Denier - Boleslaus I the Cruel

Boleslaus I earned his epithet by murdering his brother Wenceslaus in 935 — the same Wenceslaus later canonized and immortalized in carol — then ruled Bohemia for nearly four decades, expanding its territory aggressively into Moravia, Silesia, and parts of Poland. His deniers represent the earliest phase of Bohemian coinage, struck at a moment when the duchy was consolidating enough political and economic infrastructure to mint at all. The Cach 25 attribution places this among the foundational types of the series.
