Very nice find! Do you work at the bank or did a teller save that stuff for you rather than pull it from circulation and send it off to be destroyed.
Check those Series 34 $5 FRNs carefully. There could be a valuable mule or two. Also, if any of the 28 FRNs are series C or D, those are worth bucks, too. BTW - Nice find. I run a retail, mostly cash business, and figure $10,000,000 in cash has passed through in the thirty-odd years I've been there. I used to get 34's and 50's series FRN's a few times a year. Then a couple times a year. Then once in a coon's age. Then never.
