Have a nice day to all collectors.
I need help, rather refinement from someone who knows this coin and their varieties.

2)Roman provinces - Bithynia and Pontus - Drachm ? NIKAIEΩN; Nicea mint-readable
is similar to this:
Roman provinces (Bithynia and Pontus) -Assarion - Elagabalus -just similar
https://en.numista.com/catalogue/pieces119285.html
weight yeah just dimension is different. Who is it ?
4,51 g, 20 mm, bronze
detail


3) This I can only handle someone knows a more detailed description,
is readable by ,,Valentins,, ,,and Rebublica,, only the mint is ,,SIS,, is at the end of ,,M,, ,, SISM,, What's not?

Thank you if someone helps me.

Third one is Valentinian I if I'm not mistaken, reverse: SECVRITAS-REIPVBLICAE with S in the left field and Q in the right, minted in Siscia (today: Sisak, Croatia). There are a few similar on WildWinds: http://www.wildwinds.com/coins/ric/valentinian_I/t.html but I can't find the one with S Q.

​ Thank you very much,, cro321 ,, - I know it's your cup of coffee.
I'll keep looking, hopefully I will find similar.

Correction:
I did not see the letter ,, S ,, -sorry, I couldn't do it and I did the detail. and it can also be ,, K ,, or ,, R ,,


thanks Ivan

Yes, it's possible it's that one.

As for the second coin it is a provincial issue. The emperor's portrait looks young so it can be Elagabalus. Don't worry if the diameter is a bit off, these are hammered coins so they can vary in size and weight.
