Tetradrachm - Philip III In the name of Alexander III, Tarsos

Struck at Tarsos under Philip III Arrhidaeus, Alexander's half-brother who was proclaimed king immediately after Alexander's death in Babylon in 323 BC — largely because he was present and the generals needed a figurehead. Arrhidaeus had been kept deliberately obscure during Alexander's lifetime, possibly due to a cognitive disability, and real power was exercised by the regent Perdiccas. The Tarsos mint continued producing coinage in Alexander's name throughout this period, a deliberate political signal of continuity during the wars of the Diadochi. Philip III was murdered on Olympias's orders in 317 BC, ending the regency fiction.
