Denier - Jaromir

Jaromír ruled Bohemia three separate times — an unusual political fact for the period — each reign interrupted by the machinations of his brother Oldřich and the pressures of Polish occupation under Bolesław I Chrobry, who held Bohemia briefly around 1003–1004. Coinage attribution across Jaromír's fragmented reigns remains genuinely difficult, and Cach 237 sits in a contested zone where die evidence and political chronology do not always align neatly.

The denier series of early Bohemia was heavily influenced by Bavarian and Saxon prototypes arriving through trade and political alliance rather than any indigenous minting tradition.
