Lincoln Lamination Errors Or Not ?

No, not really
more like cracks that are lifting
around dates profiles etc. and one is more like peeling
of the copper plating from edge of rim and in.
Mostly on newer date cents. I'm assuming the error would only be if it was done during the die process. Other cracking, peeling or lifting
of the lam. could be just post damage ? I know this pic. is small
but it shows around date and mm. On this coin also, one crack that starts right at lincolns forehead (hairline)and follows contour of face all the way down to chin. On another (i will get pic.)severe lifting (peeling) of lam. from bottom of obv. rim and up. You can still see lettering on planchet underneath

Metalman is right, you are looking at rot in places where the plating is damaged. The strike itself can actually move the plating around and cause the breaks in the plating. On a less circulated coin, with less rot, you can often see the zinc core inside the breaks of the plating.

At first look I thought this one was a coin that someone pressed into the Obverse and rolled it across the coin.

But looking closer you can see where the copper fell off the shoulder and forehead.
