1996-D Lincoln Memorial Cent (Cud?)

What does the outside edge look like. Does it look like a struck through debris on the edge? (I'm torn three ways on this one) It looks like metal striation lines on the last image. Note how the metal is showing glare in that image? That metal striation lines reminds me on metal movement during the strike, or a round edge on the die that has broken recently.
1. So of there is metal on the outside edge of the coin, then it might be a struck though debris. (Weight should be slightly over 2.5 grams)
2. Is there any any other evidence of Machine Doubling on the coin. That could create the striation lines on that edge on the rim look.
3. Is there evidence of weakness of strike on the reverse opposite that area? If so then it might be a Cud. So a bit more needs to be known about this coin.

Looking at all three images, it looks like something peeled of the edge leaving a slightly lowered area on the edge.

Looks like it was struck with debris, that may have covered part of the reverse edge also, but left a flat spot on the edge and two edges showing where it tore off the edge during circulation. That is what I'm seeing on this coin.
