Got this Lincoln in change today, care to guess the grade? It's not often you see one in this condition.......
That doesn't look like circulation wear to me. Looks like rapid abrasion -- like someone stuck it on a sander or something. If normal wear, AG-3. If not, I'd need to see the back, but would probably call it F-12 detail, abrasion damage.
Yea has to be sanded, under a microscope there are not any real obvious striations, but a fine enough grit probably wouldn't show strongly. The reverse is just as nice as the obverse. LOL It measures about 4 mm thick, a normal wear 1979 is about 6 mm. This is a good one for the PGGS (Penny Guy Grading Service) with a high enough fee this could go XF45.
I vote for a good luck charm on the poker table. It could be worth millions at the final table of the world series of poker.
