2000 D 100% Copper Nickel

I have a 2000 D Jefferson Nickel that is 100 % Copper through & through.

Is this a rare occurance? Should it be verified and graded ?

Hi coins4me

Can you post pics ?
I will tell you that to get a coin with no clad layer is not impossible ,but to get one that is an error rather than an altered coin is rare.

I have a few coins that I found metal detecting ,that the clad layer was removed in the cleaning process, in fact a few of them are nickels.

Im not saying this what happened to your coin ,just that it is a possibility that the layer was chemically removed.

Hi ! Rick, Thanks for you response.

Well I am not a chemist so I can't be sure that it is copper, but it certainly looks like copper and looking at the edges it is through the whole coin.

I am not sure how to take a picture of it and what it will show. I do have a scanner if that will work.

This is the best I can do with a scanner. I have included a normal Nickel for comparison. The edge of the coin is of the same coloration.

The nickels that I cleaned certianly turned copper colored !!! I wouldnt have said they did if they didnt!!

Im not sure what the chemical reation was , or the reason for it to be ,I just know it was .

Hey ! You guys are great and fast on the responses. Thanks so much for your imput.
I looked up toning on Google and what I can gather this is just a nice unusal coin to keep. Thanks much for your replies.

may be a "sintered planchet" copper layer deposit.

 

I have a nickel which has the same color, exactly, but only on one side and only partially I'm fairly certain it's toned.

 

It's an example of "sintered plating" or "copper wash". An unintended, thin layer of copper was deposited on the planchet prior to the strike. The origin of the copper is controversial and poorly understood. Folks trace it either to the annealing drum (sintered plating) or the chemical rinse bath (copper wash). Neither explanation accomodates the full range of variation seen in these coins. In any case, accidental copper plating goes back at least to the late 1950's and continues up to the present day. Some of these coins have merely a copper hue, while others have thick plating that's cracking and peeling. These simply represent the ends of an unbroken continuum.

 

Got the old brain...ok not so old but it feels it on a monday morning....working. The term I was looking for was "copper wash", not sintered planchet. This happens during the processing of a planchet. Mike Diamond has posted excellent descriptions of this error before. Copper washing can affect just parts of the coin or the whole thing. I'm not ruling out toning, but looks like a copper washed planchet to me.

 

I have seen a few nickels that were very close to or directly in a fire that turned a copper color! Being that they are composed (I believe) of .750 copper and .250 nickel, the extreme heat probably causes a change that allows the copper to come to the surface. Heat a nickel with a propane torch and you will see what I mean!

Maybe so, but the heat-treated and chemically-treated nickels I've seen do not closely resemble a genuine copper wash / sintered plating error.

 

Mike,

I see what you mean! None of the nickels that I have seen that were close to or in a fire, were mostly dull and most were a light copper in color. I have seen only a few copper-washed or sintered planchet coins and still have a lot to learn about them!


Frank

 

A roasted nickel will not have any mint luster. A genuine uncirculated copper wash / sintered plating error will have full luster.

 

I recently found a 1963 D nickel that looks very similar to what Dave found. I was wondering what these would be worth if they are indeed copper washed, if there is a premium at all. Thanks.
