Denier Bracteate - Mieszko III the Old Gniezno or Kalisz mint

Mieszko III ruled Greater Poland twice — expelled by his own nobility in 1177, he spent decades in political exile before reclaiming his position, dying in office in 1202. The bracteate format, a single-sided coin struck on a thin flan, was characteristic of Polish minting practice in the twelfth century, where the technical demands of double-sided striking were bypassed in favor of speed and simplicity. Gniezno and Kalisz both functioned as ducal administrative centers, and attribution to one mint over the other remains unresolved for most Mieszko III issues.

Kopicki 106 is among the more frequently cited references for this ruler, though die variation within the type is considerable.
