On April 20, 2016, Treasury Secretary Jacob J. Lew announced that Harriet Tubman will be the new face of the $20 bill, replacing Andrew Jackson. However, the seventh president wasn't the first face of the $20. The 1864 $20 banknote showed Lady Liberty, and before Jackson made his way onto the bill in 1928, it featured presidents George Washington and Grover Cleveland. The Tubman design of the $20 bill is set to be unveiled in 2020, and will enter circulation thereafter. The $5 and $10 bills are also getting a facelift -- the backs of each will be redesigned. The $5 will feature historical figures associated with the Lincoln Memorial, including Dr. Martin Luther King Jr., who delivered his "I Have a Dream" speech there. The $10 will now feature leaders of the suffrage movement, including Sojourner Truth and Susan B. Anthony. These changes constitute the biggest makeover U.S. currency has seen since the 1920s.
