Denier - Eberhard I of Biburg

Eberhard I served as Archbishop of Salzburg during a period of intense friction between the Holy Roman Empire and the papacy, navigating the tail end of the Investiture Controversy while maintaining Salzburg's position as one of the most powerful ecclesiastical territories in the German-speaking world. He was a close ally of Bernard of Clairvaux and a committed supporter of the Cistercian reform movement, founding Raitenhaslach Abbey in 1143.

CNA A31 is among the earlier documented bracteate-influenced deniers attributable to the Salzburg mint under episcopal authority, predating the fuller bracteate transition that would dominate Alpine silver coinage by the late twelfth century.
