This denarius is one from a group of four Roman silver coins that came in from Mike Ruczynski. I was asked to provide identifications and valuations on them all.
The first coin is a denarius of Diva Faustina Senior, who had been the wife of Antoninus Pius. After her death in AD 141 Faustina was deified and a few years later a large series of coins was issued in her name.
On the obverse of this denarius the legend reads DIVA FAVSTINA around the draped bust of Faustina. On the reverse the standing figure of Providentia has a billowing veil in one hand and a globe in the other.
In volume II of David Sear’s Roman Coins and Their Values denarii of this type are listed as number 4578. They date from some time after AD 147 and were struck at Rome.
Mike’s find would grade good Fine but it isn’t particularly scarce, so my best price range would be £35 – £45.
