East roman empire [решено]

I think I can reader some letters but didnt find it.

Maybe valerianus and gloria on the reverse. 

It's Valentinian I

RIC IX is a bit weird in that it gives multiple numbers to indistinguishable coins.  The correct way to interpret this is that this mintmark was used both before and after the elevation of Gratian, so it could be any time between 364 and 375.

Thank you!
