Denier - Boleslaus I the Cruel

Boleslaus I earned his epithet by murdering his own brother Wenceslaus in 935 — the same Wenceslaus later venerated as Bohemia's patron saint. The deniers issued under his reign represent some of the earliest coinage struck in Bohemia, appearing as the duchy consolidated political control and began integrating into broader European trade networks. Cach 36 is among the more reliably attributed types in this difficult series, though die linkage across early Bohemian issues remains an ongoing problem for specialists.
