1 Mohar - Vishnu Malla

Patan — also known as Lalitpur — was one of three rival Newar kingdoms occupying the Kathmandu Valley, and its rulers maintained independent coinage traditions even as Mughal commercial pressure reshaped currency standards across the subcontinent. Vishnu Malla reigned during a period of intensifying competition between Patan, Kathmandu, and Bhaktapur, a rivalry that would end definitively in 1768 when Prithvi Narayan Shah's Gorkha forces unified the valley by conquest. The mohar was the backbone of Nepal's silver currency system, with its weight standard loosely tied to the tola, though individual kingdoms adjusted fineness and weight to suit local treasury needs.

KM#400 is among the later issues of Patan's independent mint — within four decades of this coin's production, the city's sovereign coinage would cease entirely.
