I was looking at this 1988-D Lincoln cent and looking for the "FG" mistake, I saw this and I can't tell if it's a 1988 with the 1989 "FG" real or I'm seeing what I'm seeing cuz of zinc deteriation? Anyone?
no, its just a plating blister, your coin has no serif on the crossbar of the "G"... http://doubleddie.com/58348.html
