1 Fuang - Rama IV

Rama IV — Mongkut — had spent 27 years as a Buddhist monk before ascending the throne in 1851, and his reign marked Thailand's first sustained engagement with Western-style monetary reform. The fuang was a traditional Siamese fractional unit, and these early silver issues of his reign still reflect the old bullet-coin tradition being pressed into more recognizable struck form for foreign trade purposes.

C#124 places this within the early transitional coinage before the 1860 royal mint reforms standardized production.
