Tetrachalkon

The Magnetes were a loose confederacy of communities along the eastern Thessalian coast, and their autonomous bronze coinage was confined to a relatively narrow window in the late Hellenistic period before Roman administrative reorganization of Macedonia and Thessaly progressively eroded civic minting authority across the region. By 100 BC, most Thessalian leagues were already producing diminished issues or had ceased independent coinage entirely. That the Magnetes continued striking at this date makes their bronzes a minor but genuine marker of lingering federal autonomy.
