Verdi-Care might help this coin, it sure wouldn't hurt it. I dip or soak most of the coins I get in an acetone bath just to remove any surface contaminates that may be on the surface, such as finger oils and PVC residue. Most of the coins I get are 2¢ pieces. Don't think that this one will ever look better, but the verdi-care may reduce some of the gunk surrounding the corrosion and possibly preserve what is left of the coin.
