I found this 1992P in a $50 bag (first time I've purchased more than a couple single rolls from the bank). I've gone through several 1992's so far, but this one caught my eye. On the reverse, there seems to be an extra something that runs diagonally from the leg on the left side of the Memorial. It's probably nothing special, but I've not seen it on any of the other 1992's I've seen so far, and I don't see anything listed on CC, VV or Wexler's. Any thoughts would be appreciated. Thanks for looking.
