Casimir III Half-Grosz

The Half-Grosz of Casimir III was struck with a fineness that approached 90% silver, a rarity for Polish coins of the era and a testament to his monetary reforms. This helped curb inflation in a kingdom still reeling from wars and fragmentation. The coin itself is diminutive, typically weighing under a gram, and bears the king's name or a simple cross on one side.

Most specimens I've examined show signs of wear from heavy circulation, suggesting they were used in everyday transactions rather than hoarded. Mintage figures are murky; records from that period often perished in later conflicts. As for design variations, they depended on the mint—likely Krakow or other royal centers—but exact dies remain a mystery.

One oddity: these coins could easily slip through fingers, much like promises in a medieval treaty.
