Triassarion - Commodus ΗΓ ΚΑΙΚ ΜΑΤΕΡΝοΥ ΜΑΡΚΙΑΝΟΠΟΛΕΙΤΩΝ

Marcianopolis, founded by Trajan and named for his sister Marciana, became one of the more prolific bronze-issuing civic mints in Moesia Inferior during the Antonine and Severan periods. The magistrate name preserved in the obverse legend — Maternus — helps anchor this piece within the sequence of local governors whose tenures structured the city's coinage, though the precise chronology of individual magistracies in this province remains only partially resolved by scholarship.

The ΗΓ control mark denotes the third of a series of denominations struck at Marcianopolis, with the triassarion being a three-assaria bronze common to the Danubian civic mints.
