Billon antoninianus of Postumus, struck at the mint of Treveri (modern Trier) during his reign as emperor of the Gallic Empire. Obverse: Radiate bust of Postumus facing right, holding a club over the right shoulder; a lion’s skin draped over the left shoulder with strap across the heroically bare chest (Herculean type). Legend: POSTVMVS AVG Reverse: Pax standing left, holding a branch in her right hand and a sceptre in her left. Legend: PAX AVG This obverse type deliberately associates Postumus with Hercules, symbolizing strength and legitimacy, while the reverse emphasizes peace and stability under his rule. The Trier mint produced some of the finest and most iconographically ambitious issues of the Gallic Empire. Historical Context Postumus established the Gallic Empire in AD 260 amid the Crisis of the Third Century, ruling Gaul, Britain, and parts of Hispania independently from Rome. He maintained strong frontier defenses along the Rhine and promoted stability through effective administration. His coinage blends traditional Roman imagery with powerful personal symbolism, reinforcing his authority during a period of fragmentation.
