Copper dime? pics inside

[Dark]

Hey everyone.
I found this dime in my register today and I have been unable to find any information about it.
The side of it shows all copper and no other layer.
Is this a post mint modification?
Thanks in advance!

It could be a wrong planchet in the die, but the rim should be a lot thicker. How does the thickness compare to regular dimes? It is heavier. A dime should weigh 2.268

Hmm thats interesting.
The rim doesn't seem thicker than a normal dime and the rim does have ridges like a normal dime.

Maybe it was tumbled in vinegar with copper pennies

It looks stained to me. I would use a soft eraser under water to confirm.

Maybe someone plated a dime with copper for fun. It could explain it being the right size but slightly higher weight.

or to pass off as an error.

MrSchutz has it right, vinegar mixed with copper.

Interesting.
I got it in my penny tray in my register at work. So if someone did go through all that work he lost 9 cents on his investment.

That says it could be worth $400. I am definitely going to look into this. I will keep you folks posted. :-)

Sorry, that's impossible. It would weigh significantly LESS if it was missing the cladding. Your's weighs more.

Aw bummer!

Not worth selling on eBay especially since it weights more instead of less.
