Denier - Engelbert I of Berg

Engelbert I served as Archbishop of Cologne from 1216 until his murder in 1225 — ambushed and killed by his cousin, Count Frederick of Isenberg, in a dispute over the administration of the Essen convent's estates. He was canonized in 1226, barely a year after his death, and the archbishopric moved quickly to promote his cult. Deniers struck during his tenure circulated across a region where the archbishops of Cologne wielded secular authority as princes of the empire alongside their ecclesiastical role.

Häv. 621 places this type within the broader Cologne bracteate and denier sequence; Bonhoff 1590 confirms attribution.
