20 000 Zlotys Casimir IV Jagiellon

Casimir IV Jagiellon ruled Poland-Lithuania from 1447 to 1492, presiding over the Thirteen Years' War against the Teutonic Knights that ended with the Second Peace of Toruń in 1466 — forcing the Order to cede Royal Prussia and acknowledge Polish suzerainty. The 1993 issue falls within Poland's post-communist commemorative series, struck as the country was still rebuilding its monetary institutions following the 1990 redenomination that wiped four zeros off the old złoty.

The 20,000-złoty face value itself was already an artifact of inflation; by 1995, Poland redenominated again, replacing 10,000 old złotych with one new złoty.
