10 Baht - Rama VIII Series 7, Type I watermark constitution

Thailand's first modern banknotes printed by Thomas De La Rue were ordered during WWII but could not be delivered — the series reached circulation only after the Japanese occupation ended in 1945. The Type I watermark, showing the constitution monument, distinguishes this issue from the later Type II chakra watermark variants on otherwise identical notes.

Rama VIII — King Ananda Mahidol — died in June 1946 under circumstances that remain officially unresolved. Notes bearing his royal cipher were quietly withdrawn and replaced, making surviving circulated examples rarer than the print run alone would suggest.
