** 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.
