I've looked over Chuck's 1980 cent, along with a similar-looking cent of the same date that is less seriously affected. Regrettably, they both appear to have been altered outside the Mint.
On the more severely affected coin, the evidence for fakery is as follows (some of this I've said before).
1. The pattern of ripples is unlike any other pattern of genuine
Die Deterioration I've come across.
2. While the surface texture is grossly affected, the thickness of the letters has hardly changed. With
Die Deterioration this severe, you'd expect gross expansion of the letters and a narrowing of the gap between the letters and the design rim.
2. The likelihood that both faces would show an identical pattern of distortion of equal severity is almost nil.
3. The surface color is unnatural-looking.
4. The clincher is that the odd texture appears on the edge at about 1:00. This will never be the case with geniune
Die Deterioration, as the collar does not develop this kind of wear. And even if it did, its appearance would not likely coincide with anything going on with the obverse or reverse face.
The second cent presents similar problems, including the repetition of an odd texture on the edge.
I don't know what was done to them, but their appearance is incompatible with a genuine error.
