Sestertius - Gordian III Viminacium

Viminacium, the legionary fortress-city on the Danube in Moesia Superior, was granted colonial status under Gordian III and immediately began issuing its own dated bronze coinage — an unusual privilege reflecting the city's strategic importance as a frontier command center against Gothic and Carpi incursions. The local era begins in 239 AD, making these pieces precisely datable within the series by their AN (year) numerals, a rarity among provincial bronzes of this period.

The AMNG references span multiple die varieties catalogued by Pick, with meaningful obverse and reverse die distinctions across the numbered sequence.
