The 68 Kennedy came from the bank. The W (a Lowell) and the 64 quarter came from the laundromat. And the 51 nickel came from a bankroll. I think the 51 is a proof but I'm not sure. The 64 is in incredible condition, almost flawless. I don't think it has seen much circulation at all. ADDENDUM: I just got home from the grocery store and found this in the coinstar:
what is the mint mark on the 1951 Jefferson nickel? it is a proof! and that 1964 quarter is amazing! and the w one too! really cool find!
