Denier - Philippus I

Philip II of Aragon — the same Philip who launched the Armada, presided over the Dutch Revolt, and managed the flood of American silver that was simultaneously enriching and destabilizing Castile — issued this small billon piece under Aragonese monetary law, which remained deliberately separate from Castilian coinage authority throughout his reign. The Crown of Aragon retained its own mint jurisdictions and fiscal autonomy even as Philip consolidated power elsewhere, and these deniers reflect that structural resistance to centralization.

Cal#904 places this within a well-documented series, though surviving examples in attributable condition are scarcer than the long reign span might suggest.
