This penny is a proof, slabbed in an NGC holder. It has a beautiful red sheen and a highly reflective surface that captures the light, softens it, and then bounces it back like a sun on the horizon. It’s a penny, so maybe I’m getting a bit carried away there.
The obverse shows President Abraham Lincoln in profile to the right. The legend “In god we trust” is written in raised letters from 10:00 to 2:00. The motto “Liberty” is to the left of Lincoln, in line with the back of his neck and his beard. The date is to the right of Lincoln’s bowtie and the mint mark (when present) is under the date.
The reverse shows the Lincoln Memorial under the country of origin “United States of America” written from 6:00 to 3:00 The legend “E Pluribus Unum” is written above the monument but below the inscription (that is Latin for “Out of many, one”). The denomination “One Cent” is written from 8:00 to 4:00.
