| Reverse description | A royal crown occupies the central field, depicted with multiple fleurs or points along the upper band and visible cross ornamentation on the circlet, all rendered in a rough, debased style consistent with a contemporary counterfeit struck from unofficial dies. The design is enclosed within a beaded inner circle, with a partial, mostly illegible Latin legend in the outer field. The weak, irregular strike and uneven flan confirm the non-official nature of this piece. |

| Additional information |
Contemporary counterfeits of Casimir IV's half-groschen are well documented and circulated freely during his reign (1447–1492), exploiting the coin's low intrinsic value and the kingdom's limited capacity to police its monetary supply across Silesia, Prussia, and the Lithuanian borderlands. The billon content of official issues was itself debased enough that forgers needed only modest equipment to produce plausible copies.
Weight typically runs well below official specification — this example at 0.70g is consistent with the lighter flans favored by counterfeiters to maximize output per unit of metal.
