Hi!

I believe I can read "(...)[A]VT KAI ANTON(...)" which should be greek inscriptions for something like
Autokrator Caesar Antoninus. So my vote would go either to Caracalla or Elagabalus.
Sadly I am not able to understand the letters before (...)ΠOΛITΩ[N] on the reverse, which could point out the city of origin.
If you carried it for such a long time I will assume it did brought you luck
