one_fine_dime Pillar of the Community United States 591 Posts	Posted 03/29/2021 8:34 pm Thanks so much for all the great feedback here. I guess I should have mentioned that I do not (as yet) own this coin. This question was in part to help me decide if it (might) be worthwhile to make a go at purchasing this coin, but only if the price was "right". Next time I'll clarify whether or not I own it, as I see many here assumed it was my coin. I guess my thinking was that many potential buyers could be turned off to a coin like this and therefore it could go for under book value. Clearly it is a high(er) grade coin, with much remaining luster and other quality attributes. This is a semi-key date in the series and a date I've been certainly keeping my eye out for. These deposits do appear to be raised, rather than incused into the coin surface, and I do see where it looks like they have come off and more or less left the patina stained - thank you for those observations. In my mind it would be a risky purchase at book value, but say picking this up at XF40 pricing could be worth the risk. I have my eye on a few other potentials that don't have issues like this one, so we'll see. I agree an acetone dip is a very easy first attempt, other subsequent approaches like toothpick picking or ultrasonic cleaning seem more risky to me....but so many folks are saying toothpicks are fine, I could try that if I end up with this coin. Has anyone used the PCGS restoration service at all? I am curious how they would approach a coin like this. Report this Post to the Staff

Always good to do a final flowing rinse with fresh acetone.

jafo50 Valued Member United States 175 Posts	Posted 03/30/2021 12:46 pm If you can purchase this coin at 'the right price' you might want to consider conservation services offered by some TPG companies. They would evaluate the coin to determine if it would benefit by conserving it or not. Just something to think about. Report this Post to the Staff
macmercury Pillar of the Community United States 5832 Posts	Posted 04/03/2021 10:00 pm After looking at it again, this maybe just dry up black ink, a soak in water for an hour or two should clear it up, if that's just black ink. Report this Post to the Staff
whatdowehavehere Valued Member Canada 235 Posts	Posted 04/29/2021 1:08 pm You can do this: 25% CLR and water. Try it for 10 minutes or so; any surface junk should be removed. Keep immersing to remove all of it. Rinse and pat with a paper towel, The black maaaaay turn gunmetal blue. It it doesn't, there is an easy to ameliorate it Report this Post to the Staff
