How many US 2 dollar bills are printed every year?

Because $2 bills are the least-used denomination, they're printed on an as-needed basis instead of every year.

The Bureau of Engraving and Printing publishes how many bills are printed in each fiscal year. They don't show specifically which date(s) are printed on the bills but it's possible to infer that from the series year.

1996: 51,200,000 (1995 series)

1997: 102,400,000 (1995 series)

2004: 121,600,000 (2003 series)

2006: 230,400,000 (2003-A series)

2012: (incomplete, 2009 series)

The gradual increase in demand has been attributed to a number of different factors, including the use of the denomination by group promotions, for payment of transit fares that have pushed to or over $2, and simply to increased awareness in a few parts of the country.

In any case there is no truth to any of the many rumors that the denomination is rare, has been discontinued, or is in some way connected with crime or religious curses.
