Pfennig - Ottokar III or Ottokar IV

Styrian coinage of the late 12th century sits in one of the more administratively tangled periods of the duchy's history. Ottokar III died in 1164, leaving Styria to his son Ottokar IV, who suffered from an unnamed chronic illness and ultimately signed the Georgenberg Pact in 1186 — ceding Styria to the Babenbergs of Austria upon his death, which came in 1192. Attribution of pfennigs to one Ottokar or the other within this window remains genuinely unresolved, and CNA#B93 reflects that uncertainty honestly rather than forcing a false assignment.
