Denier - Otto I of Olomouc

Otto I ruled Olomouc as an appanage duchy under the Přemyslid system, which fragmented Moravia into separate principalities from the mid-eleventh century onward. His deniers are among the earliest attributable coins from the Olomouc mint, and Cach 378 sits in a series where die-cutting quality varies considerably — the Bohemian moneyers of this period worked with limited technical consistency, and even within a single type, letter forms and flan preparation differ enough to complicate attribution.
