The United States one-dollar banknote, has been the lowest value denomination of United States paper currency since the discontinuation of U.S. fractional currency notes in 1876. 
An image of the first U.S. president (1789–1797), George Washington, based on the Athenaeum Portrait, a 1796 painting by Gilbert Stuart, is currently featured on the obverse, and the Great Seal of the United States is featured on the reverse. The one-dollar bill has the oldest overall design of all U.S. currency currently being produced.
Silver certificates are a type of representative money issued between 1878 and 1964 in the United States as part of its circulation of paper currency. They were produced in response to silver agitation by citizens who were angered by the Fourth Coinage Act, which had effectively placed the United States on a gold standard. The certificates were initially redeemable for their face value of silver dollar coins and later for one year from June 24, 1967, to June 24, 1968 in raw silver bullion. Since 1968 they have been redeemable only in Federal Reserve Notes and are thus obsolete, but still valid legal tender at their face value and thus are still an accepted form of currency.
George Washington (1732 – 1799), was an American military officer, statesman, and Founding Father who served as the 1st president of the United States from 1789 to 1797.
