Here is another coin (in fact obverse die) from the eastern mints of Septimius Severus to which there isn't an entirely satisfactory answer. I will start with my newest coin. Obv:– IMP CAE L SEP SEV PERT AVG COS - (II), Laureate head right Rev:- BONI EVINTVS(sic), Fides standing left holding basket of fruit and corn ears Minted in Emesa, 194 - 195 A.D. Reference:- RIC -, BMCRE - (EVINTVS instead of EVENTVS) No there are two strokes under the bust that I read as the II but they are very weak scratches rather than convincing letters. A legend ending COS makes no sense in this series but then again we have other coins ending COS I, CO II, II C etc. Are those scratched really there on the doe or are they an artefact of the strike? I have seen a few coins from the same obverse die and even own a few. The marks are there on these examples too but are equally weak. I don't have any answers for the reading of this die but keep my eyes open for it. My newest coin has an odd reverse legend too that I have seen on a Pescennius Niger coin (calling @dougsmit)..... and so the two elements combined with a low enough price made this new coin interesting enough to buy.
I would have bought the coin for either of its sides. Maybe you are losing interest in Septimius and ready to turn your thousands of coins loose on the market so I have a chance at finding them???? This was my first Pescennius Niger coin and I have not seen a duplicate of it but I am not the guy dealers contact when they want to sell a PN. I bought it in 1997 from the late Guy Clark.
