The only problem is that
RIC 399 is
RESTITVT ORBIS, as opposed to yours which is RISTITVTOR
ORBIS.
Would it be possible for you to get a better picture of the
reverse? I suspect that your coin is
RIC 348
Cyzicus:
IMP AVRELIANVS
AVG -
radiate and
cuirassed bust right
RESTITVTOR ORBIS - Emperor facing left holding spear receiving a
wreath from a woman facing right
mintmark of A, B, gamma, delta, or epsilon (any of the single character marks could easily be missed under that small
bit of encrustation or if that portion of the
reverse were weakly struck)
When I zoom in on the pic you provided there does appear to be something (delta?) in
exergue below the woman's foot.
