(In about 324 AD, the Londinium mint was producing two coin types. One was of Constantine with a SARMATIA DEVICTA reverse, and the other was a CAESARVM NOSTRORVM reverse used on coins of Crispus and Constantine II. This coin is a mixture of the two, with a Constantine obverse and a reverse used for Crispus and Constantine II. In other parts of the Empire, coins of Constantine were produced with a CAESARVM NOSTRORVM reverse, but on those occasions they had VOT XX in the middle of the reverse, and not VOT X like this one. The Forum Members' Gallery has similar coins produced at the Ticinium and Heraclea mints.)
