Denier - Ulrich

Ulrich (Oldřich) of Bohemia ruled during one of the Přemyslid dynasty's most turbulent stretches — he was deposed twice, blinded his own brother Jaromír to consolidate power, and spent years navigating shifting allegiances between the Holy Roman Empire and the Polish Piasts under Bolesław I. Deniers of his reign are poorly documented in contemporary sources, and Cach's cataloguing remains the primary reference framework for distinguishing his issues from those of his predecessors.

The nearly quarter-century attribution window for this type reflects genuine uncertainty about sequential die production at the Bohemian mints.
