| Reverse description | A large, bold numeral '1' dominates the central field, rendered in a clean serif typeface. A naturalistic oak branch with a single lobed oak leaf extends diagonally from the upper left to the upper right, arching over the numeral. The denomination legend 'GROSZ' is inscribed in capital letters along the lower portion of the field beneath the numeral. The overall composition is clean and uncluttered, with the oak motif serving as a traditional symbol of Polish national identity. |

| Additional information |
Poland's shift to steel-core coinage for the grosz denominations was driven by a straightforward economic calculation: the rising cost of zinc and copper alloys had pushed the intrinsic metal value of the older brass pieces uncomfortably close to face value. The magnetic steel core resolved that problem permanently. Fisher's classic concern about Gresham's Law — bad money driving out good — was precisely what Warsaw's monetary planners were avoiding.
