2000-P Jefferson Nickel Sintered Copper Wash?

It is definatly copper in some areas but there is a dark stain on the left side of the obverse and reverse.

It weighs 5.0 grams.

Just stained. By the way, the terms "sintered plating" and "copper wash" are no longer applicable to genuine examples because there is no sintering (fusion of copper dust) going on and the surface enrichment of copper has nothing to do with the rinse bath. It's all due to overheating the blanks.

I found the info on a few different searches that this is actually an "improperly annealed planchet" http://www.coinworld.com/Articles/V...operly-annea The only thing in this article that applies to my coin is the 3rd picture of an improperly annealed nickel.

Why do you believe my coin is not one of these improperly annealed planchets?

I am going to have a professional grader look at it this weekend and I will report back with what he says it is.

Buddy,
I've read all the stuff that people do to coins but this does not look like them. There is still some luster although it is a circulated coin. The copper on the rim looks like a solid copper core with a plating on it, but from what I read the alloys separate when the blanks are being made do to atmosphere causing solid copper in one area and other alloys in different areas. Sometimes the copper is thick enough it starts to peel off like int the photos in this link. http://www.error-ref.com/improper-annealing.html

The article by Mike Diamond in Coin World describes many different types of coins which some are not confirmed as anything. I would be more than happy to let anyone examine mine. The coin only cost me 5 cents and it don't look like these are worth much more than $20 in circulated condition anyway. This coin is different than most I have seen online but they are all unique. They are usually almost all copper looking or have very little copper this one is in the middle. I am also starting to wonder if the black color is not actually part of the coin and not a stain because sometimes the annealing process leaves them entirely black or partially black.

Some of these coins I have linked to are not graded but I believe them to be true errors.

I showed it to a pro coin grader online and he said it was most likely damage. He also said Mike knows more than he does about these.

I only have one last question. If it were damaged wouldn't it lose weight?

Edit* I guess that quesiton might not make sense since nothing is missing or has fallen off.

The dark spots are copper looking when tilted in different light. Does the copper sometimes turn darker color?

Thanks John, I will try and contact that person and see if they want to view this coin in person. Kris

I found one of my own today. I don't think that my photos are very good. But the color on the rim is pretty accurate.

Also, on the obverse, Jefferson is wearing a really tiny earring.
