Denier Bracteate elbląski - Casimir IV Jagiellon Elbląg mint

Casimir IV's reign saw the prolonged struggle of the Thirteen Years' War against the Teutonic Knights, and Elbląg — captured by the Prussian Confederation and handed to the Polish crown in 1454 — became one of the key mints operating under the new political arrangement. These bracteates served the low-denomination needs of a region transitioning from Teutonic to Polish monetary administration, struck on wafer-thin flans from a single die, a technique by then considered archaic in most of western Europe but maintained in the region for small-change production well into the late fifteenth century.
