I think they're from the studio Dr. Ilya Prokopov. 1. Julia Titi, 20 mm, 3.5 gr, 300 eur 2. Julia Domna, 3,2 gr, 17 mm, 200 eur 3. Septimius Severus, 3 gr, 17 mm, 100 eur 4. Paulina, 3 gr, 18 mm, 200 eur. Thanks.
The Julia Titi , the Julia Domna and the Septimius are all fake, Couldn't find the Paulina, check out Forum Ancient Coins -- fake reports
The first three are modern struck forgeries. The Julia Titi is way off in terms of style but the Julia Domna and the Septimius Severus dynastic issues are very, very similar in style to genuine examples. They are a little too perfect, however, in terms of centering, strike and circularity of flan. The Paulina has me worried now, because it's a die match to one I bought from a reputable dealer as a genuine Paulina: They are either both genuine or both fake. Mine appears to have circulation wear.
I can echo the thoughts here on the first three: Fake! If the last came from the same source, I would assume fake as well. Guilt by association.
Probably that is why it is always safer to get these coins via reputable auction houses like Kunker/CNG/Stacks/Spink.....or a reputable coin dealer. E-bay takes the cake for outright fakes, esp. ones sources from China/Russia/ Eastern Bloc Countries.
The Paulina is also a die match to this one sold by Lanz at acsearchinfo: Lanz has sold many of these coins from various dies. I suspect it was a hoard find.
The following coins are also from the same vendor, probably all the fakes. Geta 3,1 gr, 17 mm, 40 eur Maximian 4,6 gr, 20 mm, 600 eur Probus 6,2 gr, 21 mm, 800 eur Justin II, 4,5 gr, 20 mm, 300 eur Soaemias 3,1 gr, 17 mm, 60 eur

Another five: Trajan 2,8 gr, 18 mm, 60 eur Septimius 2,7 gr, 17 mm, 60 eur Septimius 2,7 gr, 16 mm, 50 eur Faustina 2,7 gr, 18 mm, 40 eur Crispina 3,2 gr, 18 mm, 50 eur From the same seller.
Last five fakes for avoiding: Hadrijan 3gr, 18 mm, 60 eur Hadrijan 2.8 gr, 18 mm, 60 eur Hadrijan 2,4 gr, 18 mm, 60 eur Trajan 3,2 gr, 16 mm, 60 eur Trajan 3,3 gr, 18 mm, 60 eur
This is offered to me privately from a salesman from Zagreb, Croatia. I do not know if he sells to ebay or any other place.
