Silique of Valentinian I
Here’s another coin found by Paul Marland. It’s a 4th century Roman silver coin and the denomination is a silique. It was struck for Valentinian I, whose dates are AD 364 to 374.
On the obverse is a diademed, draped and cuirassed bust of the emperor and a legend reading D N VALENTINIANVS P F AVG. On the reverse the standing figure of Valentinian holds a labarum in one hand and the tiny figure of Victory in the other. To the left of the emperor is OF and to the right II. The legend reads RESTITVTOR REI P and in the exergue are the mint letters (CONST) for Constantina.
In AD 326 Arelate (Arles in France) was renamed Constantina in honour of Constantine II; after his death it reverted to Arelate but in AD 353 Constantius II changed it back to Constantina.
Valuation
In volume V of David Sear’s Roman Coins and Their Values  Paul’s find is listed as number 19367 and is said to have been struck between AD 364 and 367. The type is quite attractive but isn’t scarce. The coin would grade good Fine but it has a couple of small edge chips, so I would price it no higher than £40.
