Denier - Boleslaus I the Cruel

Boleslaus I earned his epithet by ordering the murder of his brother Wenceslaus in 935 — the same Wenceslaus later canonized as Bohemia's patron saint. His subsequent 37-year reign was spent consolidating Přemyslid control over a fragmented territory, and coinage was part of that project. These early Bohemian deniers are among the first struck coins attributable to the region with any confidence, predating a coherent mint infrastructure by decades.

Cach 23 is among the rarer attributed types of his reign, with surviving examples spread thinly across Czech and German institutional collections.
