2 Zlotys Polonia Warszawa

The "Polonia Warszawa" 2 Złote commemorates the Polish football club founded in 1911, issuing this coin on the centenary of that founding. Polonia Warszawa is one of the oldest clubs in Poland, though it has spent much of its modern history outside the top flight — a fact that makes a national bank commemorative feel slightly incongruous. The Nordic gold format, an aluminum-bronze alloy used across Poland's long-running municipal and cultural commemorative series, had by 2011 produced well over 500 distinct circulating collector pieces.
