As of today, any $100 bill dated 2015 or 2016 is counterfeit.  The date appearing on the face of the bill is the series date (the year the design was adopted) and not the year the bill was printed.  That has been the convention since 1869.  The most current $100 design is Series 2009 A.  Nowhere on a $100 bill, or any other Federal Reserve Note, is the date the bill was printed. The Fed printed 1.28 billion $100 bills in 2015 and has ordered the U.S. Treasury Department’s Bureau of Engraving and Printing to produce 1.52 billion for 2016.
