I know, DON"T CLEAN, but...


I've read many of the postings admonishing one not to clean coins.

So, do you just leave coins with corrosion in 2x2s?
Don't they get worse or possibly contaminate other coins?
What do the preservation companies do?

    Uhhh, nothing personal but that one is beyond help and is common as dirt as well, even in unc. You gotta "know when to hold 'em" on this and others as well. I think that cleaning has its place but not until the coin is accurately observed and appreciated for what it is (or isn't).

    Q: "Don't they get worse or possibly contaminate other coins? "

    Yes, do not put junk coins in the same album with "problem free". I have a feeling the PVC will see a new home and wreck it faster than SECTION 8ers. ! image

    Welcome.

    The posted coin is a perfect candidate for you to experiment with preservation. Search the threads for PVC, acetone, etc. and give it a go. I'd say you have nothing to lose with this particular coin. Be sure to post your efforts and results (and always include pics in a case like this).

    Welcome, if it were mine I would soak in pure acetone overnight. I did a search on PVC damage on this forum and followed the advice given. Good luck

    Hey - welcome to the forum! Both coins look to be beyond help, as was already stated - the copper especially. They may be nice golf ball markers, but numismatically, any value (beyond sentimental) that they might have carried is gone...

    Also stated was to not keep coins with active corrosion or PVC arond other coins - I agree with that. Why take unnecessary chances? Most of all, though, WELCOME!

    Most people who clean coins don't know how to do it so ruin the coin. Many will clean a coin that doesn't need cleaning lowering the value of that coin. However many coins do need cleaning. Any metal detectorist will tell you that dug coins need to be washed of dirt. I'm not sure how to halt corrosion but that should be done if you are keeping the coin. PVC and scotch tape residue can be removed with Acetone and that should be done.

    WELCOME!

    Keep looking and collecting! Not much to worry about with those two. Certainly foreign
    coins are worth collecting and we don't see them much so they can be hard to find locally.
    Those examples are certainly not expensive coins and you could try just trading them for
    coins without problems. Perhaps if you have a bunch of foreign coins you could sell them
    as a lot on ebay. Just post a good pic of two (showing the problems) and sell them that
    way. Use the money to find better examples that don't have the problems these have.

    Regardless, keep collecting and always be on the lookout for new stuff!

    Those are precisely the coins you can clean without any fear of devaluation.

    Cleaning and conservation are two different things.

    Carefully removing verdigris or corrosion would be conservation.

    Thank you all for the clarification.

    Here is the problem that started me searching this forum.

    image

    A friend has a great number of Indian cents.

    It seems they got wetter than he knew.

    What is the best course to rescue whatever can be rescued from this?

    That is a box on IHCs. Do not touch those with anything more than what is mentioned here. They are what they are. Take out the rolls one at a time and pull the nicest coins out of the tubes to eventually put 2x2's. Look for being able to read all or most of Liberty on anything before 1884 and the have the coin in uniform milk chocolate brown color and free of any PVC or spots. For coins that may have anything that looks like goop on them, give them a quick rinse in Acetone. Use the Acetone in a well ventlated place. Do not rub or touch the coin with anything more then a q-tip, and that should be done very gently with a dabbing motion and not a back and forth motion. Let air dry and then put in the 2x2's.

    Take some picture of some of the ones that you find and post them here.

    This is conservation and not cleaning.

    Also, don't use acetone anywhere near a flame.

    He did mention that "they got wetter than he knew". Copper+water=the potential of all sorts of nasty things to the coins.

    You may want to get them out of the tubes to air dry... Soon. Lay them out on a soft surface and do not rub them. Take a few photos and report back here.

    Thank you all for the welcome and advice.

    I should say I was speculating when I said the coins got wet. A freind is selling them and was surprised when he pulled them out and we saw all the corrosion. I don't really know how it happened.

    He sent them home with me to sort and salvage what I could before we decide on a fair price

    image

    The good news is the coins aren't high end. Most seem to be goods with a lesser number of fines.

    I saw this auction on ebay:

    http://cgi.ebay.com/1909-Indian-Head-Cent_W0QQitemZ260482176172QQcmdZViewItemQQptZCoins_US_Individual?hash=item3ca5f294ac

    Do people actully buy coins in that condition? Is there no way to at least neutralize the corrosion?

    Welcome aboard. If the 'corrosion' is verdigris, acetone should help. If it is something that has 'grown' due to previous contamination, it would have to be examined by experts to determine the remedy.. if one is available. Cheers, RickO

    For litely corroded coins like the one in the auction, a soaking in olive oil will help. I find lots of corroded coins metal detecting image . If I want to spead the process up cleaning a copper coin that I dug, I use hot olive oil on the coin (be careful-needs to be near boiling point) and then a quick plunge in a glass of ice water- this will remove alot of the gunk. Severe spots will have damage left behind from the pitting.

    If the 'corrosion' is verdigris, acetone should help.

    The arrest of growth of the substance we know as verdigris is not going to be helped by treating the coin that has such on it with acetone.Acetone is useful to remove some things that get on coins but verdigris is not one of them.Having said that,there is nothing wrong with treating these IHC's with acetone.Definitely avoid using water.

    There is nothing,as far as I know,that one can do to remove spots or patches of verdigris (salts of copper) on a coin without noticeably and adversely affecting the appearance of the coin.

    Coins that have gotten wet and have begun to corrode like these Indian cents are pretty much goners.

    Of course,better date or key IHC would get more money for the owner but should be left alone.Any attempt to remove the corrosion will most likely make the piece even more undesireable to a collector and will most certainly decrease its value even more.

    Copper coins with active corrosion like the 1962 halfpenny justify drastic action...better a harshly cleaned coin than one that's destroyed.

    I've had success with soaking copper coins in mineral oil. Actually I used olive oil but am told mineral oil is better. Soak the coins for a very long time. You can try to remove dirt and verdigris with a q-tip but be gentle. Corrosion will stop while they are in the oil. It may be enough for some of them.

    Not for this particular problem, but what about canned air or a very soft brush (like sable, camel hair) to remove loose lint or dust?
