1 Grosz Trial Strike Brass

Poland's 1949 coinage reform was a deliberate instrument of Stalinist economic consolidation, replacing the wartime and immediate postwar currency with a new series explicitly tied to the People's Republic. Trial strikes in brass for this denomination were part of broader material testing conducted before the aluminum composition was selected for production — the final circulating grosz coins emerged far lighter and cheaper to produce, suited to a command economy prioritizing industrial metal allocation over coin longevity.
