I believe it is what is called lathe lines.

I think gx is right, they look like lathe lines.

 

Lathe lines like the others have said already

 

I have now learned something new I would appreciate input from everyone on my two error clip posts

 

Pretty cool.

 

So then, are lathe lines considered an error or just a poor quality die, er what?

 

What I have gathered from the website, and some forum discussions I found here, and other sites is this. They are "very rare". They are mint errors in that the lathe lines are in the die. They are supposed to be removed before the die is complete. The coins were struck and quality control let them pass, or were unaware of their existence
However there are 15 different obverse varieties for the 1996D Lincoln. They are labeled and categorized just like doubled dies or mint marks.
Fascinating stuff
