50 Paisa - Tribhuvana Bir Bikram

Nepal's billon coinage of this period emerged from a monetary system that was deliberately insular — the country had resisted foreign financial influence well into the twentieth century, and domestic silver alloy coins remained the backbone of everyday exchange long after neighboring British India had shifted toward cupro-nickel. Tribhuvana Bir Bikram was king during one of the most politically volatile stretches in modern Nepali history; in 1950, just two years after this coin was struck, he would flee to the Indian embassy in Kathmandu and then to India itself, triggering the revolution that dismantled the century-long Rana oligarchy.

The .333 fine silver content places this squarely in Nepal's transitional billon series, below the higher-silver issues of earlier reigns.
