Aaron PattonRob and Paul,
Received my examples this AM.
The backs are modern (modern sping-pins).
No manufacturer. No union stamp.
Each has lite rusting around (a brass) rim.
Without knowing what I'm talking about....I'm guessing c1970s/1980s?
Will eagerly look forward to your (much more educated) opinions.
Have a good afternoon, Gentlemen..
Edit: for clarity + spelling
