when did they stop making thousand dollar bills
Large denominations of United States currency Although they are still technically legal tender in the United States, high-denomination bills were last printed on December 27, 1945, and officially discontinued on July 14, 1969, by the Federal Reserve System,[9] due to 'lack of use'. The $5,000 and $10,000 effectively disappeared well before then.[nb 1]
Dollar coin (United States) Dollar coins have never been very popular in the United States since the removal of specie coins from circulation. Despite efforts by the government to promote their use, such as the Presidential $1 Coin Program, most Americans currently use the one-dollar bill rather than dollar coins.[2] For this reason, since December 11, 2011, the Mint has not produced dollar coins for general circulation, and all dollar coins produced after that date have been specifically for collectors and can be ordered directly from the Mint, and pre-2012 circulation dollar coins are able to be obtained from most U.S. banks.[3][4]
Hundreds and thousands Hundreds and thousands used incorrectly instead of hundreds of thousands to mean "an indefinite but emphatically large number".
