Billon follis of Constantine I

Derek Henderson said he unearthed this small Roman coin whilst he was detecting in Lincoln. He said it measures 17mm in diameter but similar coins are usually closer to 20mm in diameter.

In volume IV of David Sear’s Roman Coins and Their Values this coin is listed as billon follis of Constantine I.  On the obverse, facing left, is a laureate head of the emperor and a legend reading CONSTANTINVS AVG.

On the reverse Constantine is depicted on horseback flanked by S F. The legend on this side reads ADVENTVS AVG N and in the exergue are the mint letters (PLN) for London. The type was struck at London during AD 313-14 and the nearest reference number in Sear is 15863.  

Valuation

The images are not too good so it is difficult to assess the grade of this coin. The reverse is near VF but the obverse isn’t as good. From what I can see of it coin my price range would be £25-35.
