Counter-stamped(?) Nickel
Hi All,
Was doing my usual sifting and came across this nickel with an “F” stamped/embossed on the Monticello. I know it’s not an error, but I’m not familiar with this sort alteration. The coin itself is relatively old (1951) and the wear and grit built up into the stamp signals to me that it was done quite some time ago.
My research showed that two characters would be common because sometimes people would stamp their initials; which, based on where the “F” is stamped, seems like that may have been the intent?
Just curious. Thank you!
