Should I acetone dip my 1/10 oz and 1 oz American Gold Eagles before putting them in Air Tite containers? :smile:

    no, they will not milkspot like ASE's. There's always the possibility of copper spotting with gold coins but rarely seen on modern gold because of higher purity. And I'm not sure an acetone dip will prevent them. Additionally copper spotting does not affect the gold content of these coins, they remain as pure as the mint indicates. Copper spotting only indicates a high concentration of the very small amount of copper in the coins.

    Agree but it doesn't hurt either. It'll at least get any oily finger prints off.

    I acetone gold before grading to remove any oil hopefully preventing any future problems,,,,,, it doesn't hurt.

    An ounce of prevention is worth a pound of cure.

    I only would if they have fingerprints or PVC on them, otherwise it's really not necessary.

    @1630Boston .... acetone will not react with metals...it is an organic solvent. It will remove organic residues. Not sure what issue you are addressing, but gold is impervious to most solvents - stay away from aqua regia and cyanide.... Other chemicals can affect gold with the application of electric current. Cheers, RickO

    @ricko
    I just want to remove or neutralize any fingerprints, etc before LONG term storage.
    Thanks :smile:

    PS
    I do try to stay away from the MacArthur-Forrest process, it is nasty if not performed under properly controlled conditions. :smile:

    I've read that you can rinse with acetone which will completely evaporate.

    I soak my coins in acetone for 30 minutes or so. Then I pull them out and lay them on a soft bath towel and then I fold it over on them and pat dry. I then immediately hit them with HOT air from a hair dryer turning over several times until they are good and dry.

    I avoid water as a last step due to water spotting. When dipping silver after the dip I rinse under water,,,,,, then soak in a baking soda water mix to neutralize the dip,,,,,, then rinse again with water,,,,,, then soak in acetone,,,,,,,, then the hair dryer route.

    I rinse coins with distilled water after an acetone treatment, and pat dry. Seems to work.

    If the acetone is pure, then it will evaporate from the coin within seconds after removal. At that point, the hair dryer is just a warm placebo. ;)
