help with ancient coin [решено]

Does anyone recognize this? I can't tell what I'm looking at in the second picture. Thanks!

It's a Roman coin from the 350s AD. The image on the right is a Roman soldier spearing a fallen enemy horseman with the Latin Legend FEL TEMP REPARATIO meaning "the happy time(s) restored". The emperor's name is mostly off the flan but almost certainly Constantius II.

Thank you very much!
