Will Acetone Help?

    Thanks! I've never had occasion to clean a coin and kept hearing about acetone. Wasn't sure what it would clean and not clean.

    Acetone's an organic solvent, and will only remove organic deposits from a coin. It's chemically incapable of affecting silver reaction-based toning; simply can't do it. The problem, sometimes, is determining which is which, complicated by the fact that there's crud which could accrue onto a coin which isn't organic.

    As if that weren't enough, one then has to decide whether the successfully-treated coin would be an improvement, or not; irregular patches of removed coverage will then become irregular patches of cleaned-looking areas. For instance, if we propose that the stripes on your Buff are something which acetone could remove completely, the result would be a coin where those areas had become brighter than the surrounding nickel, which has acquired some patina that the acetone wouldn't touch.

    Still striped, just less realistically now. :)

    It's a fairly short list. PVC residue, tape residue, fresh (and only fresh ones) fingerpints, fingernail polish, and some types of paint. That's really about it.

    Now yes, there could be other things on a coin that a rinse in acetone might wash them off, but then so would a rinse in distilled water. My point here being that a rinse in any liquid would wash them off. Not that you should use just any liquid.

    What people need to learn and understand is that different types of solvents work better on different types of things. There's basically 4 liquids that are safe to use on coins, assuming they are used properly. They are:
    1 - distilled water
    2 - acetone
    3 - xylene
    4 - con dip

    And each one of them removes different things from coins better than the other 3.

    Other than those, you shouldn't even try to use it.

    As people know from past posts, I'm an advocate for acetone to remove PVC residue, tape, and other residue. as it is inactive (no acid or base in it) with metal, but in this case I think the nickel has character and should be left alone.

    @britannia40 Thank you for recognizing my :angelic: contribution to CT. It makes it all worthwhile. :muted:

    In response to this advice to collectors of U.S. coins and my comment about many ancient collectors: NEVER scrub your coins with wire brushes. Leave that :jawdrop::facepalm: to the ancient collectors. :hilarious::hilarious::hilarious:

    :oops: It looks like I struck a nerve with this coin scrubber. :jawdrop: BTW, do you consider @SuperDave to be a self-elected, know-it-all of coins? What about Doug? Anyone else here on this thread besides me that makes you feel uncomfortable or inadequate? ;)

    Well you know "he" aka "insider" has slipped a notch since Ed Woods has been on posting here on CT!
    So now he's the #2 most disrespected poster here on CT.
    You know when you're #2 you got to try harder ,or :cow: even more to get the recognition of chief resident troll. :troll:

    I'm with everyone else on this, leave it alone. It is a very nice looking '16 with the "Woody" look. Nothing wrong with it at all.

    Now as for a 'woody', Been a long time since I got one......................purchased one, bought one, found one to buy. Is that stretching the limits of the post ?

    Does the improper alloy mix prevent it from straight grading?

    Insider said....I'm not on CT much any more...... well we truly haven't missed you :yawn:
    I've surrendered to Ed, and now playing with the "Big Boys" Just know that's ok...many here will be glad to hear that you have come out of the closet!
    "Not that there's anything wrong with that!"

    "I've set all time ever records" "racking up over 1.7 K dislikes"

    :rolleyes::facepalm: I did not write goodbye for ever. What I actually wrote: "I'm not on CT much anymore." I love CT and everyone here - especially those members I follow. :kiss::kiss:

    Given time, you may be. There was a time that 'blast white' was the only thing tolerable in my collection, and I would freak out at a coin beginning to 'turn' in an album, flip, or 2x2. Oxidation is an eventuality and I have leaned to accept it........such is old age, as I have lately been oxidizing much, rather of late. :)

    You don't know oxidation until you reach my age. I hate to think how much @GDJMSP has oxidized. He should be mostly old powder by now! ;)
