MIneral OIL?

I have heard advice that the olny way to remove gunk and dirt
without destroying value would be to soak the coins(pennys) in pure mineral oil. Do you guys consider this to be doctoring or altering? I have a few coins soaking right now so i can confirm a few veriatys i think are on the coins. Of corse I would disclose to any buyer what has ben done to them. I am just wondering if there are any qualms about doing this?

    The oil just loosens the grime and caked on dirt. I wouldn't call it doctoring. People buy ancient coins that have been dug that have crusted on dirt. Olive oil is one thing they soak them in.

    Drink a bottle of it and it will clean out your dirt and gunk.

    If it's good enough fo your colon, it's good enough for coins.

    I have a bottle of mineral oil on my shelf - right next to the acetone, the denatured alcohol, the baking soda, the eZest, the MS70, the isopropyl alcohol, the olive oil, etc.

    Have you tried using them all at the same time?

    Truth is, I'm not really sure. It happened by accident. I was experimenting trying to figure out a way to remove milk spots - the obverse is covered with them. So, I pretty much tried everything on the shelf over a period of a couple weeks. Of course, nothing worked. I tucked the coin away in the cabinet reverse down, and forgot about it. About a year later I found it and that's what it looked like.

    No that's not doctoring because you not altering the surface of the coin. BUTT you might expose a bad surface readily identifying it as a problem coin. I got a dugup Buffalo Nickel soaking in some Marvel Mystery Oil right now. MMO is good stuff with great gunk removing capabilities but I never tried it on coins before. You might want to experiment with that too.

    Mineral oil is the best!

    Better than olive oil as it does not turn rancid.

    But do not use it on proof coins for obvious reasons.
