    What ever one does in restoration, it should be annotated and reversible.

    This coin was taped to a piece of manilla paper. What do you suggest I do about it to get rid of adhesive? Should I soak it in just water, alcohol, or acetone to get rid of any residue left?

    Personally, I would suggest acetone and a cotton swab if necessary.

    I didn't see any tape left or adhesive but I don't want it to damage it if there is any left. Will it damage the coin if it is left on the coin? I kind of don't know if I want to mess with it.

    BadThad is the member to ask, especially regarding copper coins. PM him, I am sure he would be happy to reply.

    Adhesive needs special solvents. Aside from being very reactive, it is usually hydrophobic, and possibly gummy. Delicate use of a wooden cotton swab with organic solvent, and a nice clamped coin, using a magnifying glass, is the way to go.

    If there was tape on the coin, then it is a given that there is residue on the coin.

    Yes.

    That's up to you. What you are faced with is what do you consider to be the lesser of two evils. 1 - the tape residue will in time change the coin. 2 - removing the tape residue by soaking the coin in acetone will remove the tape residue. But acetone sometimes causes copper coins to turn weird colors over time. It does not always happen, but it does happen.

    Your choice which way to go.

    Of course the better choice is to not have bought the coin to begin with.

    Very interesting question and situation. This is not an MS coin, and has survived 170+ years of life in the real world. I take Doug's advice that acetone can disturb copper seriously. If you want to use acetone on this coin, go ahead, it is an excellent solvent to remove organic residues like any adhesive left on the surface. However I would follow that up with a bath in water followed by a rinse with distilled water to counteract anything bad the acetone may have done. Lets face it, I don't think this coin would be harmed by washing it with a mild soap or detergent as long as it is thoroughly rinsed with water and then with distilled water. Just my opinion. BTW, nice coin, I really like large cents.

    I actually contacted BadThad about this and he said something about soaking it in distilled water to start. The seller didn't know much about coins and I contacted him about doing this, taping coins to something. I actually got this for $11 along with a low grade common v nickel, I just used acetone on that. It was listed as an "1887 Liberty Cent" in the V Nickel section along with the v nickel. I wouldn't return it because I could get more for it if I resell it myself and re-list it properly.. I am thinking I may just list and note that it had been taped to something and I would suggest soaking it in distilled water to remove any tape residue. Of course there was no way to know the seller would have done this. How about alcohol and distilled water will that help? That is what I usually use on wheat cents and have used this on another large cent that was previously cleaned. That coin is turning brown again. When I got it, it was orange. I emailed the seller and I was right, they didn't know not to do this. Of course if they knew what they were doing, they wouldn't have listed it as an 1834 Matron Head / Coronet Large Cent and not a "1884 Liberty Cent" in the V Nickel Section with a coin worth a buck.

    I did find this article on removing adhesive and alcohol is listed. I think I would try that since I know alcohol and distilled water are acceptable to use on copper and won't change the coins color something I think would be unacceptable. By the way, the green stuff on the v nickel I spoke of before just peeled right off after soaking it and rubbing it lightly with a q-tip. There is still a sticky strip on the coin that is coming off. I should have took a before picture.

    Yes, distilled water is the first step. I usually skip the first step and head straight for the acetone, then a rinse of distilled water.

    I am thinking alcohol and distilled water since alcohol removes adhesive but doesn't harm copper like acetone. I am reading in to many places that acetone can react with copper.

    My understanding is acetone is fine for copper. BadThad suggests it and he is a chemist. However, I think there are parties on both sides of the acetone issue. I am sure alcohol will be just fine because it should dissolve the adhesive and you should be able to use a cotton swab with the alcohol.

    Yeah and gold doesn't tone either, but it does ;)

    Very funny. I guess i'll have to wait a few years to see if some of my acetoned cents are truly affected.

    I think I will toss a copper memorial into acetone to see what it does but as far as this large cent is concerned, I wouldn't risk it.
