The reverse type of this imitation, with this particular legend arrangement, is not seen until certain rare issues of the Civil War in AD 68 (AM 92-3), and later on denarii of Galba (RIC I 167). This unusual combination suggests that the coin may in fact be a semi-official issue produced at one of the ephemeral mints of the Civil War period.
