50 Karbovantsiv

Ukraine's first post-Soviet banknote series, introduced in 1992 after independence, was printed by the Canadian Bank Note Company in Ottawa — an interesting early partnership for a newly sovereign state scrambling to establish a functional currency before the hryvnia could be readied. The karbovanets itself was technically a transitional coupon currency, not a permanent monetary unit, and the entire series was demonetized by September 1996 when the hryvnia finally replaced it at a rate of 100,000 karbovantsiv to one hryvnia.

That ratio tells the inflation story bluntly. Hyperinflation through 1993–94 rendered small denominations useless almost immediately after issue.
