Æ20 - Julia Domna GENIO COLON ANTIOCH

Antioch of Pisidia was a Roman military colony — Colonia Caesarea Antiocheia — founded by Augustus around 25 BC to pacify the region and control the Via Sebaste. The GENIO COLON reverse type invokes the protective spirit of that colonial foundation specifically, not the city in any civic sense, which places this issue firmly within the propaganda of Septimius Severus's consolidation of Antonine dynastic legitimacy through Julia Domna's elevation. The ACB unlisted status suggests die combinations or obverse legends that haven't been fully reconciled against surviving specimens.
