Came across this one in pocket change lately. Real nice in general for a circulated 1984, but then I noticed the weird marks on the edge of his ear and the doubling on the initials on the reverse! Check it out and tell me what you see!
IMO it looks like plating blisters above the initials. http://www.lincolncentsonline.com/miscellaneous.html Also: http://www.error-ref.com/blisteredplating/
