Denier - Boleslaus III Wrymouth Kraków mint

Boleslaus III spent much of his reign in near-continuous warfare — against the Holy Roman Empire, Pomerania, and his own half-brother Zbigniew, whom he had blinded and expelled in 1112. The Kraków mint operated through all of it, producing bracteate-style deniers of notably low silver content by this period, a reflection of general Central European monetary debasement rather than any specific Polish policy.

Kop#44 is among the thinner and more fragile of the Polish early medieval series. Flan cracks are endemic to the type.
