Greetings. I have a 1983 P unc details Lincoln Memorial cent
with odd features that do not match acknowledged varieties and errors guides I know.
The obverse is straightforward but the obverse is irregular.
The reverse issues are in the upper left and lower left quadrants.
1) Upper left memorial is very worn - almost to field;
2) D - ST are worn the same at their lowest points;
3) E of E Pluribus is weak, worn, and mostly invisible;
4) Striations to the northwest throughout the area and adjacent areas. They are almost perfectly parallel. L-U-R-I-B are relatively flatter than the rest of the word. UNUM is strong and even. In PLURIBUS, the right side of R and all of I are quite flat. Left part of B is also flat. Lines on the left portion of the area contain deeper ruts and rectangles and unlike die polishing lines you see in Morgan VAMs, e.g. Distance between lines seem greater than what I have seen in VAM
errors, but those were silver coins.
5) There appears to be an "S" in the field between the upper left memorial and the D-S. It is quite apparent with modest magnification and raised, especially on its right side. The image does not change when I rotate the coin.
6) There is the possibility of a "9" nearby, but it is too faint to be sure. Ironically, the "E" of E-Pluribus disappears with coin rotation since it is so faint.
1) Something between O and N in ONE. It appears raised and highly visible to the eye. I am not sure whether it truly a clash. Nearby marks probably exist but are not so clear.
2) Another "S" like image appears between the N and E in ONE.
I get that emerging tarnish impacts visibility and can fool the eye. So, before I order a Maclaren, what do you think? Is the coin worth investigating further with a grading service or is it just another dirty, worn coin?
Thanks for you help.
