500 Zlotys Defensive War of Poland

Issued in the final months of communist Poland, this coin commemorates the 50th anniversary of the September 1939 campaign — the five-week defense against simultaneous German and Soviet invasion that ended with Poland's occupation and partition. The timing is quietly significant: by mid-1989, the Round Table Agreements had already transferred substantial power to Solidarity, and the communist government authorizing this issue would be out of office within months.
