Lugdunum quinarius Bastien 588 (coll. G.
Gautier, 1,42g, 6h, same pair of dies).
It belongs to the 12 emission, which P.

reverse die with the equivalent
quinarius for
Maximian (MAXIMIANVS

bust, B. 589, 1 ex., British Museum, 1,91g, 12h), which in turn shares its
obverse die with quinarii bearing the
reverse VICTORI/A

shield V X (
Votis Decennalibus) which allows to date these series.
