1 Salung, Ayutthaya

The salung was a fractional unit of the tical (baht), and Ayutthayan bullet coins of this type were produced by folding and hammering silver into a globular form — a technique that changed remarkably little across four centuries of the kingdom's existence. Authentication relies heavily on the purity and granular surface texture of the silver rather than die work, since these were struck by hand without engraved dies in any conventional sense.
