Drachm - Philip III In the name of Alexander III; Babylon

Philip III Arrhidaeus was Alexander's half-brother, likely intellectually disabled, and was elevated to the throne purely as a puppet by the Macedonian army in the chaos following Alexander's death at Babylon in June 323 BC. These coins were struck in Alexander's name rather than Philip's own — a deliberate political fiction maintaining continuity with the conquests. The Babylon mint was still processing the enormous bullion reserves Alexander had looted from the Persian treasury at Persepolis when this issue was produced.

Philip was murdered on Olympias's orders in 317 BC, ending the regency period these coins represent.
