Philip II, antoninianus, silver, reign as Caesar under Philip I, minted AD

Philip II, antoninianus, silver, reign as Caesar under Philip I, minted AD 244–249, weight 3.8 g, diameter 22 mm. Obverse: legend M IVL PHILIPPVS CAES; radiate, draped and cuirassed youthful bust right. Reverse: legend PRINCIPI IVVENT; Philip II in military dress standing right, holding globe in left hand and transverse spear in right. Strike: mid-third-century Rome issue, centered on moderately broad flans with typical die alignment. Toning: even light grey with localized darker highlights and residual silvering. References: RIC IV Philip I 216C; recorded in major auction catalogues as lot 2.0, ID L5-37. Struck while Philip II held the junior title of Caesar, this coin formed part of a propaganda series that proclaimed his role as heir during a period of military tension along the frontiers. The globe symbolizes universal dominion, and the transverse spear denotes martial readiness, reinforcing the image of the emperor’s son as leader of Rome’s youth (princeps iuventutis). Issued from the principal mint at Rome, the type circulated widely until the fall of both Philip I and Philip II in 249, making it a primary numismatic testament to their brief dynastic program.
