Hi - I am trying to check out the value or find out anything interesting about a couple of $1 bills I have from 1973, but everything I can find about the serial number doesn't seem to line up. They start with BCJ followed by 7 numbers. As far as I can tell, they should have only two letters? And I haven't seen any reference to $1 notes from that series starting with BC? Is it just that they are really common, so nobody ever lists these prefixes on price lists, etc?
Thanks!
