Dated Antoninianus of Postumus AD 259 (COS I)
Radiate, cuirassed bust right.
IMP C POSTVMVS PF AVG
Rev: Emperor stg left holding globe (?) & spear
(P)M TR(P C)OS I PI - final sector of legend blundered.
This coin conforms to RIC Vol V Pt II 53 (Lugdunum).
The style of the bust has greater stylistic affinities to
the Aes coinage rather than the Antoninianii of Postumus
- and that this is an early portrait of Postumus is given credence by the
dating (COS I) to the very start of the reign.
