Æ29 - Caracalla ΝΙΚΑΙΕΩΝ

Nicaea was one of the most prolific municipal mints in Bithynia under the Severan dynasty, issuing bronze coinage continuously through Caracalla's reign — a period during which the city was locked in an ongoing rivalry with Nicomedia over which held the title of first city of the province. That competition played out partly through coinage, with both cities producing increasingly ambitious civic types to advertise their status to the imperial court.

The reference V.2#79877 places this within the Waddell-Voegtlin corpus of Bithynian provincials, a cataloguing tradition still considered the working standard for the series.
