Minted at Lugdunum (Lyons), in AD 77 or 78. R.I.C. (Vol. II) (2007 ed.) No. 1223. Apparently quite rare; only a few specimens are known to the authors of R.I.C. Absent from the Biblioteque Nationale catalogue, and decidedly superior to the British Museum's example. The coin also has a very beautiful two-tone green patina.
