1999 p dime 1 1

[Stockwiz78]

I have a 1999 p dime with an extra coating , can someone please inform me as to the possible value of this dime.

You have posted in the wrong forum, this is the forum for buying, selling coins.  
I have asked that it be moved to the proper forum.

As far as your coin goes, that is some sort of environmental toning  which is
considered damage and is worth 10 cents.  
Also in  the future, please include photos of both sides of your coin.

It is certainly worth $0.10.

Please show both sides of the coin and the edge, we can only guess that your coin has been damaged from this lone photo, no value over face value.

The "coating" will keep FDR warm in winter....

(It's just discoloration - not a variety, error, or even a turnip. Sorry.)

   The copper-nickel alloy (75% copper, 25% nickel) of which nickels and the outer layers of 1965 to date clad dimes and quarters and of 1971 to date half dollars are composed is chemically reactive and turns a dark red to black color like this when a coin is buried in the earth or otherwise exposed to corrosive substances. The "coating" consists of chemical compounds resulting from the corrosion process. It is of no interest or value to collectors.

“Here Johnny, what do you make of this?”

”Oh, I dunno. A hat? A broach? A pterodactyl?”

“But it’s DIFFERENT. It has to be an important error.”

I know what environmental damage is. I do have a coin that has an extra coating, now can someone give me a estimate on what it could be worth

Already did. Ten cents.

We cannot help you if you do not help us with good photos.   I said earlier that we need photos of both sides and the edge, however, your edge photo is not in focus, well your fingers are but the edge of the coin is not.   Do you have a calibrated scale that can weigh to two decimal places?   If so what is the weight?   Without anything to go on all anyone can say at this point is you have a dime worth ten cents.

Environmental damage, I have found hundreds just like it metal detecting. Dimes are not coated in any way, and there is no place in the minting process where one could somehow get accidentally coated.

[Greenstang]

If you insist it is an extra coating, then it was applied after it left the mint.  
It would be considered damage and as mentioned, worth 10 cents.

How would an extra coating get on the dime at the mint?  That's a question you need to ask yourself when looking for error coins.

It's not possible for a struck coin to then end up with an extra coating at the mint.  If it's not something that could happen at the mint then it's not an error or worth anything extra.

I agree with the others. It looks like some of the dimes Ive found metal detecting. When they are under ground they turn that color. So do quarters. Ive washed several off and put them back in circulation such as probably thousands of other metal detector hobbiest has done. If it really does have another coating then it was probably from a school science project or something like that. It never came from the mint like that. It would be considered post mint damage. A good way to verify it is to weigh it and see if it is in mint tolerance or not.
