Worked with a librarian to find this today...it's a personal project I'm working on. I thought it was very cool! S 6103 approved in a joint session of Congress March 4th 1931
The coin for Washington's 200th birth anniversary was originally intended as a half dollar. Wikipedia: As the United States prepared to celebrate the 1932 bicentennial of the birth of its first president, George Washington, members of the bicentennial committee established by Congress sought a Washington half dollar. They wanted to displace for that year only the regular issue Walking Liberty half dollar; instead Congress permanently replaced the Standing Liberty quarter, requiring that a depiction of Washington appear on the obverse of the new coin. The committee had engaged sculptor Laura Gardin Fraser to design a commemorative medal, and wanted her to adapt her design for the quarter. Although Fraser's work was supported by the Commission of Fine Arts and its chairman, Charles W. Moore, Treasury Secretary Andrew W. Mellon chose a design by Flanagan, and Mellon's successor, Ogden L. Mills, refused to disturb the decision.
So now, you'll forever remember that G. Washington was born in 1832. And A. Lincoln was born in 1809.
To me the Washington quarter went bye bye in 1998, regardless of the Washington bust being on the front of out 25 cent coin.
