Denier Bracteate - Siemowit III Elder Płock or Kujawy mint

Siemowit III ruled Masovia for over fifty years, one of the longer reigns among the fragmented Piast dukes of the fourteenth century. His deniers and bracteates were struck across multiple mints as he consolidated territory, and attributing specific pieces to Płock versus the Kujawy mint remains contested — the documentary record for Masovian minor coinage of this period is thin enough that physical die-linkage studies carry more weight than archival evidence.

At 0.14 g, these bracteates were among the lightest silver coins in circulation in medieval Poland, handled daily in small transactions before being worn, clipped, or melted within years of issue.
