1 Pfennig - Austrian Interregnum

Frederick II of Austria died at the Battle of the Leitha in June 1246, leaving no direct heirs and extinguishing the Babenberg dynasty after nearly three centuries. The duchy fell into a succession crisis that drew in claimants from Bohemia, Hungary, and the papacy before the Habsburgs eventually consolidated control. Coins struck in this interregnum period were produced without clear ducal authority, likely by ministeriales or mint officials continuing operations by institutional inertia rather than by any sovereign directive.
