Æ34 - Antoninus Pius ΚΩΙΩΝ ΜΕΙΛΗϹΙΩΝ

Cos maintained a special relationship with Rome throughout the imperial period, rooted partly in the island's famous medical tradition — the Asclepion at Cos was among the most celebrated healing sanctuaries in the ancient world, and Augustus himself had granted the island tax exemption in recognition of its physician Xenophon, who had served Claudius. The joint legend pairing Cos with Miletus is unusual and reflects a moment of civic alliance or shared honorific initiative rather than administrative merger — both cities operated independently within the Conventus of Halicarnassus.

The IV.2 reference places this within the exhaustive BMC/RPC framework for Asian civic bronzes under Antoninus Pius, a reign notable for its almost total absence of military crisis — which paradoxically flooded provincial mints with the resources to strike prestige civic issues.
