Denier Bracteate - Mieszko the Younger Kalisz mint

Mieszko the Younger's tenure as duke was turbulent even by the fractious standards of Piast dynastic politics. He held Kalisz intermittently, squeezed between competing brothers and the constant threat of expulsion — which came more than once. The Kalisz mint operated under these unstable conditions, making coherent attribution difficult and confirmed issues rare.

Bracteates of this type survive in small numbers, their thin fabric making intact examples genuinely scarce. Kopicki 138 remains the standard reference, though the attribution to Mieszko the Younger specifically rests on stylistic and hoard evidence rather than documentary confirmation.
