Very hard to say!
It seems like it has been overstruck multiple times, maybe with different dies.
It seems like there's "TIAE CAESS" on it, and (less sure, but matching) "PROVIDE", which would be PROVIDENTIAE CAESS - either campgate or Nicomedia Jupiter type, but then it also has that star-over-crescent mintmark which can only be Arles where PROVIDENTIAE CAESS wouldn't fit.
