Denier - Ottokar I and Wenceslaus I

These deniers occupy a precise administrative moment: the co-regency period when the aging Ottokar I, having secured Bohemia's hereditary royal status through the Golden Bull of Sicily in 1212, began transferring effective governance to his son Wenceslaus before his death in December 1230. Cach 701 is among the few coin types explicitly attributable to this transitional joint authority rather than to either ruler alone.

The type's two-year window makes survivors genuinely scarce by Bohemian denier standards.
