1 Baht - Rama I

Bullet coinage of this type — tical in the Thai monetary tradition — was produced by hand, with each piece formed by hammering a roughly spherical silver blank and then applying countermarks. No two are identical in shape. Rama I, who founded the Chakri dynasty in 1782 after the fall of Ayutthaya and the chaos of the Thonburi interregnum, inherited a monetary system that had operated on these same hammered forms for centuries and saw no reason to abandon it.

The dynasty's countermarks on this series authenticated royal silver at a moment when Siam was aggressively rebuilding trade networks with China and regional neighbors. That commercial urgency made consistent silver weight — not consistent form — the priority.
