Antoninianus - Diocletianus VIRTVTI AVGG, Hercules

The VIRTVTI AVGG type associates Diocletian explicitly with Hercules — a deliberate political pairing that reflected the tetrarchic theology taking shape in the late 280s, where Diocletian aligned himself with Jupiter and his co-emperor Maximian with Hercules. Issuing a coin invoking Herculean virtue under his own name was a calculated assertion of shared divine authority rather than a subordinate one.

RIC V.2 103A places this among the Lugdunum or eastern mint issues of the pre-tetrarchic consolidation period, before the 293 AD reorganization fully standardized output across the empire's mints.
