I kindly ask for your help.

 

Can you recognize any letters on the coins?

Unfortunately not my friend

All of them have a big SC surrounded by wreath at the reverse, which reminds me of the Antioch provincials.

You´re completely right, it´s Antioch on the Orontes. As said before weights and diameters can help a lot identifing the correct ruler/ coin type.
