Who designed the US dollar?
United States one-dollar bill
The United States one-dollar bill ($1) is a denomination of United States currency. An image of the first U.S. President (1789–97), George Washington, based on a painting by Gilbert Stuart, is currently featured on the obverse (front), and the Great Seal of the United States is featured on the reverse (back). The one-dollar bill has the oldest overall design of all U.S. currency currently being produced (The current two-dollar bill obverse design dates from 1928, while the reverse appeared in 1976). The obverse design of the dollar bill seen today debuted in 1963 (the reverse in 1935) when it was first issued as a Federal Reserve Note (previously, one dollar bills were Silver Certificates).
Mercury dime
The Mercury dime is a ten-cent coin struck by the United States Mint from late 1916 to 1945. Designed by Adolph Weinman and also referred to as the Winged Liberty Head dime, it gained its common name as the obverse depiction of a young Liberty, identifiable by her winged Phrygian cap, was confused with the Roman god Mercury. Weinman is believed to have used Elsie Stevens, the wife of lawyer and poet Wallace Stevens, as a model. The coin's reverse depicts a "fasces", symbolizing unity and strength, and an olive branch, signifying peace.
