1 Solot / 1/2 Att / 1⁄16 Fuang - Rama V

Rama V — Chulalongkorn — introduced this copper series as part of a sweeping modernization of the Siamese monetary system, replacing the older bullet (pod duang) coinage that had circulated for centuries. The reform was as much diplomatic as economic: standardized, machine-struck coin denominations signaled to European colonial powers that Siam operated a recognizable monetary order, a calculation that likely contributed to its survival as the only Southeast Asian nation to avoid formal colonization.

The fractional att denominations saw heavy circulation in provincial markets and are rarely found without wear.
