The United States one-dollar bill ($1) is a denomination of United States currency. The first U.S. President (1789–97), George Washington, painted 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 design of all U.S. currency currently being produced. The design seen today debuted in 1963 when it was first issued as a Federal Reserve Note (previously, one dollar bills were Silver Certificates).
The inclusion of the motto, "In God We Trust," on all currency was required by law in 1955, and first appeared on paper money in 1957.
An individual dollar bill is also less formally known as a one, a single, a buck, a bone, and a bill.
The Federal Reserve says the average life of a $1 bill in circulation is 5.8 years before it is replaced because of wear. Approximately 42% of all U.S. currency produced in 2009 were one-dollar bills.

In 1929, all currency was changed to the size with which we are familiar today. The first one-dollar bills were issued as silver certificates under Series of 1928. The treasury seal and serial numbers were dark blue. The obverse was nearly identical to the Series of 1923 $1 Silver Certificate, but the treasury seal featured spikes around it and a large gray ONE replaced the blue "1 DOLLAR." The reverse, too, had the same border design as the Series of 1923 $1 bill, but the center featured a large ornate ONE superimposed by ONE DOLLAR. These are commonly known as "Funnybacks" due to the rather odd-looking "ONE" on the reverse. These $1 Silver Certificates were issued until 1934.
