50 Zlotych

This note belongs to the first postwar Polish issue, produced as the communist-backed Provisional Government was consolidating control and the prewar Bank of Poland had been effectively supplanted. The series was designed and printed under difficult conditions — Poland's own printing infrastructure had been devastated, and early postwar notes were produced with relatively modest security specifications, the single watermark being the primary anti-counterfeiting measure.

Circulation wear on surviving examples tends to concentrate along the horizontal fold lines, reflecting the folded-wallet habits common in the austerity years before the 1950 currency reform, which wiped out this series entirely at a punishing 100:3 conversion rate against the new złoty.
