Waited a few months, finally got to buy this cool error coin! edit..Slab revealed

I was first shown this coin by my local dealer when it was raw. A customer of his worked at a local bank and discovered it in a bag of Lincoln cents on July 19, 1983, according to the flip in which he gave it to the dealer.
Luckily I was one of the first ones to see it and told the dealer that if it was available I was certainly interested in it. He told me that they had to send it to NGC first before the customer would decide #1-whether he wanted to sell it or not and#2-what price he would want for it. The dealer told me that he would probably know after the Balttimore show.
So this past Sunday I went in and the dealer told me the customer whose coin it was had just left and he had agreed to sell the piece, gotta give credit and thanks to my dealer Harry of D&H Coins for making it happen!
Does anyone know what this error is called? (The only way I know is by what NGC called it on the slab
)

Yes, it is, but I don't think that's the proper name

<< <i>A Split off after strike copper layer, interesting.
That's what I thought it would be called by NGC, but they didn't

<< <i>Well, what is the weight. Got a side picture?
Or they could BB is for damage.
I didn't get to weigh it or take any photos before it was slabbed. It would be kind of hard to take side photos with it in the slab now.
It's so thin you can clearly see the date and the profile backwards and incuse in the reverse photo, as well as a few distorted letters of 'Liberty.'

<< <i>i'd be afraid they'd wunna lock me up for proclaiming that as being something or should i say i'd have to escape again >>
Well, NGC hasn't come to arrest my dealer yet, so I think I'm safe there
Anyone else on the morning crew know what NGC called it? I'll post the slab in a little while

You do find die caps with the bottom partially detached. But you never find zinc cents with a mushy, zinc obverse (the presumptive mate of such a "shell").
<< <i>It's the bottom of a late-stage die cap. I don't know what NGC called it, tho. >>
I'll guess that NGC called it a struck copper layer or a struck fragment.

Did NGC get it right?
It is very thin, and in non-collector terms I would call it a shell of the obverse. What really got me liking this was that I could read the date backwards and I have never seen anything like this before.

Hella cool error though!!
Hell, I don't need to exercise.....I get enough just pushing my luck.
Eited to add: they did, however, get the "obverse" part correct.

<< <i>The Mint would call this a piece of SCRAP METAL so NGC is wrong.
The term "scrap" is nonspecific and uninformative. There are at least a dozen different errors that have had the name "scrap" attached to them.
Congrats on buying it. Certainly is a piece of Numismatic History. I also dig that NGC gave it a 64 grade.
<< <i>partially plated and split after struck? >>
The exposure of the zinc core is due to the numerous strikes this cap bottom was subjected to. The many strikes thin the copper plating until it splits and spreads apart from tensile stress.
