Æ16 - Antoninus Pius ΝΕΙΚΟ

Nicomedia served as the effective administrative capital of Bithynia under Roman rule, and its civic bronze coinage under Antoninus Pius reflects a city actively broadcasting its status during one of the empire's most stable and prosperous reigns. The abbreviated ethnic ΝΕΙΚΟ identifies the issuing city without ambiguity in the regional context.

At this module and weight, the piece falls among the smaller denominations circulating locally — functional small change rather than prestige issue.
