Move over, George Washington. Eleanor Roosevelt might be taking your spot on the $1 bill.

A young girl's letter to President Obama sparked a discussion about the possibility of adding women's faces on American currency. Obama mentioned the letter at an appearance Wednesday in Kansas City, Mo.

"And then she gave me like a long list of possible women to put on our dollar bills and quarters and stuff, which I thought was a pretty good idea," Obama said.So did the Internet.

Soon, there was Oprah on a $20 bill thanks to New York Magazine, Harriet Tubman on a $100 bill from The New Republic and questions across the Twitterverse on why Beyoncé doesn't have her own bill (she is, after all, called Queen Bey).

Though there isn't currently a woman on a paper note, there was once, in 1886. Martha Washington appeared on the $1 silver certificate, which could be redeemed for silver coins.

Women have graced two dollar coins made mostly of copper. Susan B. Anthony is on one that looks something like a quarter, and Sacagawea is on what's known as the "golden dollar." Those coins remain in circulation, but are not currently in production.
