The listing actually states it is a fake. I put in $4 because I wanted to start working on my "fake knowledge" and maybe share with Steve Caruso. But I was shocked that it went for $65.

The pictures are not great so you may not see that there are no lines in the III. I double checked the patterns for that year and there were no 3CN patterns.
Here is the title of the listing:
1878
Three Cent PIECE (NICKEL) PROOF PROBABLE FAKE


Did I miss an awesome steal or did the bidding just get carried away?
