Denier Bracteate - Mieszko III the Old Gniezno or Kalisz mint

Mieszko III ruled Greater Poland twice — expelled by his own nobles in 1177, he spent decades maneuvering for restoration before finally reclaiming Kraków in 1199. The bracteate coinage attributed to his administration reflects the fragmented minting reality of the Piast duchies, where episcopal and ducal workshops in Gniezno and Kalisz operated with considerable independence. Kop#127 sits within a contested attribution sequence; some specialists assign identical or near-identical dies to his son Bolesław.

The bracteate format itself arrived in Polish lands from German influence in the mid-twelfth century, displacing the older two-sided denier.
