Denier elbląski - Sigismund I the Old Elbląg mint

Elbląg — a Prussian city that had transferred its allegiance to the Polish Crown in 1454 during the Thirteen Years' War — retained significant municipal privileges, including the right to strike its own coinage. These deniers were produced under that arrangement throughout the long reign of Sigismund I, with the city operating its mint under royal license rather than direct crown control. The Kopicki catalog distinguishes at least three die varieties across this span, reflecting decades of continuous small-denomination production serving local Baltic trade.
