Error Coin Information Exchange
- It's not often that I address a post this old (8/24/2001). However,
I did get to see once again the 1962 cent that I thought had four
sets of raised, parallel profiles of Lincoln. My initial impression
based on a brief examination at a coin show was wrong. It actually
had four sets of INCUSE images. It was a shifted cap strike. The
coin had been struck through a die cap that had experienced three
previous shift-and-strike events.
So now I'm back to two sets of expansion ripples as the maximum I've
yet come across. I still don't have an explanation that I'm
comfortable with, though.
