Came across a these while roll searching some Jefferson's. The one on the left has an irregularity on the chin, kind of a wrinkle. The one on the right has a shallow strike area across the braid of his hair. I thought they were interesting...doubtful they'd have any premiums, but my interpretation would be a strike through grease on both?

(Sorry have to settle for scans since I realize I totally suck at picture taking of coins.)
