Centenionalis of Constantine

This Roman bronze coin is only about 20mm in diameter but is shown greatly enlarged. It was sent in by Mike Ruczynski, who asked for a full ID and a valuation.

The coin is a billon (very base silver) centenionalis of Constantine the Great, who became emperor in AD 307 and after a reign of 30 years he died in AD 337. On the obverse is a laureate bust of Constantine and a legend reading CONSTANTINVS AVG. On the reverse is a depiction of the gate (with a star above) of a military camp and the legend on this side reads PROVIDENTIAE AVGG. Below the gate are the mint letters for London (LON).

In volume IV of David Sear’s Roman Coins and Their Values coins of this type are listed as number 16237. The date of striking was AD 324-25.


Mike’s coin would grade about VF. It’s not a scarce type so my highest price range would be £15 to £18.
