United States currency

United States currency. United States currency serves as the primary medium of exchange, unit of account, and store of value used in the United States. It encompasses banknotes and coins produced and managed by institutions such as the United States Department of the Treasury, the Federal Reserve System, the Bureau of Engraving and Printing, and the United States Mint. Monetary policy and currency stability are influenced by events and institutions including the Coinage Act of 1792, the Gold Standard Act, and crises such as the Panic of 1837 and the Great Depression.

History

The development of United States currency traces from colonial instruments like Continental Congress notes and provincial coins through federal statutes such as the Coinage Act of 1792 and the establishment of the United States Mint and Second Bank of the United States. Key episodes include the Civil War-era United States Note issuance, debates over the Free Silver movement, and legislative measures including the National Banking Acts and the Federal Reserve Act. International commitments and shifts—such as the Bretton Woods Conference, the Gold Reserve Act of 1934, and President Richard Nixon's decision in 1971—altered convertibility and global monetary arrangements. Financial crises and reforms—seen in the Panic of 1907, the Glass–Steagall Act, and responses to the 2007–2008 financial crisis—have repeatedly affected currency design, regulation, and public confidence.

Denominations and Design

Coin denominations produced by the United States Mint include the cent, the nickel, the dime, the quarter, the half dollar, and the dollar coin in various designs like the Sacagawea dollar and the Presidential $1 Coin Program. Banknotes issued by the Bureau of Engraving and Printing include the $1, $2, $5, $10, $20, $50, and $100 denominations featuring portraits of figures such as George Washington, Thomas Jefferson, Abraham Lincoln, Alexander Hamilton, Ulysses S. Grant, and Benjamin Franklin. Design elements reference artifacts and sites like the Great Seal of the United States, the United States Capitol, and the White House, and have evolved through series such as the 1928, 1957, and 1996 redesigns. Commemorative and special-issue coins and notes honor events and persons including the Lewis and Clark Centennial, the Bicentennial, and the Presidential $1 Coin Program.

Production and Issuance

Production of paper currency is carried out at facilities of the Bureau of Engraving and Printing in Washington, D.C. and Fort Worth, Texas, while coinage is struck at United States Mint facilities in Philadelphia, Denver, San Francisco, and West Point. The United States Department of the Treasury authorizes issuance in coordination with the Federal Reserve System, whose regional Federal Reserve Bank branches distribute notes and coins to depository institutions. Legal statutes such as the Coinage Act of 1873 and modern directives from the Secretary of the Treasury govern specifications, while collectors interact with programs like the United States Mint proof coinage and the Citizen Coinage Advisory Committee. Emergency measures, including those implemented during World War II and the COVID-19 pandemic, have affected production, allocation, and storage.

Circulation and Legal Tender

Banknotes designated Federal Reserve Notes are obligations issued by the Federal Reserve System and are recognized as legal tender under statutes enacted by the United States Congress. Coins minted by the United States Mint are likewise legal tender for debts and transactions. Internationally, the dollar is used in offshore markets and appears in arrangements such as those influenced by the International Monetary Fund and the World Bank. Monetary aggregates monitored by the Federal Reserve Board—including M1 and M2—reflect currency in circulation, deposits at institutions like JPMorgan Chase, Bank of America, and regional banks, and influence policy decisions at the Federal Open Market Committee. Issues of currency hoarding, cross-border use in territories like Puerto Rico and Guam, and parallel instruments such as gold certificates have influenced circulation patterns.

Counterfeiting and Security Features

Counterfeiting has long driven anti-counterfeiting measures, with legal responses found in statutes enforced by the United States Secret Service and prosecutions in federal courts such as the United States District Court for the Southern District of New York. Modern banknote security features include microprinting introduced in redesigns, color-shifting ink used on denominations such as the $100, security threads with embedded text, and watermarks matching portraits like Benjamin Franklin. Coin security includes reeded edges and bi-metallic or clad compositions used since changes prompted by the Coinage Act of 1965. Research collaborations with institutions like the Smithsonian Institution and universities have advanced anti-counterfeiting technologies, while major counterfeit incidents—investigated alongside agencies such as the Federal Bureau of Investigation and United States Postal Inspection Service—inform ongoing design updates and enforcement strategies.
