800 Baht - Rama IX Princess Bejaratana Rajasuda

Princess Bejaratana Rajasuda, the only child of King Vajiravudh (Rama VI), spent decades as a senior member of the royal family without the political prominence her lineage might suggest — a quiet position that reflected the dramatic shift in the Thai monarchy's constitutional role following the 1932 revolution, which ended absolute rule just years after her birth. This coin marks her 2009 centenary, issued the year before her death at age 101.
