Should woman go on $10 bill or $20 bill?

Treasury officials declined to comment Monday on the specifics of a CNN report that Lew has decided to keep Hamilton on the $10 bill, and instead replace Jackson's portrait on the $20 bill with a woman who represents the struggle for racial equality.

CNN, quoting a senior government source, said that women will also be honored on the $10 bill, the denomination next up to for redesign, with a mural-style depiction of the suffrage movement that will replace the current drawing of the Treasury building.

Lew announced last summer that the government was going to incorporate a woman on the $10 bill, which would mark the first appearance of a female portrait on U.S. paper currency in 100 years.

Susan Ades Stone, the executive director of Women on 20s, said while her group has been campaigning for the change, it is concerned that the change could delay introduction of a woman on the currency for more than a decade.

In a poll conducted last year by Women on 20s, Harriet Tubman, an African-American abolitionist and one of the leaders' of the Underground Railroad, was the top vote getter.
