Stater - Philip III Arrhidaeus Pella

Philip III Arrhidaeus was the half-brother of Alexander the Great — intellectually disabled, almost certainly exploited as a figurehead by competing factions of the diadochi — and the coins struck in his name at Pella continued the Philip II gold stater types almost without interruption. The design was a deliberate act of political continuity, not artistic inertia. Whoever controlled Philip III controlled the legitimate face of Macedonian authority, and the coinage broadcast that claim.

He was murdered in 317 BC on the orders of Olympias, Alexander's mother, making the later dates in this emission posthumous issues struck by regents consolidating power after his death.
