Æ16 - Trajan ΚΩΙΩΝ

Cos sat administratively within the Conventus of Halicarnassus, one of the judicial districts Rome imposed on Asia Minor to manage provincial litigation and local governance. The island's mint was modest by any measure, producing small bronzes for purely local exchange — pieces that rarely traveled far and consequently turn up in findspot concentrations close to the Aegean coast.

III#2163 is not a common type within the Trajanic civic issues of the conventus.
