Vladislaus II used his deniers partly as instruments of political signaling during a reign defined by his alliance with Frederick Barbarossa, whom he supported at the 1158 siege of Milan — a campaign that earned him the royal title he had long sought. Bohemian deniers of this period were struck under ducal, then royal authority, and the transition matters for attribution: Cach 593 falls within the ducal phase, before the elevation of 1158 formalized his kingship.
Czech denier production in this era relied on relatively impure silver, and die-cutting standards varied considerably between minting sessions.
