We were moving out some things from my grandmothers house, and come across 2 books. Both the same with places for 1959 through 1982. Both are nearly full with some great looking coins, but looking over the secong book i spotted the top pic here. Abes looking a little rough these days, the bottom is the other for comparison. Hopefully somebody can give me some insight
The lines in the field of the first coin says that the die had gone through a die polishing, To remove something. But, if you look at the details of Lincoln, in his face and jaw line, the first got a much stronger strike.
