Opinions on this 1988 Lincoln cent which appears to have IMO a plating blister on the left of the Lincoln memorial ?
With all of the environmental damage and staining I strongly suspect that small areas of the plating were compromised and there is zinc rot (corrosion) under those spots.
A fart from a zinc bubble that hasn't popped yet, anomaly number 979,988. Stick with pre 1982 at least you will have true copper, no pun intended. Thanks for sharing and good luck.
