12000 Baht - 60th Anniversary of Reign

Issued to mark King Bhumibol Adulyadej's 60th year on the throne in 2006 — making him the longest-reigning monarch in Thai history at that point and the longest-reigning head of state in the world at the time of his death in 2016. The 12,000 baht denomination placed this well beyond circulation, minted strictly as a commemorative for collectors and ceremonial presentation.
