Federal Reserve Notes, also United States banknotes, 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 United States Note, also known as a Legal Tender Note, is a type of paper money that was issued from 1862 to 1971 in the United States. Having been current for 109 years, they were issued for longer than any other form of U.S. paper money. They were known popularly as "greenbacks", a name inherited from the earlier greenbacks, the Demand Notes, that they replaced in 1862. Often termed Legal Tender Notes, they were named United States Notes by the First Legal Tender Act, which authorized them as a form of fiat currency. During the early 1860s the so-called second obligation on the reverse of the notes stated:
This Note is a Legal Tender for all debts public and private except Duties on Imports and Interest on the Public Debt; and is receivable in payment of all loans made to the United States.
Currency bill tracking is the process of tracking the movements of banknotes, similar to how ornithologists track migrations of birds by ringing them. It is usually facilitated by any one of a number of websites set up for the purpose, which can track currency among the users of that website. A user may register a bill by entering its serial number, and if someone else has already registered the bill, then the "route" of the bill can be displayed.
EuroBillTracker (EBT) is a website designed for tracking euro banknotes. It was inspired by the US currency bill tracking website Where's George? The aim is to record as many notes as possible to know details about their distribution and movements, follow it up, like where a note has been seen in particular, and generate statistics and rankings, for example, in which countries there are more tickets. EuroBillTracker has registered over 220 million notes as of September 2023, worth more than €4 billion.
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.
Where's Willy? is a website that tracks Canadian paper money, most commonly $5 bills, but also higher denominations. "Where's Willy" is free, supported by users who pay a fee for extra features. The name Willy refers to Sir Wilfrid Laurier - the seventh Prime Minister of Canada whose portrait appears on the $5 banknote.
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.
The krone was the official currency of Austria-Hungary from 1892 until the dissolution of the empire in 1918. The subunit was one hundredth of the main unit, and was called a Heller in the Austrian and a fillér in the Hungarian part of the Empire.
DoshTracker was a currency bill tracking website that allows pound sterling banknotes to be tracked around the United Kingdom and abroad. Originally launched in 2001, it was relaunched in 2012.
Banknotes that are no longer in issue in Canada, and are being removed from circulation, are said to be "withdrawn from circulation".
Counterfeit money is currency produced outside of the legal sanction of a state or government, usually in a deliberate attempt to imitate that currency and so as to deceive its recipient. Producing or using counterfeit money is a form of fraud or forgery, and is illegal in all jurisdictions of the world. The business of counterfeiting money is nearly as old as money itself: plated copies have been found of Lydian coins, which are thought to be among the first Western coins. Before the introduction of paper money, the most prevalent method of counterfeiting involved mixing base metals with pure gold or silver. Another form of counterfeiting is the production of documents by legitimate printers in response to fraudulent instructions. During World War II, the Nazis forged British pounds and American dollars. Today, some of the finest counterfeit banknotes are called Superdollars because of their high quality and imitation of the real US dollar. There has been significant counterfeiting of Euro banknotes and coins since the launch of the currency in 2002, but considerably less than that of the US dollar.
Counterfeiting of the currency of the United States is widely attempted. According to the United States Department of Treasury, an estimated $70 million in counterfeit bills are in circulation, or approximately 1 note in counterfeits for every 10,000 in genuine currency, with an upper bound of $200 million counterfeit, or 1 counterfeit per 4,000 genuine notes. However, these numbers are based on annual seizure rates on counterfeiting, and the actual stock of counterfeit money is uncertain because some counterfeit notes successfully circulate for a few transactions.
The currencies of Puerto Rico closely follow the historic development of Puerto Rico. As a Province of Spain and a territory of the United States, Puerto Rico was granted the use of both foreign and provincial currencies. Following the Spanish colonization in 1502, Puerto Rico became an important port, with its own supply of gold. However, as the mineral reserves ran empty within the century, the archipelago's economy suffered. The Spanish Crown issued the Situado Mexicano, which meant that a semi-regular shipment of gold from the Viceroyalty of New Spain would be sent to the island, as a way to provide economic support. Between 1636 and 1637, Philip IV of Spain imposed a tax which had to be paid using a revenue stamp. Inspired by this, Puerto Rico began producing banknotes in 1766, becoming the first Overseas Province to print 8-real banknotes in the Spanish Empire and which in the Spanish government's approval of subsequent issues.
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 21 August 1862 and 15 February 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.
Money burning or burning money is the purposeful act of destroying money. In the prototypical example, banknotes are destroyed by setting them on fire. Burning money decreases the wealth of the owner without directly enriching any particular party. It also reduces the money supply and slows down the inflation rate.
Stamp Stampede is a grassroots campaign mobilizing people across the United States to stamp messages on American currency in support of passing a constitutional amendment to Get Money Out of Politics. Ben Cohen, the co-founder of Ben & Jerry's ice cream, spearheaded the campaign. They promote stamping through the distribution of rubber stamps, public stamping activities and national tours in the Stamp Mobile. The rubber stamps include different messages, such as: "Money is not free speech," "Not to be used for bribing politicians," "Corporations are not people; amend the Constitution," and "The system isn’t broken, it's fixed."
The copper-nickel three-cent piece, often called a three-cent nickel piece or three-cent nickel, was designed by US Mint Chief Engraver James B. Longacre and struck by the United States Bureau of the Mint from 1865 to 1889. It was initially popular, but its place in commerce was supplanted by the five-cent piece, or nickel.
