1 Baht Coin

Thailand · This specific coin is likely from around 2008 (BE 2551) or later, featuring the current King Maha Vajiralongkorn portrait, but the obverse image provided doesn't show the King's portrait. The depicted temple is Wat Arun (Temple of Dawn), which was featured on the reverse of 1 Baht coins from 1986 (BE 2529) to 2017 (BE 2560) during King Bhumibol Adulyadej's reign, and continues to be on the reverse of the coins with King Maha Vajiralongkorn's portrait. Without seeing the obverse with the monarch's portrait, an exact year is difficult to pinpoint from this image alone.
