Centenionalis of Constantine the Great
Colin Barton asked for my help with this Roman coin as he had difficulty pinning it down.
This coin is only 17mm in diameter but is shown greatly enlarged. It’s a billon reduced centenionalis of Constantine the Great. On the obverse the laureate and draped bust of the emperor is accompanied by a legend reading CONSTANTINVS MAX AVG. On the reverse are two soldiers, each holding a spear and a shield resting on the ground. Between the soldiers are two standards and below, in the exergue, are the mint letters (PLG) for Lugdunum.    Â
Valuation
In volume IV of David Sear’s Roman Coins and Their Values this type of centenionalis is listed as number 16337 and is dated to AD 330. Similar coins turn up regularly as detecting finds but Colin’s example is in well above average condition. However, as it is a fairly common type I’d price it no higher than £10.
