This is what Richard Reece states on the Barbarous Radiate in his book "The Coinage Of Roman Britain:
"At present I assume that the Barbarous Radiates continues in use to some extent until the next really common coins flooded the market, in 330."
The official issues of the Fallen Horseman type date from after the death of Constantine I, in 337.
This is what Richard has to say on the Fallen Horseman type:
"The official versions of these coins are not common in Britain, but occur in great numbers in the eastern Mediterranean in particular. In Britain, yet another wave of copying occured, and this time there is never any difficulty in distinguishing between originals and copies. The originals all over the empire are quite large coins, 20 mm diameter and over; the copies rarely reach 15 mm, and go down to 2 or 3 mm. The design goes to pieces, so that identification depends on recognising the hindquarters of the horse or the straight line of the spear. The copies often occur in hoards, such as that found at the Roman temple of Lydney on the west bank of the river Severn."
