The coin featured here is number three from a batch of seven Roman denarii sent in by Robin Dones. This specimen was struck when the Civil War had ended and Vespasian has become Emperor of the vast Roman Empire.
On the obverse is a very impressive laureate head of Vespasian and a legend that reads IMP CAESAR VESPASIANVS AVG. On the reverse the seated figure of Pax holds an olive branch and a caduceus and the legend on this side reads COS ITER TR POT. In volume I of David Sear’s Roman Coins and Their Values this denarius is listed as number 2285. The type was struck at Rome during AD 70.
The obverse is almost VF, the reverse about VF with some staining. In its present condition I would give it a price range of £80 – £100.
