Found a match on Mad Die Clashes! ADC-1c-1985-01 In bays 7 & 8 are unusual clash marks. Overlays suggest that it is part of Lincoln’s bears and throat. The degree of rotation is about 8 degrees and the misalignment about 5%. This is not enough to constitute a MAD clash entry, but enough to substantiate its inclusion in the Atypical files. The obverse was void of any clash marks.
There you go! Glad you found a match. Now you know why it drops off to a lower area. It’s a mild but tire mint error.
