I have accumulated the following Jefferson Nickels that appear to be the D over S variety. I am showing only the mint mark since the rest of the coin is generic. If I may, I would like some feedback, are they or aren't they? Are there potentials? Thanks.
I certainly don't see any, do you have examples? No. Don't bother. Too much trouble. They all have that "smooshed look". No apparent "S" below.
Meow honestly could not say there was a surefire RPM there. The coins are a bit too worn to see any subtle doubling.
