Will the Sniffer reject my copper...

that has been kept raw since the late eighties, because I protected the surfaces with Blue Ribbon? Do you guys think that acetone to the surfaces are necessary before submitting (in order to avoid rejection of my coins)? Thanks for your opinions. Don, could you chime in on this image, please?!?

    The coins in question are all Palestine Mandate and not US. I wanted to ask the question generically and not be accused of using the wrong forum by posting pics of foreign, on the Lightside. I also figured that I would get a better array of responses here, due to the larger base of posters. I'd be glad to post a few if I'm given the 'green light'.

    Will acetone work on Blue Ribbon (whatever that is)? I thought acetone will only remove organics.

    Hmmmm, snif, snif, snif....

    I believe Blue Ribbon, at least the newer stuff, is glorified mineral spirits. The older stuff I think had higher levels of CFC's in them, but all versions are basically 'organic' and should be quite soluble in acetone.
    I would think that if the Blue Ribbon were applied in the late '80's, there wouldn't be much of it left on the surfaces by now. And I have had large cents certified by both major services that had been treated with Blue Ribbon, but I was careful to ensure there was no greasy appearance from excess residue.

    I thought Acetone and Copper did not work well and gave it a pink color?

    I recall banned member FEC showing before and after acetone IHC pics and the results where a bit horrific to my eyes.

    Jeweluster, which is an acid dip, will turn copper pink. I don't recall using acetone on copper myself, but don't think there would be a serious problem with it. It think it will give the coins a 'dried out' look.
    If there is a concern, take a common pre-'82 Lincoln cent and give it an acetone soak - let us know how it turns out.

    I think I've seen posts that had evidence that acetone may have changed the color of red copper.

    However, i would not use acetone on large cents. I like a "natural" amount of oil on them, enough to fill the pores and protect the coin but not enough to leave a sheen. Most older slabbed large cents have a bit of oil on the, sometimes more than you would want.

    The "coin sniffer" is somewhat like a drug test. When they test you for drugs do the look for all known drugs? No, they have to test for each drug or family of drugs. The "coin sniffer" would look for what they tell it to look for. They can't look for oils or it could be rejected for normal skin oil. Besides, oil is not one of the deceptive items they are looking for. I'm sure interpretation of positives will be a key to the effectiveness of the "sniffer". --Jerry

    I would imagine the coin with untreated residue will fail - well it will. Mild detergent (ie dishcleaning) with much irrigation of water to the surface will work. Horror of horrors I actually use my fingers to apply it and work it with the water, a lot and that strips the surface of residue (with NO fingerprints) and no reactions to surface. BTW, even CFCs are organics, as are mineral spirits...

    Correct - that's what I said:

    You want to use Xylol (well vemtilated) on copper - I have seen it do wonders to clean it up. Use a rose thorn to "pick" at it.
  • joecopperjoecopper Posts: 1,195 ✭✭✭
    PS - chuck the sniffer, copper should not be slabbed
  • 7Jaguars7Jaguars Posts: 7,736 ✭✭✭✭✭
    Xylol = deadly poison. Watch that one, I would avoid...

    Ooops, sorry walkerguy, my bad on your beating me to it.
