50 Paisa - Birendra Bir Bikram

Nepal's shift to copper-nickel coinage in the early 1970s coincided with a broader decimalization push that had been reorganizing the subcontinent's monetary systems since Indian independence. The 50 Paisa issued under Birendra's reign spans a politically turbulent stretch — he inherited the throne in 1972 following Mahendra's death, ruling under the Panchayat system, a partyless political structure that concentrated power in the crown and was eventually dismantled by popular movement in 1990.

KM#821 runs across multiple years without major variety documentation, though date collectors target the early Bikram Sambat issues for relative scarcity.
