Hi,
common reverse FEL TEMP REPARATIO with soldier spearing a fallen horseman and letter M in left field.
I'd say obverse is of Julian II with a lettering like D N IVLIANVS NOB C and a bare-headed portrait to right.
Struck between 355 and 361.
I can't read out the mintmark but could be either Sirmium or Siscia.
See similar coins

My opinion: value around $10.
