[QUOTE="JCro57, post: 4625272, member: 92083"]Roller marks by comparison are lines caused when specks of dirt, grease, or other contaminants adhere to rollers which press planchet strips to a desired thickness. The debris is normally pressed into planchet metal forming incredibly straight, linear, fine parallel lines as the planchet strip is fed through the rollers. Keep in mind that roller marks can appear on any coin - even improper mixtures. The OP's coin does appear to have a minor lamination on Lincoln's face. This could be caused from an improper mixture. However, those lines on the OP's coin are absolutely in line with roller marks, and match them on not one side, but both. This is actually a very easy call im my opinion. Here are more roller marks.
