This is the first of two Roman coins that came in from Robin Dones, who asked me to provide full IDs and valuations.
Coin number one is a denarius of Antoninus Pius, whose dates are AD 138 to 161. On the obverse the legend reads ANTONINVS AVG PIVS P P IMP II around the laureate head of the emperor. On the reverse the seated figure of Salus is feeding from a patera a serpent coiled around and rising up from an altar; the surrounding legend reads TR POT XX COS IIII.
In volume II of David Sear’s Roman Coins and Their Values denarii like this one are listed as number 4126. The type was struck at Rome in AD 155-56.
The obverse has been struck off centre but the coin is otherwise in about VF condition. However, the flan is a dead grey in colour and this might put off some collectors who prefer denarii to be more silvery. As it stands, my price range would be £40 -£50.
