1 Salung - Rama III Luk Sorn

The Luk Sorn ("bullet coin") tradition in Siam predates Western-style coinage by centuries, with these hand-formed silver pieces produced by rolling a measured blank into a tight coil and punch-stamping royal marks into the metal. Rama III, who died in 1851 and famously refused European diplomatic overtures that would have accelerated Siamese modernization, issued these through his reign without mechanized minting infrastructure of any kind.

Successor Rama IV commissioned the kingdom's first coin press from Britain shortly after taking the throne — effectively rendering this type obsolete within years of its last striking.
