Small (and stupid propably) question. I know that wher you look at the series date and there is a letter printed next to or under the date that it is because of a minor revision in the design Now to be honest, i cant find any difrence in my notes. I have a 1957 Silver certificate, 1957 A Silver certificate, 1957 B Silver certificate. But what is the difrence?
The signatures should be different. 1957 Priest/Anderson 1957A Smith/Dillon 1957B Granahan/Dillon as seen here http://www.uspapermoney.info/general/chron_s.html
Design changes wouldn't be the only reason to change, or add an addendum onto the series year. This is also done becuase of signature changes, which would be the case with your silver certs. *edit* Steve beat me to it. Doh!
you are absolutely right. I have been looking over those notes every milimeter, exept the signatures to find a difrence (tought the sig's didnt change in the same year series) and could not find it. Thank you for the info.
