The dark circle around Lincoln's head in the second photo is the reflection of the camera's lens, demonstrating the highly reflective surfaces of the coin.
As a collector of both coins and variety of small antique items, I have been buying and selling on eBay for more than a quarter-century...Really, check my perfect feedback, which makes me one of eBay's longest, continuously active sellers/buyers.
I am also selling here on eBay my entire PCGS registry set of Lincolns, currently ranked 14th. The 383 coins include all of the key dates in uncirculated condition, such as the1909-S VDB, 1909-S, 1910-S, 1922-D, 1931-S and D mints,1955 doubled die and the 1990 no-S proof. The 1914-D and 1922 no D cents are XFs, and the entire list can be viewed at PCGS.com look for Murphey's Best PCGS Abes under the Lincoln cents, circulation and proof, with major varieties 1909-Present. This coin is not included in the set.
If you have a question, please do not hesitate to ask, because as a long-retired newspaper editor who trained dozens of reporters, I well know that the only dumb question is the one NOT asked.
