This gold coin was bright and clear when I bought it over a year ago. Now I see it has a bunch of spots. I know this diminishes the eye appeal, possibly the value? I assume it can't be corrected, but how to keep from getting worse?

    Here's the other side of that, a little bigger picture:

    Some spots and haze can be removed from gold coins with a quick dip in Jeweluster (sp?). Nice Komodo dragon. I always liked that in both proof and BU. image

    The holder looks to be oversized for the coin (not original holder?). I recommend buying an AirTite holder of the appropriate size to avoid possible rub marks on the coin as it moves around in the bigger holder.

    Mild acids such as lemon juice or citric acid dips are OK, especially on gold...

    You've got some fingerprints there. A quick dip in a commercial solution like Jeweluster, as mentioned (I use EZ-est, which as far as I know is the same thing, pretty much) should do the job.

    The lemon juice idea might be a quicker, easier, and maybe even safer technique. Good suggestion, 7jags. I have recently read of the use of lemon juice to lighten toning on silver coins without totally removing it as a commercial dip would do. Haven't tried it yet, but I will.

    OK, I confess I do occasionally clean coins with the lemon juice, esp. silver. It is pretty slow and will pull some oxidation off the surface. It does not seem to smother lustre the way that Jewel Lustre (sp?) or others do. If the fingerprints are recent do not forget Home Depot sourced acetone which is now about 5.99 per quart.

    DO NOT use cloth wipes, esp if not soft. Having said that I occasionally use them to "tamp" the surface but NOT to wipe or brush across it. I have so many Vickies that well meaning folks wiped and put micro hairlines into what would be otherwise mint state coins that I could cry.

    PS - If you really want to get discouraged about your coins try looking at them through the standard stereo scopes at 30x power!
