Strange Coin found in change

Coin FinderCoin Finder Posts: 7,163 ✭✭✭✭✭
This was pulled from change. It was given to me. It grades MS 60 or Au 58. The strange thing about it is the copper ring on both sides of the coin. The copper color is like a rainbow on both sides. This is not a clad error missing error. I did some research and found that this "error" is called a copper wash error. It happens when the planchets a bathed in some sort of solution at the mint. When this solution gets to old it has copper ions in it that start to adhere to the clad metal. Then the coin gets struck.

Can anyone here verify that information? I got it from Anthoney Swieck (sp?)

The scan washes out the copper color but holding this coin in my hand it looks exactly like a rainbow morgan except the "rainbow" is totally copper color.

I suppose this could be easily faked with a battery and a couple of electrodes in a acidic solution, but I know for a fact this was pulled from change from a dealer freind of mine who thinks it is orginal.

    well now that ive read a little more of your post (doggone evelyn wood) I see your researching copper wash. The pics dont show much here, but ive seen different stages of wash...pretty dramatic and some are real cool looking...but not a premium getter. The article i read said something about the wash having bronze or some stuff that when electrically charged causes it to appear devoid of a layer.

    at least thats what I got from the info when I read it.

    hope that helps.

    Actually there are 2 very different ways for a coin to be copperplated.
    Copper washed from where copper particles have dissolved in the cleaning tank and are deposited on the planchet.
    Copper sintered from where copper particles are deposited & baked on the planchets in the tumbling annealing oven.
    Both are common and have little prem.
    Change that we can believe in is that change which is 90% silver.

    I'll have to stand corrected on what I said about them having little prem because I just lost a 3 coin lot by bidding too low. These are nice & heavy copper covered: Text

    I have two coins that look like this, never knew what it was.....How do I tell it's copper wash? Does it weigh more I suppose?
