Understanding Thailand’s Coin System
Thailand uses the Thai Baht (THB) as its currency, with coins playing a crucial role in daily transactions. The coin system consists of six denominations: 25 satang, 50 satang, 1 baht, 2 baht, 5 baht, and 10 baht. Here’s the key: 100 satang equals 1 baht, making satang coins the “cents” of Thai currency.
According to Thai law, there’s a limit to how many coins you can use at once, for example, you can only use satang coins up to a maximum value of 10 baht per transaction. This explains why many vendors prefer to round prices to the nearest baht.
The Big Coins: Easy Identification for Beginners
10 Baht Coin: The Distinctive Two-Tone Giant
The 10 baht coin is impossible to miss, it’s the largest coin in circulation at 26mm diameter. This distinctive coin features a silver-color ring with a brass-color center, making it bimetallic and easily recognizable. The reverse side showcases Wat Arun (Temple of Dawn) in Bangkok, one of Thailand’s most iconic landmarks. Many Europeans have noted that the 10-baht coin is “close in size and style to a $2 Euro,” which can be a helpful reference point.
Tourist Tip: This coin replaced the 10 baht banknote in the early 1990s, so you won’t see any 10 baht bills in circulation.
5 Baht Coin: The Silver Standout
The 5 baht coin measures 24mm, making it slightly smaller than the 10 baht coin. It has a fully silver-colored finish. The reverse features Wat Benjamabophit, also known as the Marble Temple. Many American tourists have noted that the 5 baht coin is “close in size to a US quarter,” which can be a helpful reference point.
The Tricky Middle: Coins That Confuse Tourists
2 Baht Coin: The Shape-Shifter
Here’s where things get interesting, and confusing. The 2-baht coin appears in both gold and silver, depending on the year of minting.
The Mint switched to a brass-colored design after 2005, adding an image of the Golden Mountain at Wat Saket in Bangkok.
The original 2005-2007 version was silver-colored and looked remarkably similar to the 1-baht coin. This similarity was so problematic that many people use a permanent marker to write the number “2” on these coins to prevent mix-ups.
Tourist Alert: Some older ticket vending machines (BTS Skytrain, MRT Metro, Airport Rail Link) cannot accept 2 baht coins, so keep this in mind when using public transport.
1 Baht Coin: The Silver Standard
The 1 baht coin measures 20mm across, has a silver color, and shows the chedis (spires) of the Temple of the Emerald Buddha on the back. You’ll use this coin most often for small purchases and tips.
The Tiny Ones: Satang Coins Most Tourists Ignore
50 Satang: The Copper Half
The 50 satang coin is copper colored and worth half a baht (about 1.5 cents USD). At 18mm diameter, it features the chedi at Wat Prathat Doi Suthep in Chiang Mai. These coins are mostly used in supermarkets and convenience stores like 7-Eleven.
25 Satang: The Tiny Brass Coin
The smallest coin at just 16mm, the 25 satang piece is brass-colored and worth about a quarter of a cent USD. Many street vendors won’t accept these coins, so don’t be surprised if they’re refused.

Cultural Considerations: Respecting Royal Currency
Every Thai coin features the image of the King, making proper treatment essential. It’s considered offensive to carry money in your back pocket, as this means sitting on the King’s image. Additionally, never step on coins or treat them disrespectfully.
Practical Tips for Smooth Transactions
- Stock up on small coins: Public transport ticket machines primarily accept coins (10, 5, and 1 baht), so always carry these denominations.
- Satang strategy: Many vendors round prices to the nearest baht, so use your satang coins at supermarkets or 7-Eleven stores where they’re more likely to accept them.
- Temple coins: Each coin showcases a different famous Thai temple, making them educational souvenirs that tell stories of Thailand’s rich Buddhist heritage.
- Machine compatibility: Be aware that older vending machines may not accept certain coins, particularly the silver 2 baht coins from 2005-2007.
From Confusion to Confidence
Mastering Thai coins isn’t just about making transactions, it’s about showing respect for Thai culture and navigating daily life with confidence.

With this guide in hand and a little practice, you’ll quickly start handling Thai coins like a local. Everyday transactions will feel easier, and your Thai adventure will run more smoothly.

Quick FAQ about Thai Currency
The currency in Thailand is the Thai Baht, abbreviated as THB and represented by the symbol ฿. The Thai Baht is the sole legal currency used across Thailand, including Bangkok and all major tourist destinations. Whether you’re shopping at street markets, paying for hotels, or booking a private tour guide in Bangkok, everything is priced in Thai Baht. The currency has been Thailand’s official money for over a century and is one of the most stable currencies in Southeast Asia. You can exchange foreign currency at banks, licensed exchange booths, and airports throughout Bangkok and Thailand. ATMs dispensing Thai Baht are widely available in cities, tourist areas, and even smaller towns across the country.
Thai Baht denominations are divided into banknotes and coins. Thai Baht banknotes come in five denominations: 20 baht (green), 50 baht (blue), 100 baht (red), 500 baht (purple), and 1,000 baht (brown/grey). Thai Baht coin denominations in regular circulation include 1 baht, 2 baht, 5 baht, and 10 baht. There are also satang coins, though these are rarely encountered. The full Thai Baht denominations list runs from the tiny 1 satang coin up to the 1,000 baht note, giving THB a wide range of denominations for everyday transactions. Smaller denominations like 20 and 50 baht notes are the most practical for street food, tuk-tuks, and market shopping in Thailand.
Thai Baht coins currently in circulation include the 1 baht, 2 baht, 5 baht, and 10 baht coins. The 1 baht coin is small and silver-colored, the 2 baht is slightly larger with a gold tone, the 5 baht coin is silver with a copper rim, and the 10 baht coin is the largest with a distinctive two-tone silver and copper design. Satang coins technically still exist as Thai currency but are almost never seen in daily use. Thai coins are used for everything from vending machines to temple donation boxes. Each coin features an image of the Thai King on one side, making Thai Baht coins both functional currency and a reflection of Thailand’s deep respect for the monarchy.
The 1 Baht coin is a small, silver-colored coin made from nickel-plated steel. One side features a portrait of the Thai King, while the reverse displays the image of Wat Phra Kaew, the Temple of the Emerald Buddha in Bangkok. The Thailand 1 Baht coin measures about 20mm in diameter, making it one of the smaller coins in everyday circulation. It is smooth-edged and lightweight. The Thai 1 Baht coin is the most commonly used coin in Thailand, handy for small purchases, donations at temples, and coin-operated machines. Older 1 Baht coins may feature the image of the previous King, Rama IX, while newer issues feature King Rama X. Both versions remain valid currency.
Thai money is colorful and easy to distinguish between denominations. Thai Baht banknotes each have a unique color — 20 baht is green, 50 baht is blue, 100 baht is red, 500 baht is purple, and 1,000 baht is brown/grey. All Thailand money features a portrait of the Thai King on the front, with significant temples and royal landmarks on the reverse. Thai Baht bills are made from a mix of polymer and paper depending on the denomination, with the 20 baht note now using durable polymer. Thai coins range from the small silver 1 baht to the larger two-tone 10 baht. Thailand’s money is well-designed with advanced security features including holographic strips, watermarks, and color-shifting ink.
There are five Thai Baht bills currently in circulation: 20, 50, 100, 500, and 1,000 baht. The 20 baht note is the smallest denomination banknote, green in color and now printed on polymer for durability. The 50 baht bill is blue, the 100 baht note is red, the 500 baht bill is purple, and the 1,000 baht note is the largest denomination, colored brown and grey. All Thai currency notes feature King Rama X on the front. Thai Baht bills vary slightly in size, with larger denominations being physically bigger. For practical purposes, carrying plenty of 20 and 100 baht notes is recommended, as many street vendors and taxi drivers in Bangkok struggle to break 500 or 1,000 baht bills.
The 10 Baht coin is the largest and highest-value coin in regular Thai currency circulation. It features a distinctive two-tone design with a copper-colored center and a silver-colored outer ring, making it easy to identify among other Thai coins. The 10 Thai Baht coin measures approximately 26mm in diameter. One side displays a portrait of the King of Thailand, while the reverse shows Wat Arun, the iconic Temple of Dawn in Bangkok. The Thailand 10 Baht coin is commonly used for vending machines, small purchases, and local transport. Its bi-metallic design is sometimes compared to the Euro 2 coin. Visitors should note that some older 10 baht coins may look similar to certain foreign coins.
Thai currency is called the Thai Baht. The official name in the Thai language is “บาท” (Baht), and its international currency code is THB. The money in Thailand has been called the Baht since 1897, replacing the earlier name “Tical” that was used in international trade. The Baht is subdivided into 100 satang, though satang are rarely used in modern Thailand. Before the current monetary system, Thailand’s currency included bullet coins and cowrie shells. Today the Thai Baht is managed by the Bank of Thailand and is the only accepted legal tender throughout the country. When people ask what Thailand’s currency is called, the simple answer is always the Baht — one word used by locals and visitors alike.
The 2 Baht coin is a gold-toned coin slightly larger than the 1 baht, measuring about 21.75mm. It features the King’s portrait on one side and the Buddhist Sanam Luang pavilion on the reverse. The 5 Baht coin is silver-colored with a distinctive copper rim, measuring around 24mm in diameter. Its reverse displays Wat Benchamabophit, the famous Marble Temple in Bangkok. Both Thai coins are commonly used in everyday transactions across Thailand. The 50 Baht coin also exists but is a commemorative issue and rarely found in general circulation. Together with the 1 and 10 baht coins, these denominations cover most small cash transactions at markets, convenience stores, and street food stalls throughout Bangkok and Thailand.
A satang is the smallest unit of Thai currency, with 100 satang equaling one Thai Baht. Satang coins were once common in Thailand but have become nearly obsolete in daily transactions. Denominations that technically still exist include 1, 5, 10, 25, and 50 satang coins. In practice, the only satang denomination you might occasionally encounter is the 25 or 50 satang coin, usually as change at supermarkets like Tops or Big C. Thai satang coins are tiny and lightweight, often mistaken for tokens. While prices at Thai supermarkets and petrol stations may still include satang amounts, most vendors simply round to the nearest baht. Satang remain a curiosity of Thai currency rather than a practical denomination for visitors.
The currency used in Bangkok is the Thai Baht, the same currency used throughout all of Thailand. Bangkok, as Thailand’s capital and main tourist hub, has extensive currency exchange options including bank branches, licensed exchange booths in shopping malls, and airport counters. Popular exchange areas for visitors include Sukhumvit Road, Silom, and Khao San Road, where rates tend to be more competitive than at airports. ATMs accepting international cards are found on virtually every block in Bangkok. Credit cards are widely accepted at Bangkok hotels, department stores, and upscale restaurants, though cash in Thai Baht remains essential for street food, markets, tuk-tuks, and smaller shops. Always carry smaller Bangkok currency denominations for daily spending.
