2009 D Professional Life Lincoln Cent Error Unknown

I found this 2009 D Professional Life Lincoln Cent-Bicentennial Collection in change today.

Right off the bat I noticed the dark color, (almost black), next, the larger than average diameter and lastly, the double rim. It weighs 2.5 grams.

Any ideas on what this error is and is it rare?

looks plated. wait for more opinions...

 

It is damaged. I know it can be done by heating the coin, may be other ways to do it as well.

 

Actually.. It's the opposite. Unplated. Copper plating removed.

 

And then squished between leather (There are other ways of course).


Thanks,

Ok, so how does it weigh 2.5 then? Unless it was 3.11 originally and the copper removed weighed .61. Seems a little odd.

2009 D cents are made of copper plated zinc and weigh 2.5 grams (+/- .13 grams) and the copper plating weighs about .05 grams. So even removing the copper plating the chances of it weighing 2.5 grams is pretty good, especially if your scale is only accurate to one decimal place.
