Maybe I’m being too hopeful here but I think this is a variety of a Domitian 88 AD secular games issue Sestertius. See the portrait shape and the MTR at 1 o’clock. The reverse is wiped. Do you think I’m right, is it something else or is too far gone to tell? Other 88 AD sestertius Secular Games Issue Sestertius:
I think it could be Vespasian but the Titus portraits on the sestertius looks too different in my opinion.
Most certainly Vespasian; can't figure out what is on the reverse, maybe PRINCEPS IVVENTVT with Spes standing: http://numismatics.org/ocre/id/ric.2_1(2).ves.654
The seller had it as Domitian 81-96 so that was where I was looking but as I’ve looked at Vespasian's I think you’re right.
