Denier - Sobeslaus I

Sobeslaus I consolidated Přemyslid authority after defeating and killing the Holy Roman Emperor's candidate, Otto II of Olomouc, at the Battle of Chlumec in 1126 — a victory that secured his rule and reduced Bohemia's internal dynastic fragmentation for over a decade. The deniers struck under his name reflect that stabilized authority, though attribution within Bohemian bracteate-adjacent coinage of this period remains contested, and Cach 584 sits among a cluster of types whose precise mint assignment is still debated by Czech numismatic scholars.
