Here's mine. This is the first slabbed coin I ever purchased. I bought it because it was my birthyear and I thought it looked really cool.

 

Nice!
That one is real dark and coppery.

 

I love it. If you didn't know better, you'd think it was struck on a copper planchet. Really the only nickel color is a little blotch on Jefferson's shoulder and a hint around the motto.

 

Nice. Thanks for the link, very helpful.

 

No one has a black beauty?

I have quite a few coins pulled from new rolls that fit this designation/Definition.
I will photo a few a little later and this weekend.

 

Here is one that is dark in hand, and doesn't follow the look of a mint release.
What do you think?
Found within months of release.

 

Does this near black quarter in BU count as one too?

 

Here is one of mine.

 

Keep em going folks. Black beauty's always work. They are the coins that brought us the error. I have a few somewhere.

 

Here is another. It is more spectacular in hand.
