I can't seem to make it out, but there is something wrong with the obverse legend? It should read " IMP C M AVR SEV ALEXAND AVG", but the letter next to to S doesn't look right. Also, with this legend Virtus should be facing right?
Is it the rare Ebola commemorative? My coin below is also missing something and has a common error but it may be unofficial rather than just Eastern.
It seems the engraver made a P instead of an E on the obverse, and also the T is missing from VIRTVS, but there are deeper mysteries in this coin. RIC does not record a Virtus-left reverse for the coins with IMP C M AVR SEV ALEXAND AVG obverse legends. Virtus-left is listed with coins that have obverse legend IMP SEV ALEXAND AVG. And even then, the description of Virtus is, "Holding victory and resting hand on shield, spear against his left arm." However, on this coin, it appears to be the reverse type similar to the emperor standing left with down-turned spear, holding a globe, except it's Victory rather than a globe. (And he's not stepping on a helmet, but wearing one.) A very curious jumble of devices, legends, and errors.
Yes. You got it folks. There are several factors interesting with this one. The VIRVS AVG legend is quite neat and having once been a software engineer appealed on multiple levels. I have seen one other example from the same die on the market. The coin is of eastern manufacture and the reverse type is unlisted for all the reasons identified by JA above. I have also seen one example of this reverse from the eastern mint with the correct VIRTVS legend. The coin copies the reverse from a type from Rome:- Martin
