Obolo - Pedro I

Pedro I of Aragon and Pamplona spent virtually his entire reign at war, campaigning relentlessly against the taifa kingdoms in the upper Ebro valley. His capture of Huesca in 1096 — which became his capital — and the grinding siege of Zaragoza that consumed his later years left little administrative bandwidth for monetary reform. The billon coinage of this period reflects that: minimal silver content, inconsistent striking, production subordinated entirely to the demands of a permanent war footing.
