1 Rouble

Tajikistan's first national currency issue came in 1994, replacing the Soviet and then Russian ruble that had continued circulating after independence. The Tajik ruble was always a transitional measure — the government introduced it knowing full well it would be short-lived, and indeed the entire series was replaced by the somoni in 2000. The 1 rouble sits at the lowest end of a series that was almost immediately devalued into irrelevance by hyperinflation; by the mid-1990s, denominations in the thousands were required for ordinary purchases.

Pick lists this as P#1, the foundation note of an independent monetary system built during an active civil war.
