Tetradrachm - Philip I ΔΗΜΑΡΧ ΕΞΟΥϹΙΑϹ ΥΠΑ ΤΟ Δ, ΑΝΤΙΟΧΙΑ, S C

Philip I struck this issue at Antioch during 248 AD, the year Rome celebrated its thousandth anniversary — the Ludi Saeculares — an event Philip organized with considerable political investment, minting a substantial commemorative series in Rome while the eastern provincial mints continued their own outputs largely uninterrupted. The Antioch billon tetradrachms of this period are notable for the dramatically debased silver content inherited from decades of crisis-era debasement, rendering them functionally a token coinage despite retaining the tetradrachm denomination.

Philip was dead within a year, killed at Verona fighting the usurper Decius.
