20 000 Zlotys

By 1989, Polish inflation was accelerating toward hyperinflation — the 20,000 złoty note, a denomination unthinkable a decade earlier, was already losing purchasing power faster than it could be distributed. The following year, 500,000 and 1,000,000 złoty notes entered circulation. This entire series was eventually rendered obsolete by the 1995 redenomination, which lopped four zeros off the currency and introduced the "new złoty" at 10,000 old to one.

The PWPW Warsaw printing attribution here is straightforward — unlike several earlier NBP issues that relied on foreign security printers, by this period domestic production was standard.
