Pfennig - Ottokar II of Bohemia

Ottokar II acquired Austria in 1251 after the Babenberg line died out, ruling the duchy until Rudolf of Habsburg defeated and killed him at the Battle of Marchfeld in 1276 — one of the more consequential dynastic collisions of the medieval period. These pfennigs were struck across that quarter-century of Přemyslid control over Austrian lands, a tenure that left no permanent dynasty but a briefly enlarged Bohemian realm stretching from Silesia to the Adriatic.

CNA B 171 places this type within a well-documented sequence, though die studies have shown considerable variation across the issue's long production window.
