This is pretty awesome:

Former slave Harriet Tubman will replace former President Andrew Jackson on the $20 bill, Treasury Secretary Jack Lew is expected to announce on Wednesday.

...

Alexander Hamilton, who created the Treasury Department, was originally targeted for replacement, but will remain on the $10 bill after public outcry.

Critics called for Jackson to be replaced based on his decision to violently remove Native Americans from their ancestral lands. He is likely to remain on the back of the bill, according to Politico.

Hamilton has gained popularity recently, thanks to the Broadway hit musical based on his life. Lin-Manuel Miranda, who created and stars in 'Hamilton', was a leading lobbyist for the former Treasury secretary to remain on the $10.

Although, if they keep changing what our money looks like, i'm going to be so confused. As it is, half the time i don't think the new quarters are real currency.
