Constantine I “the Great” (AD 306–337). Roman Empire.
Æ Follis (c. AD 306–310), struck at [likely Trier, London, or other western mint depending on mark].
Obverse: IMP C FL CONSTANTINVS P F AVG — Laureate, draped, and cuirassed bust of Constantine I facing right.
Reverse: IOVI CONSERVATORI — Jupiter standing left, holding Victory on globe and scepter; eagle at feet holding wreath. Mintmark in exergue.
Specifications:
Denomination: AE Follis
Diameter: ~26–28 mm (varies)
Weight: ~8–10 g (varies by issue)
References: RIC VI (depending on mint and officina); NGC certified
Historical Note:
The IOVI CONSERVATORI reverse (“Jupiter the Protector”) emphasizes Jupiter’s role as guardian of the emperor and the empire. Constantine’s early coinage, issued while he was still aligned with the Tetrarchic system, prominently honored Jupiter as a divine protector. This theme later shifted toward Christian iconography as Constantine consolidated power and distanced himself from the old pagan system.
This type is a classic representation of Constantine’s transitional period — still rooted in the imagery of the Tetrarchy, yet foreshadowing his eventual role as Rome’s first Christian emperor. Coins of this series often circulated widely and mark a significant turning point in Roman numismatic and religious history.
