A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.
Seigniorage, also spelled seignorage or seigneurage, is the difference between the value of money and the cost to produce and distribute it. The term can be applied in two ways:
The Australian dollar is the official currency and legal tender of Australia, including all of its external territories, and three independent sovereign Pacific Island states: Kiribati, Nauru, and Tuvalu. In April 2022, it was the sixth most-traded currency in the foreign exchange market and as of Q4 2023 the seventh most-held reserve currency in global reserves.
Federal Reserve Notes are the currently issued banknotes of the United States dollar. The United States Bureau of Engraving and Printing produces the notes under the authority of the Federal Reserve Act of 1913 and issues them to the Federal Reserve Banks at the discretion of the Board of Governors of the Federal Reserve System. The Reserve Banks then circulate the notes to their member banks, at which point they become liabilities of the Reserve Banks and obligations of the United States.
A banknote – also called a bill, paper money, or simply a note – is a type of negotiable promissory note, made by a bank or other licensed authority, payable to the bearer on demand. Banknotes were originally issued by commercial banks, which were legally required to redeem the notes for legal tender when presented to the chief cashier of the originating bank. These commercial banknotes only traded at face value in the market served by the issuing bank. Commercial banknotes have primarily been replaced by national banknotes issued by central banks or monetary authorities.
Legal tender is a form of money that courts of law are required to recognize as satisfactory payment for any monetary debt. Each jurisdiction determines what is legal tender, but essentially it is anything which when offered ("tendered") in payment of a debt extinguishes the debt. There is no obligation on the creditor to accept the tendered payment, but the act of tendering the payment in legal tender discharges the debt.
Large denominations of United States currency greater than $100 were circulated by the United States Treasury until 1969. Since then, U.S. dollar banknotes have been issued in seven denominations: $1, $2, $5, $10, $20, $50, and $100.
The United States one-dollar bill (US$1), sometimes referred to as a single, 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. The reverse design of the present dollar debuted in 1935, and the obverse in 1963 when it was first issued as a Federal Reserve Note.
Notaphily is the study and collection of paper currency, and banknotes. A notaphilist is a collector of banknotes or paper money, particularly as a hobby.
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 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.
Gold certificates were issued by the United States Treasury as a form of representative money from 1865 to 1933. While the United States observed a gold standard, the certificates offered a more convenient way to pay in gold than the use of coins. General public ownership of gold certificates was outlawed in 1933 and since then they have been available only to the Federal Reserve Banks, with book-entry certificates replacing the paper form.
National Gold Bank Notes were National Bank Notes issued by nine national gold banks in California in the 1870s and 1880s and redeemable in gold. Printed on a yellow-tinted paper, six denominations circulated: $5, $10, $20, $50, $100, and $500. A $1,000 note was designed and printed but never issued. During the issuing period of national gold banks (1871–83), the U.S. Treasury issued 200,558 notes totaling $3,465,240. Today, National Gold Bank Notes are rare in the higher denominations with condition generally falling in the good-to-fine range. Approximately 630 National Gold Bank Notes are known to exist, and roughly 20 grade above "very fine".
The Confederate States dollar was first issued just before the outbreak of the American Civil War by the newly formed Confederacy. It was not backed by hard assets, but simply by a promise to pay the bearer after the war, on the prospect of Southern victory and independence. As the Civil War progressed and victory for the South seemed less and less likely, its value declined. After the Confederacy's defeat, its money had no value, and individuals and banks lost large sums.
Fractional currency, also referred to as shinplasters, was introduced by the United States federal government following the outbreak of the Civil War. These low-denomination banknotes of the United States dollar were in use between August 21, 1862, and February 15, 1876, and issued in denominations of 3, 5, 10, 15, 25, and 50 cents across five issuing periods. The complete type set below is part of the National Numismatic Collection, housed at the National Museum of American History, part of the Smithsonian Institution.

Greenbacks were emergency paper currency issued by the United States during the American Civil War that were printed in green on the back. They were in two forms: Demand Notes, issued in 1861–1862, and United States Notes, issued in 1862–1865. A form of fiat money, the notes were legal tender for most purposes and carried varying promises of eventual payment in coin but were not backed by existing gold or silver reserves.
Bills of credit are documents similar to banknotes issued by a government that represent a government's indebtedness to the holder. They are typically designed to circulate as currency or currency substitutes. Bills of credit are mentioned in Article One, Section 10, Clause One of the United States Constitution, where their issuance by state governments is prohibited.
The Treasury Note was a type of representative money issued by the United States government from 1890 until 1893 under authority of the Sherman Silver Purchase Act in denominations of $1, $2, $5, $10, $20, $50, $100 and $1,000. It was issued in two series: an 1890 series with $1, $2, $5, $10, $20, $100 and $1,000 denominations, and an 1891 series that added the $50 denomination. A $500 note was designed but never issued.
A silver certificate is a certificate of ownership that silver owners hold instead of storing the actual silver. Several countries have issued silver certificates, including Cuba, the Netherlands, and the United States. Silver certificates have also been privately issued by various mints and bullion companies. One example was the Liberty Dollar issued by NORFED from 1998 to 2009.
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.
