Denier - Boleslaus II the Pious

Boleslaus II consolidated Bohemian Christianity with unusual aggression — it was during his reign that the Prague bishopric was established in 973, separating Bohemia ecclesiastically from the German diocese of Regensburg. Coinage under his rule borrowed heavily from Carolingian and Ottonian denier prototypes, reflecting both political dependence on and rivalry with the Holy Roman Empire.

Cach 1019 is among the more precisely attributed varieties in the Boleslaus II series, though die linkage studies have shown considerable overlap between issues across his three-decade reign, making tight date ranges within the 967–999 bracket difficult to sustain without hoard context.
