Drachm - Philip III Arrhidaios Abydos

Philip III Arrhidaios was the half-brother of Alexander the Great — intellectually disabled, possibly from a poisoning attempt in childhood, and entirely a figurehead king manipulated by the generals who carved up Alexander's empire after 323 BC. The Abydos mint, positioned at the strategically vital Hellespont crossing, continued striking in Alexander's name and types under the new regime, lending legitimacy through numismatic continuity even as the Diadochi tore the kingdom apart.

Philip III was murdered by Olympias in 317 BC, ending his six-year nominal reign.
