10 Satang - Rama VIII thick planchet

Thailand's tin coinage of 1944 was a direct consequence of wartime metal shortages — with Japanese occupation forces having monopolized strategic metals, the Thai government turned to tin, one of the country's own abundant domestic resources. Two distinct planchet thicknesses were produced within the same issue year, the thicker variety carrying notably more mass without any change in diameter, suggesting a mid-run adjustment to the blanking process rather than a planned specification change.

Rama VIII — Ananda Mahidol — was only sixteen and studying in Switzerland when these coins circulated in his name.
