    No i still don't know who Clark Smith is.

    I can tell you for a fact though that any coin dealer that tells you to use nail polish remover on a coin is as reputable as an antique dealer who advises you to use sandpaper to remove a speck of grease from a piece of Claris Cliffe.


    Just don't do it.

    GoldCoinLover,

    From your latest picture of the coin, the mark that you refer to, appears to be a gouge! If so, then no amount of rubbing or cleaning will remove it from the coin.

    I would suggest that you invest in a quality Gem Loupe or several Gem Loupes of varying powers of magnification. With these, you will be able to identify any damage, corrosion, doubling and any other odd looking items on coins.


    Good luck...Frank

    Better still don't buy coins that you're not happy with. If it's got a scratch and it bothers you then let it pass by, other coins will come along. Obviously i understand this is not practisable with coins bought sight unseen.

    If you get something sight unseen though you should check that the dealer has return policy (before you buy the coin) and secondly if you don't like it don't try improving it in any way, send it back and get a refund.

    I agree, it is weird. Mixed messages on coin cleaning are abundant, in my opinion. Cleaning a coin is clearly a bad idea, but cleaning solutions and methods are everywhere.

    If you don't like the coin, just return it and get over it.

    OK - let's start at the beginning here. The black mark is the result of toning. Most folks think gold doesn't tone much, it does a little, but not much. However, the alloys found in gold coins do tone. And if it is a case of a bad alloy mix, they can tone a lot. Those black marks are not uncommon on gold coins from this time period.

    Now to the next part - trying to rub a spot like that off a coin with your thumb - will hurt the coin. You should never even touch the surface of a coin with your fingers - the fingerprints alone will hurt the coin. That's why they tell you to always hold a coin only by the edges . Trying to scrape it off with your fingernail will hurt the coin and it will most definitely scratch it.

    Now there are those who say that that the utrasonic cleaners will not hurt a coin - they may be right. Personally I do not know as I have never tried one. But I would be hesitant to do so.

    The reason the black mark does not show up in the pics is because it is toning. In many cases, to capture toning in a pic you have to take the pic at the right angle. If you do not - the toning will not be visible in the pic. Anyone who has ever tired to photograph a toned coin knows this.

    Let me also add something here...I never have tried an utrasonic cleaning but from what I have read about it and people that have used it...its not good...I think there was something about it in CoinWorld this year...

    There may be some benefit to experimenting with ultrasonic cleaning, starting with some inexpensive coins to examine the results. I can't offhand think of how this might damage the coin in any way that could be detected even under magnification except through water spots, which may be avoidable depending on the solution. On the other hand, I also don't think it would remove toning [a chemical reaction], but might be good for a substance on the surface of the coin.

    I'm not convinced that there isn't a way to safely clean a coin. We all know what doesn't work, but that doesn't mean nothing works. Edison experimented with thousands of substances before he found a suitable filament for the light bulb.

    James Taylor said it the best...any coin that has had anything (talking about cleaning) that happened outside the mint is not meant for the coin and is therefor not good...and lowers the value.

    No reason to ask a question if you don't pay attention to the advice.

    There are people with 20 years of experience and people with 1 year of experience 20 times. I have known both and the first is better

    Thanks. I agree I fingerprints can ruin the coin. And I agree to hold it by the edges.
    However it doesnt look like toning to me. I've had copper spots before, and this looks totally different. It almost looks like a gouge, like someone mentioned, that was filled

    And you can't scratch gold with your fingernail. There are only certain elements you can scratch with your fingernail, you can only scratch gold with a knife.

    It's possible - but I doubt it.

    Sorry to tell you this - but you are dead wrong. Gold is one of the softest metals there is - and the most easily scratched.

    Gold is soft, but gold alloyed with other metals cannot be scratched with a fingernail. Pure gold, maybe. The other alloys in the metal strengthen the gold and make it more durable. Gold is scratched easily, but it cannot be scratched by a fingernail. If you don't believe me, I will get out my book of elements and look it up for you.

    Thanks for the ....... whatever this was?

    Have a nice evening.

    P.S. Try using some of your gold coins as emery boards. I am sure they will look great when you are done.

    If you have 11 years experience then you should already know that nail polish remover is bad and that coins should not be scratched by finger nail or by knife. There are more germs up fingernails than anywhere.

    If you were not aware of this then i don't know how you missed it. I've been collecting 15 years and i learned most of those basic points in my first year.
