1 Paisa - Mahendra Bir Bikram

Nepal's transition to decimal coinage in 1961 under King Mahendra displaced the old anna-based system and required entirely new denominations to be struck in quantity for everyday transactions. The paisa — now defined as one-hundredth of a rupee — needed to reach rural markets that had functioned on barter and older fractional coins for generations. This brass issue was part of that initial decimal rollout, produced across just two years before the series was revised.
