Æ18

Klazomenai, an Ionian city on a small island connected to the mainland by a causeway Alexander the Great reportedly had built, had a long minting tradition stretching back to the archaic electrum coinage of the sixth century BC. By the Hellenistic period the city operated under shifting Seleucid and later Pergamene influence before passing to Rome after the bequest of Attalos III in 133 BC. The broad date range assigned to this type reflects genuine scholarly uncertainty — the civic bronze series of minor Ionian mints resists tight chronological attribution without hoard evidence.
