1 Baht - Rama III Prasat-Chakra-Unalom

Rama III inherited a kingdom still defining its relationship with expanding European colonial powers, and his reign saw deliberate economic consolidation — including tighter control over the bullet coinage that had circulated in Siam for centuries. The Prasat-Chakra-Unalom combination of marks identifies this piece as issued under his authority, punched into the pre-formed silver slug by royal minters at Bangkok.

Bullet coins of this type were produced without dies in the Western sense; the silver was folded and struck into shape, then authenticated with hot punches. Genuine examples carry tool marks consistent with hand production, and no two are identical.
