1 Dam - Jaya Prakash Malla

Jaya Prakash Malla ruled Kathmandu during one of the most turbulent stretches in Newar political history, a period of fractured alliances and near-constant warfare among the three rival Malla kingdoms of the valley. His reign would ultimately end in 1768 when Prithvi Narayan Shah's Gorkha forces swept through and extinguished the Malla dynasties entirely. At one-twentieth of a mohar, the dam denomination was the smallest practical silver unit in circulation — producing it at this scale required exceptional die-cutting skill, and surviving examples almost universally show some degree of weak or off-center striking simply due to the mechanical difficulty of controlling such a tiny flan.
