For most of his reign he was the colleague and rival of Constantine I, with whom he co-authored the Edict of Milan that granted official toleration to Christians in the Roman Empire.
In 324, he was finally defeated by Constantine after almost a decade of on-and-off civil war. He was spared at first, but then hanged a year later.

BTR is a bit strange and I belive it is an engraving error as only PTR exists for this which follows perfect logic as in the west officina were "numbered" via the first letter in the Latin words for first, second (prima, secunda) etc., and in the east they did the same but with the Greek words (alpha, beta) etc.
There is also substantial die wear causing the first four letters of the obverse inscription to be almost entirely missing when striking the coin.
