50 000 Karbovantsiv

Ukraine's early post-Soviet hyperinflation was severe enough that the karbovanets — itself a temporary currency introduced in 1992 to replace Soviet rubles — required denominations in the tens of thousands within a year of issue. The 50,000 karbovantsiv note belongs to that compressed, almost panicked phase of monetary history, when the National Bank was issuing new high-denomination paper faster than public confidence could keep pace. Annual inflation peaked above 10,000 percent in 1993.

The karbovanets was withdrawn entirely in September 1996, replaced by the hryvnia at 100,000 to 1. Most circulated examples absorbed considerable wear in a very short window.
