Pfennig - Berthold III and Berthold IV Windischgrätz

The Counts of Andechs reached the peak of their territorial ambitions in the late twelfth century, acquiring the Duchy of Merania in 1180 after Duke Henry the Lion's fall from imperial favor left a political vacuum across the eastern Alpine frontier. Berthold III and his son Berthold IV co-issued this pfennig during a period when the dynasty was aggressively consolidating control over mint rights across their scattered holdings in Styria, Carinthia, and Istria.

Windischgrätz — modern Slovenj Gradec — was one of several secondary minting sites the Andechs operated simultaneously, a deliberate strategy to assert jurisdictional presence rather than meet any particular commercial demand.
