The bi-metallic Thailand ten-baht coin is a denomination coin of the Thai Baht, the currency unit of Thailand.

Like every standard-issue coin in Thailand, its obverse features the King of Thailand, Vajiralongkorn Bodindradebayavarangkun and previously Bhumibol Adulyadej. The newest coin features King Vajiralongkorn's royal monogram on its reverse side while the previous set featured Wat Arun Ratchawararam Ratchawora Mahavihara seen from the Chao Phraya River.

Ten-baht coin has been used as a commemorative coin for many occasions since 1971. As of March 2012, there are one silver, twenty-three nickel, twenty-three cupronickel and fifty-eight bi-metallic face-valued ten-baht commemorative coin series.


Raised dots corresponding to Braille cell dot 1 and dots 2-4-5, which correspond to the number 10, are at the 12 o'clock position on the reverse of the standard-issue 10-baht coin. Braille enumeration does not appear on coins of other denominations, nor on ten-baht coins frequently issued as commemorative coins (for example, the 50th and 60th Anniversary of Accession to the Throne of King Bhumibol Adulyadej.)

The bi-metallic ten-baht coin is very similar to the two–euro coin, which first minted in 2002, in size, shape and weight and likewise consists of two different alloys. Vending machines that are not equipped with an up-to-date coin-checking system might therefore accept them as €2 coins. This similarity is because both coins are minted on the model of the defunct Italian 500 lire coin, the world's first modern bi-metallic coin. To mint its 10 baht coin in 1988, the Thai government had to be allowed by the Italian mint, which had an international copyright over bi-metallic minting. The 10 baht is a perfect copy of the 500 lire coin even in its alloy, being made of acmonital for the outer ring and bronzital for the centre plug, but slightly larger (26 mm to 25.80 mm) and heavier (8.5 g to 6.8 g).


2009 changes[]

In 2009, a new series of Thai baht coins were released in circulation. The Ten-baht coin was issued for this series, the difference is the redesign of the portrait of King Bhumibol Adulyadej on the obverse, to reflect his current age. The reverse side remained the same from previous issues.

2018 series[]

The Ministry of Finance announced on March 28, 2018 that the first coins featuring the portrait of His Majesty King Maha Vajiralongkorn Bodindradebayavarangkun will be put in circulation on April 6.
