Denier - Sobeslaus I

Sobeslaus I consolidated Bohemian ducal power after defeating the German-backed claimant Otto II of Olomouc at the Battle of Chlumec in 1126, a victory that secured his reign and removed the principal threat of Přemyslid internal fragmentation for a generation. The billon deniers struck under his authority reflect a mint operating with reasonable consistency through an unusually stable fifteen-year rule.

Cach 582 is among the better-documented varieties of his coinage, cross-referenced in both Šmerda and Donebauer without significant attribution disputes — a relative rarity for Bohemian bracteate-adjacent issues of this period.
