There has been a bit of a debate over the date of this coin with its unusual, for the period, reverse type. C.H.V. Sutherland, the author of volume VI of RIC, suggests it was struck in 310 or 311 to celebrate Constantine’s victories over the Alemanni and the Franks. Pierre Bastien connected it to no specific donative, while Georges Depeyrot assigns it to 312-313, presumably in honor of Constantine’s victory over Maxentius at the Battle of the Milvian Bridge. Constantine was now the sole ruler of the West, and had purportedly cordial relations with Licinius I, who would emerge victorious in his struggle with Maximinus I and rule the East.
