Ancient coin, Probably Roman. Coin identification. [solved]

It is hard to make out but the bust on the Obv. Depicts a bearded right facing man wearing a spiked helmet, with the Rev. Being of a apparent Legionnare holding a spear or staff in one hand. I don't know the characters on either side though. It weights in at about 1.6 grams, I will provide the dimensions later when I can. Any help with identifying this coin would be helpful, thank you.

Definitely later roman

I believe the spiky crown means it was an antoninianus

Yes, antoninianus ("radiate" / “spiked helmet”), I believe it's of Claudius II Gothicus (obv legend from 12 to 3 o'clock [V]DIVS), rev: someone (probably Fortuna) standing, holding rod/spear/sword/staff in right hand and what looks like a cornucopia in left, S in right field,  legend DVX (probably "FORTVNA REDVX")

cf   N#290129

Thank you for the help. It's unfortunate about the PVC poison or corrosio on the coin because the bust is great.

Hello

A bath in acetone can help with the pvc damage 

Thats, a good idea, I might give that a try, and if it looks better Ill post another picture.

don't forget to rinse it well with clean water 

and dry without rubbing with a soft cloth

Will do, thanks again.

It cleared it up a little bit, but the green stuff isn't coming off that well. Oh well, I might try and remove it later, being a little harsher on the coin, just because I got it for free in a bulk lot, but I'll have to see. Thanks for all the help everyone.
