looks like a small die dent or die chip beside Lincoln's head. you are finding too much with that microscope but keep it up , you are learning . you may even be the one to find the next unattributed error or variety coin . I wish you lots of luck.
That was the last time you are allowed to claim I found something with a scope. How many times do i need to point out that I use my eye balls, sometimes 1.5 foster grant cheater glasses, or a 10 x loupe. The scope is for presenting an image for your viewing pleasure since the scanners were not good enough. capiche?
