Assuming the vertical lines are raised, as they appear to be in the photo, it looks to my non-expert eyes like die scratches, perhaps from the eject mechanism.
I thought this also but have never seen vertical damage, just horizontal, but I'm also in the unknown as to if the feeder finger process might have changed over the years.
Feeder finger gouges. On Lincoln Wheat Cents the are usual vertically aligned on the obverse. http://www.error-ref.com/accidental-die-abrasion/.
