Harriet Tubman, Alexander Hamilton To Grace U.S. Currency

A female face will soon grace the $20 bill, keeping U.S. founding father Alexander Hamilton on the $10 note, Treasury Secretary Jack Lew is expected to announce late Wednesday.

The historical woman chosen to go on the bill: Harriet Tubman, the African American abolitionist most famous for her role in helping slaves escape through the "Underground Railroad."

Tubman, a former slave, will be replacing Andrew Jackson, the nation's seventh president and a former slave owner.

A Treasury spokesperson announced that Lew will make the announcement late Wednesday, after markets close.

The original plan for getting a female face on U.S. currency has changed drastically in recent months.

The agency was initially expected to announce which woman would be appearing on the $10 bill by the end of last year - a move that drew fierce backlash in part because of Alexander Hamilton's recent popularity.

Hamilton, the nation's first Treasury secretary, enjoyed a resurgence as a result of the hugely successful hip hop musical based on his life.

CBS News confirmed Hamilton would remain the face of the $10 bill earlier this week.

The new ten dollar bill will be unveiled in 2020, going into circulation shortly after. The timing of the new twenty dollar bill's production has not yet been announced.
