Antigonos I, one of Alexander the Great’s senior generals, controlled much of Asia Minor after 323 BC and continued the prolific coinage in Alexander’s name to maintain the familiar Attic-standard currency and project dynastic legitimacy. Kolophon was an active Ionian mint for these posthumous issues, and the standard Herakles/Zeus types became the primary silver currency of the Diadochi during the wars that culminated in Antigonos’ defeat at Ipsos in 301 BC.
