The Warsaw Mint during the Second Polish Republic minted a series of beautiful plaques commemorating mainly important figures of the era, which today constitute a very interesting but difficult to complete collector's section. She minted them mainly in two versions (small ~3x4 cm and large ~6x9 cm). In addition to the two standard sizes, she also made large-format castings for special/private orders. Today a huge rarity due to their unitary nature.
The mintage of this one in his study"Plakietta Mint of Warsaw" was determined by Jacek Strzałkowski to be about 3 pieces!
