Æ35 - Antoninus Pius ΜΕΙΛΗϹΙΩΝ ΚΩΙΩΝ

The alliance coinage struck jointly between Cos and Miletus — indicated by the ΜΕΙΛΗϹΙΩΝ ΚΩΙΩΝ legend — belongs to a well-documented but still poorly understood phenomenon of homonoia issues produced across the Greek East during the Antonine period. These pieces were not trade coins in any functional sense; they commemorated formal declarations of concord between cities, likely tied to shared cult affiliations or resolved civic disputes. Cos had obvious claims to prestige through its association with Asclepius, while Miletus, though diminished from its archaic prominence, remained a significant regional center in the Conventus of Halicarnassus.

The rarity of surviving specimens in any condition reflects limited original production runs rather than heavy circulation.
