Denier - Otto I of Olomouc

Otto I ruled Olomouc as a Přemyslid appanage prince under the Bohemian duchy system, a arrangement that produced its own coinage but tied monetary output tightly to the political fortunes of Prague. His reign coincided with the turbulent years surrounding the Investiture Controversy, which fractured Bohemian ducal politics as sharply as it did the broader empire. Billon issues from Olomouc's Moravian mints during this period are notoriously inconsistent in alloy quality, reflecting the peripheral position of the Olomouc workshop relative to the better-documented Bohemian mints.
