50 Groszy One Hundred Years of the Zloty

Poland's interwar zloty was introduced in 1924 under finance minister Władysław Grabski as part of an aggressive stabilization program that replaced the badly inflated Polish mark at a rate of 1,800,000 marks per zloty. The reform worked — briefly. By the early 1930s, global depression pressure and deflation policy had made the zloty one of the more punishing currencies in Central Europe for domestic industry.

This piece is one of several denominations struck by Mennica Polska for the centenary series, with the .900 gold composition echoing the fineness of certain interwar bullion-adjacent coinage rather than the mint's more common modern proof standards.
