1 Satang - Rama X 1st portrait

The tiny aluminium satang denominations were retained in Thai coinage largely as accounting units rather than practical currency — prices rounded away from them decades ago. This issue marks the transition to Rama X, Vajiralongkorn, who ascended following the death of his father Bhumibol Adulyadej in October 2016 after a 70-year reign, the longest of any monarch in Thai history. The mint required nearly two years before circulating coins bearing the new king's portrait entered production.
