Why did the us not print paper money in 1936?

Answer 1

The dates on US paper money are "series" dates rather than printing dates. A series date is changed when a new design is adopted; since 1974 the series date also changes when a new Treasury Secretary takes office.

While it appears that no bills are printed during years in between series date changes, production actually continues with the original date regardless of the calendar year. In fact, because the 1935 series of $1 bills was never redesigned, they were printed into the early 1960s with that date!
