Late Roman (probably 5th century) indeed, but the portrait looks too late to be Arcadius, and S PF AVG is not characteristic of any specific emperor. I think I see V before it so it's probably not Leo, Zeno, or Johannes?
If I had to guess, without reference to the reverse, it would be Theodosius II, [D]N THEO[DO]-S[I]VS PF AVG, with the letters in brackets being the ones I can't see the slightest trace of.
Obverse aside, I can't make any sense of the reverse. At this size it could probably be a monogram, but even then, I can't tell whose. I'm tempted to suggest an imitation.
