** Obverse:** IMP C C VIB TREB GALLVS P F AVG, Radiate, draped and cuirassed bust right two pellets below
Reverse: SAECVLLVM NOVVM, Roma seated facing on throne within hexastyle temple, holding sceptre
This coin was struck in AD 251-252 in Antioch, and is classified as Sear 9648.
I like this coin because it is basically a reissue of a coin struck only 4 years previously by Philip I Arabs celebrating the 1000th birthday of Rome. Saecullum Novum mean the new milennium. It must have been a real crowd pleaser, as the reverse was also used by Herennius Etruscus, Hostilian, and Volusian.
Portraits from Antioch are always interesting, they definitely use a different style than their Roman counterparts. This particular portrait is not so elegant, I think, but the reverse is clean enough to make up for it imho.
