5 Rupees - Birendra Bir Bikram IYY

The IYY designation marks this as part of the International Youth Year series — a UN-coordinated global initiative in 1985 that prompted dozens of nations to issue commemorative coins, most of which saw negligible circulation and ended up in mint sets. Nepal's participation under King Birendra aligned with a broader effort to project modernizing credentials during a period when the Panchayat political system was facing growing internal criticism.
