[QUOTE="physics-fan3.14, post: 3271668, member: 19165"]Wow. There is a whole lot going on there. I've seen the Ike's with roller lines, as Larry shows. A similar effect can often be seen on Morgans. These roller lines obviously hurt the eye appeal, and will often hurt the grade (a well struck coin should have obliterated the lines). Roller lines usually aren't as prominent as the coin you show, however. They are usually kinda subtle on the Ikes. I'm going to assume that the diagonal parallel lines are the roller lines. That leaves at least two sets of lines left. One of these is the set of semi-circular concave up lines that cover the face of the coin.

The third set of lines are most evident in your first picture, at cross angles to the roller lines. These appear to be clearly cleaning lines. I'd say that this coin has been very harshly cleaned, more than once. It has been polished to death.
