Approximately 2,315 coins (plus a possible 51 addenda). This comprises 484 'radiate' coins from the period A.D. 260-96; 288 nummi of the first, second and third tetrarchies (Diocletian, Maximian, colleagues and successors, 294/5 - 307); 184 reduced-weight nummi, c.307-10; and 1,359 nummi spanning further reductions in weight after 310, the large majority in the name of Constantine I ('the Great', 306-37). The latest coins were struck at London and Arles, c.318. The hoard was buried in a jar of local South Wales grey ware, probably late third - early fourth century A.D.


The hoard was found on the same site as another hoard of Roman coins (Wales 08.4; NMGW-085CE6).

Both related hoards comprise Roman coins produced in the quarter-century following Diocletian's reform of the Roman imperial coinage around A.D. 294-5. The coins are of copper alloys that contain small proportions of added silver, originally with silver-washed surfaces. As found, almost all coins are encrusted with copper corrosion products, mainly malachite.
