I like to pride myself on the idea that I know just about everything about modern size paper money series 1928 onward. But what I surprisingly don't know, is how silver certificates and red seals were serial numbered. For an instance, what do I make out of a 1957 $1 SC with block A-B and then the same thing but block I-I? Does it just go kind of like FRN's, every time the first letter runs out of notes to print, they just move the second letter over? But then we would see notes like A-Y or something like that... And we don't. Any help would be great! I tried googling it but nothing came up. Thanks in advanced! -Travis
From what I understand (and I could be wrong)... Basically, on earlier small size notes (silver certs, gold certs, USNs), the prefix letter was changed before the suffix. On Federal Reserve Notes, the prefix is dependent on the Federal Reserve Bank, i.e. A-Boston, B-New York, etc. and only the block letter (suffix) changes. That's why the prefix and suffix combos seem so different, as you noted. Here is a page that can explain it better than I can: http://www.capcurr.com/anatomy/serial.htm Hope that helps a bit. I'm sure Numbers may also have some insight and explanation on the process.
