16000 Baht 80th Birthday of HM Queen Sirikit

Queen Sirikit turned 80 in August 2012, but Thai royal commemorative gold issues frequently see delayed striking and official release — this 2013 issue follows that pattern exactly. The Royal Thai Mint produces these high-denomination commemoratives in strictly limited quantities, intended for presentation rather than commerce, and the 16,000 baht face value places it firmly beyond any practical circulation function.
