Claudius II, Billon antoninianus, Milan mint. 268 AD.

IMP CLAVDIVS PF AVG, radiate, draped, cuirassed bust right.
FELIC TENPO, Felicitas standing left, holding caduceus and 
sceptre.
Officina letter T below.

Morgat-en-Crozon hoard 759; RIC V-1, 145 Milan var (rev legend.).

Note: Many people think that TENPO is an engraver's error.
However, in his article about the coinage and mints of 
Claudius II, Märkl gave a convincing argument that the 
spelling was deliberate and was one way of distinguishing
the Milan version of this reverse type.
