I am 90% sure that it is an antoninianus of
Trebonius Gallus.
To my eye, the first part of the obverse legend appears to be
'IMP.C.C.VIB (TREB' above the radiate crown).(etc)
The letters do not appear to be 'VOLVS', which would have indicated that it is a coin of his son Volusian.
Perhaps not too surprising that the portraits of the father and son look similar.
The die cutters may not have had a plaster bust issued to them, from which to model the son's image onto the coin. die.
