20 Groszy One Hundred Years of the Zloty

The Polish złoty was reintroduced in 1924 under finance minister Władysław Grabski, replacing the hyperinflation-wrecked Polish mark at a rate of 1,800,000 marks to one złoty — one of the more dramatic currency resets of the interwar period. The name itself was not new; the złoty had circulated in various forms since the 15th century, making the 1924 relaunch a deliberate act of monetary continuity as much as reform.

This 20 groszy denomination places the coin within the fractional structure Grabski's reform established in 1924, retained through subsequent monetary reorganizations including the communist-era redenomination of 1950 and the post-hyperinflation redenomination of 1995.
