Denier Bracteate - Henry I of Harburg

Henry I of Harburg served as Archbishop of Mainz during a period when the archbishopric was deeply entangled in the investiture struggles still reverberating after the Concordat of Worms. Bracteates of this issue were struck at a time when Mainz held primacy among German ecclesiastical mints, and the thinness of the flan — a structural necessity of bracteate production, not a deficiency — made these coins notoriously fragile in circulation. Surviving examples with full, uncracked flans are genuinely scarce.
