Denier poznański - Casimir III the Great Poznań mint

Casimir III inherited a fragmented monetary system and spent much of his reign attempting to rationalize it — the Poznań mint was one of several regional operations he brought under tighter crown control, part of the same administrative overhaul that produced his famous legal codifications of 1346–47. These deniers circulated in a Poland actively rebuilding from Teutonic depredations and the chaos of the Piast succession crisis, meaning many specimens entered the ground as hoards rather than wearing through normal trade. Kop. 7937 is among the lighter and smaller products of the Poznań operation, whose output varied noticeably from the Kraków issues of the same reign.
