It will still have value to someone that needs to fill a hole in their folder.......
I agree wholeheartedly! Bathe the coin in Acetone to arrest (stop) the green Verdigris, rinse with water, pat dry with a towel, place the coin in a 2x2 coin holder, then sell it or keep it. The coin has VG details at the least and someone would likely be willing to pay $30 to $40 to fill a hole in their' Collection.
