Denier Bracteate - Mieszko III the Old Gniezno mint

Mieszko III ruled Greater Poland twice — expelled by his own nobles in 1177, he clawed back power repeatedly over the following decades, making the precise attribution of his bracteate issues to specific sub-periods genuinely difficult. Gniezno, as the ecclesiastical capital of the Polish church and the site of the first Polish coronation in 1025, was a natural minting seat for a duke constantly needing to assert dynastic legitimacy against rival Piast claimants.

At 0.14 g, these pieces were struck on foil-thin flans, and the bracteate technique itself — a single-sided impression — was adopted across northern-central Europe during the 12th century partly because it demanded less silver per coin.
