In order to finance the Civil War, Congress authorizes the U.S. Department of the Treasury to issue non-interest-bearing Demand Notes. These notes earn the nickname “greenbacks” because of their color. All U.S. currency issued since 1861 remains valid and redeemable at full face value.

In the first significant design change since the 1920s, U.S. currency is redesigned to incorporate a series of new counterfeit deterrents. Issuance of the new banknotes begins with the $100 note in 1996, followed by the $50 note in 1997, the $20 note in 1998, and the $10 and $5 notes in 2000.
