I have been out of the loop fer too long. Didn't know about all these repunched dates & mint marks back when I was a dealer. I knew about the 42/41 dime (found one in circulation - my best find ever) and the 1955/1955 cent but not much more than that. Guess I will have to dig out a few "junk silver" coins I stashed away back in the 1980s. Maybe I'll get lucky again.
