Second Republic 1 Grosz

The 1 Grosz coin from Poland's Second Republic often featured an eagle design that varied slightly year by year, as engravers tweaked it amid ongoing border disputes.

This reflected the hasty minting process after World War I, when Poland restarted its coinage with whatever tools and metals were at hand. Some planchets were likely recycled from pre-war stocks, a practical if unglamorous choice. The coin itself was small, bronze in the early years, and intended for everyday use in a battered economy.

Mintage figures for specific years are spotty; records from the Warsaw Mint weren't always kept meticulously during that turmoil. As for myths about hidden treasures, I've yet to find one worth the hype—most turn up in old jars.

One oddity: the 1938 version has a slightly off-center strike in some cases, like a typist's error in a hurry.
