I got these in a group of about 150 1963-1977 notes from the credit union a few years ago. Each has some very light folding/handling that keeps them out of the CU range, so I'm guessing they're somewhere around AU50-AU55. I really like the high serial number B99877974C on the middle note. At the time, the BEP still issued notes up to 99999999. Just thought I'd share with the group
