1 Pfennig - Ottokar II of Bohemia

Ottokar II acquired the Duchy of Austria in 1251 through his marriage to Margaret of Babenberg, inheriting a territory whose previous ruling house had just died out with Frederick II in 1246. His pfennig coinage belongs to the broader Vienna mint tradition of thin, bracteate-style silver, though these are struck on both faces — the so-called Dünnpfennige that dominated Alpine monetary circulation through the thirteenth century. Ottokar's Austrian tenure ended abruptly in 1276 when Rudolf of Habsburg used a legal pretext to strip him of the duchy entirely.
