Hey guys so I am just wondering if there is a way to safely remove the green from the reverse of this coin without scratching it up? I understand that it will still be considered a cleaned coin, but it’s just has a lot of details on both sides that I really think it would be better presented in my collection if the green wasn’t there, however I am fully expecting that the green will probably just have to stay. I found an old album in an old house I was cleaning out and this was in it but unfortunately the album had gotten wet. So this one and a few of the others had green on the reverses.
Order some Verdi-Care from Wizard Supply Co, or from https://verdi.care. It can't make it like new, but it will probably help a lot and won't damage the coin any further.
Other than the value in you finding it, that is a fairly cheap coin to buy in higher grades. I would personally throw that into my jar of old coins and buy a nicer one for an album.
Not much to add to what others have said. Verdi-Care might be able to take off the deposits, although that coin's far enough gone that I'm not sure even it would be completely successful. The reverse will probably look pretty bad even if you do get the verdigris off. And as @JoshuaP said, this particular date/type is pretty cheap and easy to find. You could probably get a problem-free example with less wear than this one for around the cost of a bottle of Verdi-Care.
There is not much you can do for it, but at least it's not a huge loss. The 1883 "No Cents" is common in EF and AU because it was hoarded extensively. People thought it would be rare as a partial year type coin.
