Tetrachalkon - Seleukeia Pieria

Seleukeia Pieria occupied a peculiar political position in the late second and early first centuries BC — nominally under Seleucid authority but increasingly autonomous as the dynasty collapsed under dynastic civil war and Tigranes of Armenia's encroaching power. By 83 BC the city would fall entirely under Tigranes, but in the narrow window of 90–89 BC it was still issuing civic bronze under its own name, a sign of the administrative vacuum the warring Seleucid pretenders had left behind.
