Following the Augustan reform, the production of Roman Imperial coins was at first located in the mint of Rome (1) and supported by various “central” mints spread around the Western part of the Empire: Emerita, Lugdunum and the Eastern part: Ephesus, Pergamum and Antiochia ad Orontem. Their production, although issued firstly for a wide regional circulation, was nevertheless considered universal currency within the Empire (2, 3, and 4).
It is well known that other local mints, the so called “provincial” ones, were located throughout the Roman Empire; they produced coins for their specific l territorial needs, with monetary typologies related to cities and/or regions.
Only recently the numismatic research has identified the presence of auxiliary production centres active for a coinage entirely similar to the one coming from the Rome mint. The majority were along the Rheno-Danubian limes areas. Their emissions were most likely controlled by the Legion military command.
