Tetradrachm In the name of Alexander III, Megalopolis

Megalopolis was founded in 371 BC as a Theban strategic project to hem in Sparta, and by the late third century it had become a key node in the Achaean League. These tetradrachms, struck in the name of Alexander III decades after his death, reflect the widespread Macedonian practice of invoking his authority to lend legitimacy to local coinage — a convention so entrenched that posthumous issues in his name were produced across the Greek world well into the second century. Price 748 places this emission firmly within a narrow window that coincides with Macedonian pressure on the Peloponnese under Antigonus III Doson.
