1 Rupee - Tribhuvana Bir Bikram

Nepal's silver rupee coinage of this period was struck under Tribhuvan, the king who would later orchestrate the 1950–51 revolution that overthrew the century-old Rana oligarchy — a hereditary prime ministerial dynasty that had reduced the monarchy to near-ceremonial status. During the years this coin was minted, Tribhuvan himself was effectively a prisoner of the Rana court, his movements monitored and his authority nominal. The coins bore his name and portrait while real power resided entirely elsewhere.

In November 1950, Tribhuvan famously sought asylum in the Indian embassy in Kathmandu, triggering the political crisis that ended Rana rule entirely.
