Viminacium was situated near Kostolats, Serbia on the River Danube. It was founded in the first century BC and promoted to a colony in the year 239, during the reign of Gordian III. Viminacium acquired the right to mint its own copper money. The local mint operated from the year 239/240 to 254/255. There were interruptions in the years 248/249 and 253/254, probably due to hindrances in ore supplies to the mint, caused by an unstable military and political situation.
