The portrait looks like Victorinus, perhaps a contemporary imitation, possibly Pax reverse. Search CNG's archives for Victorinus and you'll see what I mean.
At the size and with the lack of useful legend on the obverse, it could theoretically be a contemporary copy of almost anyone, but Tetricus I is by far the most likely prototype, and without any evidence that it's anyone else, you should probably go with that ID. As for the reverse, I'm almost certain that's Pax. She's holding an olive-branch (off-flan) and scepter - and once again, Pax was the overwhelming choice for reverse device by the numerous contemporary copiers of the era. I guess it was a combination of the intent of the personification - peace in a turbulent time - the simplicity of the figure, and the fact that it took the engraving of only 6 letters to finish the reverse die.
This is a more-or-less typical example of a contemporary copy of a Tetricus Pax Avg antoninianus with largely legible and literate legends, for comparison's sake:
