The reverse shows it is 1992 or earlier.
I don't see any lathe lines on the blank side and would recommend you post a photo of this coin on a scale and see if it weighs either 3.1 or 2.5 grams (zinc), if the weight is correct, it could be a genuine error (2 planchets entering the die chamber), if underweight it is
PMD.
If the weight is correct (and genuine), maybe Mike Diamond can comment on why the reverse side does not exhibit a stronger (pressure) strike if a second planchet was involved.
Another guess would be struck with a late stage capped die as I can now see a very faint outline of Lincoln, but that may be a optical illusion on my part.
