Received these at the bank today. Some folks in other countries complain about getting a 2006 or 2006A hundred (old series); well I'll raise you these two, both from the 1960s and still circulating. If we want to get into the weeds a little bit- only the 1963A is the true 1960s bill here (1963A $100s were printed between 1966 and 1969). The 1969A was printed sometime between 1971 and 1973. Anyhow, fun to see these still out and about from time to time. One other minor note- 1963A has the Treasury seal in Latin. However, in 1968 the seal was updated, and that's the one we see in English on the 1969A and on all present-day notes.
I always wondered why that was so. Unlike with coins, where they update the striking date every year. Didn't know that, will have to check it out, thanks !!!
Probably because it's not very efficient is my guess. Series typically change only when a treasury official takes office/leaves or a new administration comes in. For example, 1969, 1969A, 1969B and 1969C were all printed during Nixon's term (took office in 1969). The 1963 (and 1963A) series came about when Johnson took office, 1974 series was printed when Ford arrived, 1977 (and 1977A) when Carter arrived, 1981 when Reagan... and well, you get the idea. Interestingly enough, Series 1950 dominated for the longest time. Series 1950, 1950A, 1950B, 1950C, 1950D and even 1950E notes were printed well into the 1960s as well. I guess the treasury department really liked the year 1950.
The 1950 series used an earlier paper that had to be wetted before the printing process - the BEP used it's stocks of the paper until it ran out - they were used at the same times as the series 1963 until the stocks of wetted paper were used up in the mid 1960s
