1 Prague Groschen Counterstamped

Auerbach in the Upper Palatinate was among several small German towns that resorted to counterstamping foreign silver in the later fourteenth century when locally-struck coinage was either unavailable or insufficient. The Prague Groschen, struck under the Bohemian crown, circulated widely across central Europe and frequently served as the base coin for such municipal validations. The counterstamp functioned as a guarantee of local acceptance rather than a revaluation.

Krusý documents this type sparsely, and surviving examples are rare. 1378 — the year of Charles IV's death — marked a period of political transition that may have prompted renewed attention to currency control at the municipal level.
