Denier Bracteate - John I

Hersfeld Abbey held imperial immediacy — answerable to the emperor alone, not any intervening bishop — and that autonomy extended to the mint. John I's abbacy coincided with the turbulent dual-kingship period between Philip of Swabia and Otto IV, during which ecclesiastical mints across the Rhineland and Thuringia operated with unusual independence as central authority fragmented. The bracteate fabric itself, a technology almost exclusively German, required hammering silver thin enough that the design struck through as a mirror image on the reverse.

Berger's census for this type remains small.
