Looks like ordinary wear with environmental damage on both sides. The right side obverse has a slight MAD but that is very common. It is a WAM, the CAM is the one you hope to find for 1992…imo…Spark Edited to add: To be clear, there are no errors on this coin besides the slight MAD.
What you are probably seeing is Pareidolia. Looks like a number but it is not. A stain or a plating issue
Yes, I looked at the entire coin…it’s 1. damage, 2. environmental damage and 3. circulation wear. The Mint did not put the numbers 7 and 2 on a special die so that you would see them in front of Lincoln’s lips/below his nose, I agree with @paddyman98 …paredolia! The second 9 of the date has “smushed number” syndrome caused by millions of fingers…imo…Spark
