250 Rupees - Birendra Bir Bikram 10th Anniversary of Reign

Birendra ascended the throne in January 1972 following the death of his father Mahendra, inheriting a kingdom still absorbing the shock of its first experiment with political parties — an experiment Mahendra had personally dismantled in 1960. By 1981, the tenth anniversary fell during a period of cautious political liberalization: Birendra had held a referendum the previous year in which Nepalis narrowly voted to retain the partyless Panchayat system, a result many observers disputed. This coin was struck against that uneasy backdrop.

The .925 silver specification and 28.28g weight mirror the Commonwealth commemorative standard widely adopted in the late 1970s, suggesting the blanks or specifications were likely sourced through the Franklin Mint or a comparable contract minting arrangement, as Nepal had no domestic silver striking capacity at the time.
