Antoninianus - Postumus VICTORIA AVG

Postumus founded the breakaway Gallic Empire in 260 AD after defeating Saloninus, the son of Gallienus, at Cologne — a political rupture that left Rome effectively governing only Italy and the East while Postumus controlled the Rhine frontier, Britain, and Hispania for nearly a decade. His VICTORIA issues were not triumphal vanity; they marked real military work, specifically the containment of Alemanni and Frankish incursions that the central Roman government had repeatedly failed to stop. The Gallic mints, likely operating at Cologne and possibly Trier, produced billon of noticeably variable silver content across his reign, with earliest strikes generally the richest.
