Dinero - Alfonso VII Leon

Alfonso VII ruled a unified Castile and León following his mother Urraca's turbulent reign, and was crowned "Emperor of All Spain" at León in 1135 — a title with real political weight, used to assert primacy over the other Iberian Christian kingdoms. Billon coinage of this reign circulated heavily in a frontier economy driven by tribute payments, ransoms, and the constant commercial churn of the Reconquista border zones.

AB#55 is among the earlier medieval Iberian types catalogued by Álvarez Burgos, and attribution can be complicated by the overlapping issues of Castile and León before and after Alfonso's unification of the crowns in 1126.
