| Additional information |
The bullet coinage tradition — pod duang — had served Siam for centuries, but by the 1860s Rama IV was acutely aware that Western trading partners viewed the lumpen, unmarked pieces with suspicion. The flat coinage program he initiated represented a direct diplomatic calculation: Siam needed to look like a modern state to avoid the fate of its neighbors. The Tamlueng denomination sat at four Baht, making this one of the heaviest silver pieces in the series.
Production relied on imported machinery, and early striking quality was inconsistent enough that examples vary noticeably in sharpness across the die field.
