The Roman silver coin featured here was unearthed by Edward Burns, who had already identified it. However, Edward asked if I could give him some idea of its possible value.
The coin is a denarius of Diva Faustina Senior and dates from some time after AD 147. On the obverse the legend reads DIVA FAVSTINA around the draped bust of the empress. On the reverse is the standing figure of Ceres, who holds a long torch in one hand and corn ears in the other; the legend on this side reads CERES. Ceres was the Roman goddess of agriculture and frequently appears on Roman coins of the 1st and 2nd centuries.
This coin was issued under Antoninus Pius in honour of his deified wife, who died in AD 141. She was the mother of Faustina Junior, who became the wife of Marcus Aurelius. In volume II of David Sear’s Roman Coins and Their Values denarii of this type are listed as number 4591.
On the reverse the legend is weak but the coin is otherwise in about VF condition so my price range would be £50 to £60.
