Osca — modern Huesca in northeastern Spain — was a significant Iberian mint during the late Republican period, producing silver coinage that circulated widely across the Ebro valley. This issue dates to the turbulent years following Julius Caesar's assassination, when competing Roman factions were still contesting control of the Iberian provinces. The city had long operated under Roman administrative influence while maintaining a degree of civic minting authority, a hybrid arrangement that produced coins blending Iberian and Roman conventions.
