 Minting – and control over precious metals in general – across the western empire was under the control of the "Comes sacrarum largitionum", with a number of major mints situated at Trier, Arles, Milan, Ravenna and Rome.London had operated as a mint in the first half of the 4th century, and again for a brief period under Magnus Maximus, but by 400 inflows of coinage to Britain came from the continent.Finds of coins are very numerous from throughout the 4th century and even from the first years of the fifth.
