the passing of [[Ananda Mahidol|King Ananda Mahidol (Rama VIII)]].<ref name=":1" />

While this series lacks a circulating [[One-baht coin|1 baht coin]], a trial piece were produced but never released into circulation.,<ref name=":1" /> the coin was 30.5&nbsp;mm in diameter and made with tin. As a reference, this is the size of 5 baht coin up until issue 16 coins, or the last Rama 9 series of coins.

=== Current coinage ===
The current coin series is the 17th issue.

In 2008, in the 16th issue, the [[Ministry of Finance (Thailand)|Ministry of Finance]] and the Royal Thai Mint announced the 2009 coin series, which included changes in materials to reduce production costs as well as an update of the image on the obverse to a more recent portrait of the king. The two-baht coin, confusingly similar in color and size to the one-baht coin, was changed from nickel-clad low-carbon steel to aluminium bronze. New two-baht coin was the first of the new series released on 3 February 2009, followed by the satang coins in April, a five-baht coin in May, a ten-baht coin in June, and a one-baht coin in July 2009.

In 2018, the Royal Thai Mint and the Ministry of Finance issued a new series of general circulation coins, featuring the same standard specifications, but feature a portrait of its current king, [[Vajiralongkorn]].

=== Names used on coins ===
Thai kings traditionally had 2 names: regnal, and personal. In everyday life, personal name are used more often than regnal names. A good example of this is [[Narai|King Narai]], whose regnal name is [[Narai|King Ramathobodi III]]. The personal names of king also have variations in itself. An example is [[Vajiralongkorn|Rama X]]'s personal name: ''Vajiralongkorn'', in which the variation one might see is ''Vajiraklao''. So when the new coinage was being carried out, the question of "what name should the mint depict?" pops up. Initially it's a mix of the variations of the personal names, later after King [[Ananda Mahidol|Rama VIII]], and the switch to constitutional monarchy along with the changing of the country name to Thailand, the coin now use both regnal (alternative name) and personal names.

=== Calendar systems of Thai coinage ===
Over the course of Siamese coinage history, various calendar systems were used. The first one to be applied onto the coins was the [[Chula Sakarat|burmese calendar system or Chula Sakarat (C.S.)]], which was subsequently supplanted by the [[Thai calendar|Rattanakosin Sok]] system (R.S.) which started at the founding of the [[Rattanakosin Kingdom (1782–1932)|Rattanakosin Kingdom]]. The system in use right now is the Phuttha Sakarat system or the Buddhist calendar (B.E.)

{{main|Banknotes of the Thai baht}}

In 1851, the government issued notes for {{frac|8}}, {{frac|4}}, {{frac|3|8}}, {{frac|2}} and 1 tical, followed by 3, 4, 6 and 10 tamlueng in 1853. After 1857, notes for 20 and 40 ticals were issued, also bearing their values in [[Straits dollar]]s and [[Indian rupee]]s. Undated notes were also issued before 1868 for 5, 7, 8, 12 and 15 tamlueng, and 1 chang. One at notes were issued in 1874.

In 1892, the treasury issued notes for 1, 5, 10, 40, 80, 100, 400 and 800 ticals, called "baht" in the Thai text.

On 10 September 1902, the government introduced notes which were printed by [[De La Rue|Thomas De La Rue & Company Limited, England]], during the reigns of Kings [[Chulalongkorn|Rama V]] and [[Vajiravudh|Rama VI]], denominated 5, 10, 20, 100 and 1000 ticals, still called baht in the Thai text — each denomination having many types,<ref>{{cite web

===== Series 1 =====
Series 1 was chosen due to the series which precedes this were non-decimal. Series 1 banknotes was the first series to be produced by Thomas De La Rue & Company Limited. In 1900, Charles James Rivett Carnac, a Royal Treasury Ministry advisor proposed that the Siamese baht followed the issuances of banknotes followed the British standard. The banknote department was established quickly thereafter. The main characteristic of this series was that the notes were one-sided and multilingual, containing [[Chinese character|Chinese]], [[Malay language|Malay]] (in [[Jawi script]]), and [[Latin script|Latin]] scripts.<ref>{{Cite web |title=1st Series Thai Banknotes |url=http://www.siambanknote.com/banknote-appraisal/1st-series-thaibanknote-price.htm |access-date=2023-09-11 |website=www.siambanknote.com}}</ref> It was also the last series to use the term "tical" to refer to the Thai baht and the largest in term of size of the circulated notes.

===== Series 17 =====
On the occasion of there being now 10 kings within the [[List of Thai monarchs|current dynasty]]. The central bank of Thailand decided that this series would commemorate all the kings of the Chakri dynasty. The front depicting the [[Vajiralongkorn|King Rama X]], while the back depict 2 kings. While initially, the series was printed on cotton-paper, on March 24, 2022, the central bank decided to upgrade the material to polymer. This would set a trend where more denominations is to be converted into polymer. This is seen when on the November 21, 2025, the 50-baht and 100-baht note was converted into polymer.

==Money and unit of mass==
''Ngoen'' ([[wikt:เงิน|เงิน]]) is Thai for "[[silver]]" as well as the general term for [[money]], reflecting the fact that the baht (or tical) is foremost a unit of [[mass|weight]] for [[precious metal]]s and [[gemstone]]s. One baht = 15.244 [[gram]]s.<ref>[http://www.bangkokpost.com/news/local/30756/a-sure-bet-or-fool-gold "A sure bet or fool's gold?"], ''Bangkok Post'' 2010-01-10{{Dead link|date=October 2018}}</ref> Since the standard purity of Thai [[gold]] is 96.5 percent, the actual gold content of one baht by weight is 15.244 × 0.965 = 14.71046&nbsp;grams; equivalent to about 0.473 [[troy ounce]]s. 15.244&nbsp;grams is used for [[Bullion#Bullion|bullion]]; in the case of [[jewellery]], one baht should be more than 15.16&nbsp;grams.

The Bank of Thailand adopted a series of exchange controls on 19 December 2006, which resulted in a significant divergence between offshore and onshore exchange rates, with spreads of up to 10 percent between the two markets. Controls were broadly lifted on 3 March 2008 and there is now no significant difference between offshore and onshore exchange rates.<ref>{{cite news | url=http://in.reuters.com/article/idINSP20869920080303 | work=Reuters | title=UPDATE 1-Onshore and offshore Thai baht converge, c.bank seen | date=3 March 2008 | access-date=12 September 2010 | archive-date=22 November 2020 | archive-url=https://web.archive.org/web/20201122120207/https://in.reuters.com/article/idINSP20869920080303 | url-status=dead }}</ref>
