Denier Bracteate - Leszek the White Kraków mint

Leszek the White held Kraków intermittently — his tenure was twice interrupted by rivals, including a forced exile following the 1210 congress of Borzykowa and ongoing pressure from Mieszko III's faction. Bracteates of this fragile, single-sided type were the dominant small denomination in Piast Poland throughout the late 12th and early 13th centuries, struck so thin that even moderate handling destroys them. The unlisted Kop# reference reflects how poorly documented individual Kraków bracteate dies remain — many survive only in hoards, where the stacking pressure alone causes fusing.
