This is the first from a group of Roman coins that came in from Mike Ruczynski on behalf of himself and his brother, John.
The coin is a denarius of Antoninus Pius, whose dates are AD 138-161. On the obverse is a right-facing laureate head of the emperor and if the whole of the legend was visible then it would read ANTONINVS AVG PIVS P P IMP II. On the reverse the standing figure of Annona holds corn ears over a modius in one hand and rests the other hand on a rudder set on a prow . The full legend on the reverse would read TR POT XX COS IIII.
In volume II of David Sear’s Roman Coins and Their Values denarii of this type is listed as number 4131; they were struck at Rome during AD 157-58.
The obverse would grade good Fine but has been struck off centre. The reverse would grade Fine. This type isn’t scarce so in its present condition I’d price this denarius at £25
