This penny was just in too good of shape that got my attention. It's bent or Twisted but has a Wavy appearance on back. Word of worn or Stamped different. Am I missing something or looking too hard?
Poor pictures, but the closest I can tell is that the surface is just that way due to a worn die strike
UNITED STATES OF AMERICA was struck through grease.. That's why the letters are faint. Common. Nothing major.
