Ancient Roman....HELP!

Not very good with the old Romans....anybody help me with this one?
Thanks

Poor image, so I can not pinpoint to an exact attribution.  You will need to verify and pinpoint the attribution yourself (see http://www.wildwinds.com/coins/ric/probus/i.html and http://probvs.net/probvs/) so the following attribution is similar to your coin:

Roman Empire: Marcus Aurelius Probus (276-282 CE) AE Antoninianus (RIC-36)

Obv: IMP C M AVR PROBVS P F AVG; Radiate, cuirassed bust right
Rev: MARS VICTOR; Mars walking right, holding spear and trophy

The following coin is NOT mine and hence has been posted for illustrative purposes:

Thanks Quant.Geek,
Looks like you have pointed me in the right direction....have not found an exact match yet but several are very similar!
