Antigonos I Monophthalmos, a principal Diadoch of Alexander III, controlled much of Asia Minor and the Levant until his defeat at Ipsos in 301 BC. His mints, including Tarsos, continued issuing silver in Alexander’s name to secure monetary continuity and broad acceptability across former imperial markets. These posthumous Alexander types financed Antigonos’s campaigns and administration and illustrate the political strategy of invoking Alexander’s authority while new Hellenistic monarchies emerged.
