Denier Bracteate protekcyjny - Boleslaus III Wrymouth Kraków or Gniezno mint

Bolesław III Krzywousty — Wrymouth — issued these thin single-sided bracteates during a reign defined by near-constant military campaigning: wars against Pomerania, Bohemia, and the Holy Roman Empire consumed both treasury and administrative energy. The protective bracteate type takes its name from the cross motif believed to carry apotropaic function, a convention borrowed from German ecclesiastical minting practice that had penetrated Polish coinage by the early twelfth century.

Attribution to either Kraków or Gniezno remains unresolved. Both mints were active under Krzywousty, and die evidence alone has not settled the question.
