Stater - Philip III Arrhidaeus Abydos

Philip III Arrhidaeus was Alexander the Great's half-brother — intellectually disabled, almost certainly exploited as a political puppet by rival factions within the Macedonian court from the moment Alexander died in Babylon. The Abydos mint, controlling a strategically critical crossing point on the Hellespont, continued striking in the established Alexandrine tradition under his nominal authority. His reign ended violently in 317 BC when Olympias, Alexander's mother, had him executed.

Price P31 is among the rarer Abydos attributions in this series, the mint identified through careful die linkage rather than any explicit mark.
