1 Prague Groschen Counterstamped

Fritzlar, a small ecclesiastical city in Hesse under the jurisdiction of the Archbishop of Mainz, counterstamped foreign silver as a practical solution to chronic shortages of locally-authorized coinage. The Prague Groschen — struck in Bohemia and widely circulated across central Europe — was among the most common silver coins in the region, making it the obvious host for municipal validation marks.

The counterstamp authorized the coin for local circulation at an officially sanctioned rate, a common practice among smaller German cities that lacked full minting rights. Krusy F 4,1 remains thinly documented in terms of surviving population.
