<P> In a campaign called "Women on 20s", selected voters were asked to choose three of 15 female candidates to have a portrait on the $20 bill . The goal was to have a woman on the $20 bill by 2020, the centennial of the 19th Amendment which gave women the right to vote . Among the candidates on the petition were Harriet Tubman, Eleanor Roosevelt, Rosa Parks, and Wilma Mankiller, the first female chief of the Cherokee Nation . </P> <P> On May 12, 2015, Tubman was announced as the winning candidate of that "grassroots" poll with more than 600,000 people surveyed and more than 118,000 choosing Tubman, followed by Roosevelt, Parks and Mankiller . </P> <P> On June 17, 2015, then - Treasury Secretary Jack Lew announced that a woman's portrait would be featured on a redesigned $10 bill by 2020, replacing Alexander Hamilton . However, that decision was reversed, at least in part due to Hamilton's surging popularity following the hit Broadway musical Hamilton . </P> <P> On April 20, 2016, Lew officially announced that Alexander Hamilton would remain on the $10 bill, while Andrew Jackson would be replaced by Tubman on the front of the $20 bill, with Jackson appearing on the reverse . Lew simultaneously announced that the five - and ten - dollar bills would also be redesigned in the coming years and put into production in the next decade . Steven Mnuchin, the current U.S. Treasury Secretary, said that he will not commit to putting Tubman on the twenty - dollar bill, explaining "People have been on the bills for a long period of time . This is something we'll consider; right now we have a lot more important issues to focus on ." </P>
