Nephew just put fingerprints on lustrous SLQ

He just did it yesterday. Thank goodness he didn't scratch it or walk away with it. I'm assuming that to prevent fingerprints from showing later all I need to do is give it a short soak in pure acetone, correct?

    Try acetone first, then wait and see. If something does show up later, if it were my coin, I would try ammonia briefly followed by water rinse and then acetone. Hope the coin and the nephew are OK!

    If the fingerprint ever shows up, it will be pedigreed to your nephew....

    How old was your nephew? Was the coin in a holder of some kind or was it just laying around raw? In any event, the acetone should take the print off but I wouldn't wait too long to do it.

    ms-70 will work. I haven't had any luck with acetone for fingerprints

    soak a Q-tip and lightly ROLL it across the surface. Rinse with water and dip in acetone last

    For fingerprints, on a lustrous surface, I have found the application of Dawn liquid dishwashing soap, directly on the surface (very soon after the print is applied) will remove the oils/acids before etching takes place. Follow that with a hot water rinse and acetone soak. Cheers, RickO

    I recommend banning him from your house until he's 15 or so...that will ensure this never happens again.

    Try spectral (100%) ethanol. 99% IPA will also do and is available in most drug stores.
    Soft Q tips do a great job for gently working the spot, followed by a soak and rinse.
    Make sure your nephew is watching so he gets a good idea of the trouble caused.
    I would use pure distilled water for any washings. You don't want to deal with the
    salts (minerals) and chlorine in ordinary tap water. Good Luck!

    acetone should do the trick.

    Wow. It's amazing to see all of the theories and recommendations, with almost no agreement between them. Better living through chemistry. I would be interested to hear back from you after you have applied one of the recommended treatments, to learn what success you might have.

    I really don't think it will be all that serious as very recent fingerprints will come off with no residual with these techniques. The soap alone will remove it most likely but the residual must definately be removed with liberal rinse with warm/hot water and tamped dry with a soft cotton nap towel.

    I use acetone a lot too but the above will be fine if you don't have it. Alcohol also works, even isopropyl with the same after rinse. These treatments are not all that different since they are using solvents to remove the oil based residue that does not yet even have the acid element that comes with bacterial action on the oil yet...

    He's 4, just came into town for the weekend. I had it in a flip in a desk drawer. I think I'll use isopropyl alcohol.

    I've used Dawn on filthy coins that I didn't want to abraisively clean with good results. Dawn is great at cutting through the grease and oils of finger prints and won't hurt the toning.

    Since he has tiny fingers, just press your own finger over where he did his....that way it will be YOUR fingerprint and not his image

    use acetone and soak for a wee bit...NO MS-70!!!

    that fingerprint is fresh acetone will do it, MS-70 will make that SLQ look MS....whatever grade it is, now...and ruin it unless that is not a concern of yours

    You're in luck. I just read a thread about auctioning a child on ebay.

    ummm, who knows if someone previously handled the coin? if a print shows up you may never know who it belongs to image

    If it's a fresh fingerprint, acetone may do it before the oils can react with the coin and leave a permanent mark. Let's hope for the best.

    That coin will never be the same, sorry.

    the Q tip thingy ain't gonna work without leaving tell-tale signs that say I was rubbed on with a Q-tip.

    Give your nephew a big hug and another coin to play with.

    acetone is proven to be safe on all metals used to strike coins, and it doesn't require a "soak" for what you're describing, simply a rinsing done either by swirling the coin in a shallow bowl or pouring the acetone over the coin. as for the other things mentioned, i don't think there's any proof that the coin will be stable if some residue remains afterward. also, i would never, never, never suggest using a Q-Tip or anything else on a Mint State or Proof coin.

    This method makes sense to me...

    your not going to rub you are going to ROLL the Q-tip..Lightly ROLL the Q-tip..I would challenge someone to show
    damage from very lightly ROLLING a soaked Q-tip over a surface..It will never rub the surface..I have done this on a Proof
    ASE and even under a loop you can't tell.

    Just my thought from experience
  • 7Jaguars7Jaguars Posts: 7,802 ✭✭✭✭✭
    Agreed as I do not see hairlines even with a bit more pressure than "rolling" them on, even with 10x magnification. Maybe 24k gold might but I haven't and likely would not have to on these...
