United States Note in the context of "United States one-hundred-dollar bill"

From 1775 to 1779, the Continental Congress issued Continental currency banknotes. Then there was a period when the United States just used gold and silver, rather than paper currency. In 1812, the US began issuing Treasury Notes, although the motivation behind their issuance was funding federal expenditures rather than the provision of a circulating medium. In 1861, the US began issuing Demand Notes, which were the first paper money issued by the United States whose main purpose was to circulate. And since 1914, the US has issued Federal Reserve Notes.

Since 1971, Federal Reserves Notes have been the only banknotes of the United States dollar that have been issued. But at some points in the past, the United States had multiple different types of banknotes, such as United States Notes (1862–1971), Interest bearing notes (1863-1865), and Gold certificates (1865–1934).

The United States two-dollar bill (US$2) is a current denomination of United States currency. A portrait of Thomas Jefferson, the third president of the United States (1801–1809), is featured on the obverse of the note. The reverse features an engraving of John Trumbull's painting Declaration of Independence (c. 1818).

Throughout the $2 bill's pre-1929 life as a large-sized note, it was issued as a United States Note, a National Bank Note, a Silver Certificate, a Treasury or "Coin" Note, and a Federal Reserve Bank Note. In 1928, when U.S. currency was redesigned and reduced to its current size, the $2 bill was issued only as a United States Note. Production continued until 1966 (1967), when United States Notes were phased out; the $2 denomination was discontinued until 1976, when it was reissued as a Federal Reserve Note, with a new reverse design. The obverse design of the $2 bill is the oldest of all current US currency.

A Demand Note is a type of United States paper money that was issued from August 1861 to April 1862 during the American Civil War in denominations of 5, 10, and 20 US$. Demand Notes were the first issue of paper money by the United States that achieved wide circulation, albeit only for a short time. The U.S. government placed Demand Notes into circulation by using them to pay expenses incurred during the Civil War including the salaries of its workers and military personnel.

Because of the distinctive green ink on their reverse, and because state-chartered bank and Confederate notes of the day typically had blank reverses, the Demand Notes were nicknamed "greenbacks", a name later inherited by United States Notes and Federal Reserve Notes. The obverse of the Demand Notes contained familiar elements such as the images of a bald eagle, Abraham Lincoln, and Alexander Hamilton, though the portraits used on Demand Notes are different from the ones seen on U.S. currency today.
