MS 64 is my call as well. However, I am not sure your coin will holder at a third party grading company. Those apparent scratches behind Liberty's head give me pause. Super Dave is correct about the possibility of PVC contamination.

the scratches behind the head don't appear to be in the metal but surface smudge. is there anything I can do for the PVC contamination?

WOW>>>.. ok I took a cotton sock to this coin. no water or solution. just a slight rub. the tarnish or contamination came off really easy you can still see the marks behind the head. but they are not deep scratches   |

Wow that makes a big difference, as I said earlier MS-64. Value increased $65-$70.

Personally, I would rather have the coin as it is with a light rub then what it had before, so I don't think the monetary impact was too bad. That said, it is rarely a good idea to clean coins.

A Q-tip will kill a silver coin, if used dry. Furthermore, if the green on the coin is PVC, this treatment did not solve the problem. |

Rubbing is never a good thing to do. I have looked over these pictures very closely and have been able to enlarge the image to over 200% and I not seeing any hair lines. Though as SuperDave said if they are present than the coin would be ungradeable and the value reduced.

Ugh, that coin has a very unnatural look now  Quote:
I am afraid to use anything on the surface You were afraid to use water or acetone but not afraid to rub the coin  Water and organic solvents such as acetone will only remove surface contaminants, they will not harm the metal They will not even remove the toning because that is part of the metal. ANY type of mechanical friction on a coin will leave scratches, regardless of how soft an item you may think you are using. As SuperDave mentioned, even a cotton q-tip will leave marks. Reminds me of this thread from a few months ago. Edited by biokemist6

I appreciate all of feedback. I knew there was a chance to screw up the coin . The tarnish was so bad and much different then the back. I thought I would see how it came out. I

Bio I think the unatural look has more to do with lighting. There is still a nice petina on the coin. Again thanks for all the feedback. I am learning a ton

What I am referring to is the hazy appearance around the devices in constrast to bright reflective fields- that is a classic sign of cleaning.

to be honest, I think it looked better before and I am a big fan of white coins but the after shots look nowhere as good as the before ones do. You should never ever use anything like cloth or a cotton swab even because they will both leave microscopic scratches in the silver coin which ruins the coins surface. I would have tried 100% acetone on it at the most and never wiped it with anything. On a brighter note, your pictures are better

Take the coin out on a bright day, and look at it under a loupe in direct sunlight. If you can rotate and tilt the coin without seeing hairlines, you've dodged the bullet. Sunlight is merciless for revealing such things, as is halogen lighting under the camera, but both will only work at the right angle to the hairlines if they're there.
Wish you'd asked, if you wanted the color to go away. We could have hooked you up with far less-invasive methods. On the bright side, in the grand scheme of things this was not a particularly important coin; they're common in high grades.
