I'm interested in the opinions folks have on all 4 pictures of this coin. I'm particularly interested in what is going on with LIBERTY. Note the upper inside doubling of the R in liberty is incomplete.
Flat and shelflike does not make it a Doubled Die variety. That's just common worthless doubling. All issues on your Cent are just caused by die deterioration. Nothing major there.
The shift in strike comes from the RIDB on Lincoln's forehead. Neat find. Have you tried Cuds on coins yet?
