Could anyone help ID this coin? The only thing I know about it is that it needs an olive oil bath for about a month! Hope the images aren't too dark.

It appears to be a silver washed bronze antoninianus of Gallienus, ca 260s. I can't quite make out the reverse legend, but the type is the emperor at left saluting Jupitur (Iovi) who is holding a staff.

Thanks for the replies. Any idea of value on it? I've been told that olive oil will take care of the green........ any thoughts on that would be much appreciated as well.

Value is about $15.00 - $25.00 retail.
