Historical context

Maximian served as Roman emperor alongside his co-emperor and superior, Diocletian. After serving as Caesar from 285 to 286, Maximian was Augustus from 286 until their joint abdication in 305. Diocletian's political intellect complemented Maximian's military focus, with Maximian campaigning extensively across the empire, including joint operations with Diocletian such as an expedition into Alamannic territory in 288.

This silver antoninianus was produced at the mint of Siscia under Maximian's authority. Introduced originally by Caracalla in 215, the antoninianus was a coin thought to have been valued at two denarii, visually distinguished by a radiate crown. By the late third century, vast quantities of antoniniani circulated across the Roman Empire before being phased out by monetary reforms. The obverse depicts Diocletian with the legend "IMP C C VAL DIOCLETIANVS P F AVG", while the reverse shows Diocletian and the deity Jupiter sacrificing at an altar beneath the inscription "CONSERVATOR AVGG".
