I discussed this coin with Curtis Clay back when I bought the coin. The result of this discussion was that the style is too far removed from the official to be consistent with the output of the IMP II mint. As such I have classified it as unofficial until I can find any evidence to the contrary.
Far be it for me to question
Curtis, but the
reverse looks stylistically right to me. On the
obverse, the nose is more aquiline than most I see on early septimius
Rome work, but not enough that I would have concluded unofficial. But I'm not an authority in the matter, far from it.
I would say I see the greatest stylistic variety of septimius
portraits at the
Rome mint in the 193-194 era.
I would also say that if this is not official, then the piece quoted in
RIC, which unfortunately is not a plate coin, is probably also a copy.
