There have been 15 defunct National Basketball Association franchises. The National Basketball Association (NBA) is a professional men's basketball league, consisting of thirty teams in North America (twenty-nine in the United States and one in Canada). Nine of the league's defunct teams played in only one NBA season. The Anderson Packers, the original Denver Nuggets, the Indianapolis Jets, the Sheboygan Red Skins (arena pictured), and the Waterloo Hawks had played in the National Basketball League before joining the NBA, while the original Baltimore Bullets had played in the American Basketball League. The Packers, Red Skins, and Hawks left the NBA for the National Professional Basketball League, and are the only defunct teams to have ceased to exist in a league other than the NBA. The original Bullets were the last defunct team to leave the NBA, having left during the 1954–55 season, and are the only defunct team to have won an NBA championship. (Full list...)

Greenbacks were paper currency issued by the Union government from 1862 to 1865, during the American Civil War. Issued in denominations of 1, 2, 5, 10, 20, 50, 100, 500 and 1000 dollars, they were legal tender but were not backed by gold or silver. The obverse of the banknotes was printed in green, black and red, while the reverse was printed in green, giving the notes their popular name of "greenbacks". They were signed by Lucius E. Chittenden, Register of the Treasury, and Francis E. Spinner, Treasurer of the United States.

This picture shows a ten-dollar greenback issued in 1863, featuring a portrait of Abraham Lincoln, the president at the time, and a bald eagle, the national bird of the United States, on the obverse. This banknote is part of the National Numismatic Collection at the Smithsonian Institution's National Museum of American History.

Other denominations: $1, $2, $5, $20, $50, $100, $500, $1000
