"The buck stops here."
— sign on President Harry Truman's desk note
the article on American Currency
, which evolved independently.
The standard unit of American money is called the dollar
, presumably from the German word "Taler" which was used for various now obsolete currencies and is originally derived from "Joachimsthal", a town in Bohemia where coins were minted. More directly, the original U.S. dollar was based on the Spanish eight-real coin, called the Spanish Dollar (and occasionally the Dollero
) because of its resemblance to the taler
coin. Even though the north American colonies belonged to Great Britain, the Spanish Dollars were more popular there because of their finer silver.
The dollar is subdivided into 100 individual units, called cents
. Each cent is in turn further divided into 10 mills
, a unit of currency largely rendered hypothetical through inflation (except in the price of gasoline, although property-tax rates are often expressed in mills, hence the name mill levy
, or if you're a Michigander, "millages"), of which there are 1000 in a dollar.
The currently circulating coins are:
|Official name||Colloquial name||Value|
| cent || penny || 1¢ |
| nickel five cent piece || nickel || 5¢ |
| dime || dime || 10¢ |
| quarter dollar || quarter || 25¢ |
| half dollar* || 50 cent piece || 50¢ |
| dollar* || dollar || $1 |
(*) The half dollar and dollar coin are rarely seen in circulation.
: Officially called the cent. Each cent is one one hundredth of a dollar, and comes in the form of a small coin formerly made of bronze, but since 1981 made of zinc with a copper coating. In the early 1800s the one-cent piece was a very large coin, mid-way in size between the quarter and the half-dollar, but by the 1850s copper had become valuable enough that there was now more than a cent's worth of copper in a one-cent coin — the solution was to shrink it to its modern size, add 12% nickel to "make up for" the sharp reduction in size, and then remove this added nickel content a few years later when no one was looking. A similar dilemma faced the coin in 1981, when almost all of the copper had to be replaced with (much cheaper) zinc, and is facing the coin again today as even the price of zinc now outstrips the value of the penny. It's had Abraham Lincoln's profile on the front since 1909 (the 100th anniversary of his birth), when it replaced the classic "Indian Head" penny. The back has held various designs over that same period; the "wheat ear" design (1909-1958), the Lincoln Memorial (1958-2008), four images celebrating Lincoln's life and accomplishments for his bicentennial (2009), and the current "Union Shield" (2010-).
The change from bronze to copper-plated zinc in 1981 occurred because, thanks to inflation and the demand for copper to make electrical wires, the bronze cent contained more
than one cent's worth of metal. As of 2013, even zinc is now worth more than the face value of the cent. American voters are highly resistant to getting rid of the penny, so even cheaper materials are currently under investigation. In the mean time, U.S. law forbids these coins from being melted down, or from being shipped overseas in large quantities.
Officially called the nickel five-cent piece, to distinguish it from nickel three-cent pieces minted in the 1800s. Despite its name, 75% of its weight is made out of copper — only 25% is actual nickel metal. It's had Thomas Jefferson on the front since 1938 (replacing the "Buffalo Nickel"). The back has shown Jefferson's home, Monticello, for that entire period except during 2004 and 2005, when a set of four "Westward Journey" commemorative designs were used to celebrate the 200th anniversary of the Lewis and Clark expedition that Jefferson authorized.
Like the cent, the metals that the nickel is made out of are now (in 2013) worth more than its face value. A new, cheaper alloy may be in the works.
Officially called the dime. That's right. "Dime" is an official currency unit in the Federal monetary system, just like "dollar" and "cent" are. The word comes from the French disme
, meaning tenth — it's one-tenth of a dollar, or ten cents. Until 1965, dimes were composed of 90% silver, which is why they are smaller than nickels and pennies. It's also why the coin has a "reeded edge" — the vertical grooves carved into the edge made it easy to tell if someone had shaved a little bit of silver off the outside of the coin. The dime has had Franklin Delano Roosevelt's profile on the front since 1946, a year after he died, and a tails-side design derived from the Roosevelt family coat-of-arms.
Officially called the quarter dollar, worth 25 cents. Until 1965, quarters were composed of 90% silver, but today they're "copper-nickel clad", meaning they have an inner layer of copper "clad" in two outer layers of the same alloy that the nickel coin (above) is made of. It's had George Washington's profile on the front since 1938. Until 1999, these coins featured an eagle on the tails-side except for the bicentennial commemorative design used on the tails-side coins minted in 1975
through 1976 (even though the bicentennial year was strictly only
'76) which instead featured a likeness of a Colonial drummer, along with a flaming torch surrounded by 13 five-pointed stars representing the original thirteen colonies, those commemorative coins replaced the heads-side year-mark with a dual-year "1776-1976" numbering. Starting in 1999, a series of multiple tails-side designs commemorating each of the fifty states were issued, followed subsequently by a 51st design for Washington, DC
and a quintet of designs following that to provide one for each of the five United States territories populous enough to merit non-voting Congressional representatives: Puerto Rico, Guam, American Samoa, the United States Virgin Islands, and the Commonwealth of the Northern Mariana Islands. Once those series were completed, a (still ongoing) series of designs commemorating the United States' National Parks was introduced. These coin series were introduced in hopes of promoting public interest in coin collecting, and have proven wildly successful in that regard.
Officially called the half dollar. At some points in American history, this coin was actually more popular than the quarter. Like the dime and quarter, it was made of 90% silver until 1965, but unlike the dime and quarter it switched to a "copper-silver clad" configuration in 1965, resulting in people hoarding them in anticipation of rising silver prices. The composition switched to the same copper-nickel clad configuration as the dime and quarter in 1971, but by then it was too late. The coin fell almost completely out of favor, and to this day no vending machines (other than post office vending machines) accept the half dollar coin any more. It's had John F. Kennedy's profile on the front since 1964, the year after his assassination. Before then, it had featured a profile of Benjamin Franklin, whose likeness still graces the $100 bill to this day. The half-dollar coin features an eagle on the tails-side except for the bicentennial commemorative design used on the tails-side coins minted in 1975
through 1976 (even though the bicentennial year was strictly only
'76) consisting of Independence Hall, those commemorative coins replaced the heads-side year-mark with a dual-year "1776-1976" numbering.
Officially called the dollar
. Prior to 1979, it was a huuuuge
honkin' coin, with twice the weight of a 50-cent piece; this was due to its legacy of being made out of 90% silver, just like the dime, quarter, and half dollar were. To this day, these old large-sized dollar coins are still called "silver dollars", even though they stopped being made out of silver in 1971, the same year that the design was changed to a heads-side profile of Dwight Eisenhower
with a tails-side design based on the Apollo 11 mission patch
except for the bicentennial commemorative design used on the tails-side coins minted in 1975
through 1976 (even though the bicentennial year was strictly only
'76) featuring a likeness of the Liberty Bell superimposed on an image of the moon, those commemorative coins replaced the heads-side year-mark with a dual-year "1776-1976" numbering. Starting in 1979, a new, smaller dollar coin appeared sporting Susan B. Anthony's profile on the front. These were not only about the same size as a quarter, they also had the same copper-nickel clad construction and reeded edge as a quarter, making them easy to confuse in loose change. In 2000, the mint attempted to remedy this by introducing the "gold" (really manganese brass) dollar coin featuring Sacagawea's picture on the front. By this time, though, most Americans had gotten out of the habit of carrying change pouches around, and eminently preferred the paper dollar, so even this new easy-to-distinguish dollar coin never caught on. From 2007-2011, an attempt was made to revive interest in this coin by putting all of the U.S. presidents on them in chronological order so as to release a series with the intent being to use coin-collecting as a hobby to garner public support for the $1 coin, but this worked too
well when people showed more interest in collecting the series than in using it as money
and the program stopped at James A. Garfield.
It's worth noting that Canadian coins come in the same size, color, and denominations as Americans until you get to one dollar. The dollar coin, called a "Loonie" because of the loon bird picture on one of its faces. Unlike the American efforts, the Canadian government moved decisively to get it accepted, such as giving it a golden colour to make it look valuable while immediately discontinuing the $1 paper bank note; as a result, the Canadian public quickly accepted it without hesitation. They also have a $2-coin called a "toonie" that's bimetallic, with a central disc of a brass alloy encased in a silvery-colored outer ring. They're traditionally worth less and weigh less than American coins but are usually interchangeable to all but the most nitpicky cashiers and vending machines, and they draw less attention from cashiers the closer you get to the Canadian border. In some border states (e. g. Michigan) it's not unusual for up to half the change in a local's pocket to be Canadian. In addition, the Canadian government, recognizing the worthlessness of the penny nowadays, discontinued it in February 2013.note
As an artifact of their origins as bullion, the dime, quarter, half-dollar, and dollar are interchangeable by weight. In other words, ten dimes, four quarters, two half dollars, and one dollar coin all have the same currency value ($1) and the same weight (24.624 grams when they were 90% silver, 22.68 grams with the current copper/nickel composition).
When the British colonists came to America, their money was originally the good old-fashioned Old British Money
—pounds, shillings, and pence. However, British mercantilist policy in the 17th and 18th centuries meant that British hard currency in the form of gold and silver coins was always hard to come by in the colonial period, and so the colonists tended to look elsewhere for their preferred medium of exchange. As luck would have it, the Spanish had a giant mint at Mexico City pumping out pesos
worth eight reales
made of Mexican and South American silver. British Americans involved in the semi-illegal trade with Latin America brought back lots of this stuff from their trading jaunts and pretty soon the Spanish coins were pretty standard currency throughout the Colonies. These peso
coins eventually became the basis for modern American currency—but under a different name.
You see, the peso
was made to the specifications of a coin originally minted in a town in Central Europe (to be precise, Bohemia, then ruled by Austria, now in the Czech Republic) called Joachimsthal (Jáchymov in the modern Czech). Joachimsthal was in a major mining area, with many metals known, but it was particularly known for the high quality of its silver. When the Austrian Habsburg dynasty married into the Spanish royal family and took the country over in the 16th century, they brought their coinage with them—and, secondarily, the common name for the coins minted at Joachimsthal: Joachimsthaler
, or thaler
for short. For whatever reason, it was this German term that came to America, becoming the familiar word "dollar."
Before the The American Revolution
, it was common in multiple world currencies to physically slice a dollar (or equivalent) coin into eight bits
worth 12.5 cents each. The highly popular Spanish Milled Dollar, as already mentioned, was worth eight Spanish Reals — which was why pirates called them "pieces of eight". Slicing it into 8 pieces produced 8 bits worth one Real apiece. The "bit" denomination has survived today primarily in colloquialism: a Shave And A Haircut
cost a quarter of a dollar, or "two bits", as advertised by barbershop quartets. This convention of dividing a dollar into 8 pieces also persisted in the Stock Market all the way through the 1980s; if you watch an older movie with the Stock Market in it, you'll see stock prices like "11 5/8" dollars per share.
Prior to the mid-19th century, there were also silver five-cent "half dimes" — among the smallest and thinnest coins ever minted in the U.S. — and half cent coins. One mill tokens were unofficially made by some private firms, but never officially minted by the Federal government. In the mid-19th century, the U.S. experimented unsuccessfully with 20 and 2 cent coins. The 20 cent coin failed to catch on because it was so easy to confuse with a quarter (much like the Susan B. Anthony dollar was in 1979); and although the 2 cent coin eventually faded into obscurity, it has the distinction of being the very first
piece of U.S. currency — coin, paper, or otherwise — to bear the words "In God we trust." (This last was partly a result of the increased religious fervor felt during the The American Civil War
; the 2 cent piece was first minted in 1864.)
Until 1933, the U.S. also minted gold
currency, based around a gold-only denomination called the Eagle. Just as a Dime is an official currency unit worth 1/10 of a dollar, so an Eagle was an official currency unit worth 10 dollars. There were quarter eagle coins (worth $2.50 each), half eagles ($5), eagles ($10), and even double eagles ($20)note
. There were also gold $1 coins; during the The American Civil War
, the gold dollar was actually more popular than the silver dollar. With the coming of The Great Depression
, though, private ownership of gold in any form other than jewelry was outlawed. Gold coins were systematically removed from circulation and melted down; only those kept by private collectors survived. Today, the U.S. mint produces a series of bullion coins called American Eagles in their honor.
Paper money, called “bills” in the U.S., start at the dollar. One-dollar coins exist, but the paper one-dollar bill is far more popular. The next denomination up is the little-used $2 bill, which can sometimes lead to confusion as the younger generation does not always recognize it as legal tender. Next are the $5 and $10 bills. The $20 bill is probably the most commonly used in basic transactions, being the standard bill for ATM bank withdrawals, and is also known as a “yuppie food stamp.” Next up are the $50 and $100 bills. They're easy to misplace, what with being a thin strip of cottony paper, so don't! Unlike some other countries, American bills are all the same size and until recently all the same color (Black on white on the front. Green on white on the back. Hence greenbacks) In recent years redesigns have made some bills slightly more colorful as part of anti-counterfeiting measures, though still nowhere as colorful as Euro (or Canadian) bills.note
With the exception of the $10 and $100 dollar bill, all the US bills depict presidents of the United States, and the term "Dead Presidents" is a common colloquialism for money.
There were also 3¢, 5¢, 10¢, 15¢, 25¢, 50¢, $500, $1,000, $5,000, and $10,000 bills in circulation at one time, but they are no longer used and essentially never seen outside of collections - a famous (though sadly no longer existing) collection was a set of $10,000 bills on display at a Las Vegas casino to visually depict exactly what one million dollars looked like. $100,000 bills were used to settle accounts between banks, but were never released outside the banking system.
Through most of U.S. history, there were four types of bills issued by the US government - Silver Certificates
, Gold Certificates
, United States Notes
, and Federal Reserve Notes
The first two were specie-backed currency, meaning that their value was backed by an equivalent amount of the specific precious metal in their name. Because of the large number of gold certificates in circulation in 1933, there was a fear that a national panic would result in everybody trying to redeem their gold certificates at the same time, bankrupting the U.S. gold reserves; it was for this reason that private ownership of non-jewelry gold was outlawed. That law was not lifted until the 1960s.
United States Notes, and Federal Reserve Notes before 1963, were redeemable in “lawful money,” which was never defined by Congress; the only difference between these two types of paper money was that one was issued directly by the U.S. Treasury and was severely limited in the amount issued, and the other was issued by the Federal Reserve, the United State's decentralized central bank. Additionally, there were National Bank Notes
, bills issued by federally chartered banks that were backed by bonds deposited with the Treasury. After 1929, when US bills were shrunk to their current size and designs standardized for all five types, the color of the Treasury seal on the face could identify the type; gold certificates had yellow seals, silver certificates blue, US Notes red, Federal Reserve notes green and National Bank Notes brown.
Modern Federal Reserve Notes, which have been the only sort of paper money issued by the US Government since 1963, are fiat
currency - their value is not backed by any hard resource, but by the "full faith and credit" of the U.S. Government. In other words: it's partially trust (that the United States won't disappear tomorrow and the US government will be able to pay back its debts) and fear (because if you refuse to accept Federal Reserve Notes, someone can sue you and order you to—this is what "legal tender" means).note
"Dollars" and "cents" are usually not spelled out, so here are the relevant abbreviations (and symbols):
- $: Dollars. Appears before the number. Canada, which lies to the north of the U.S., also has a unit of currency called the dollar that's abbreviated by placing a $ before the number, except in Quebec.
- Confusingly, $ is also the abbreviation for Pesos in Mexico, which borders the U.S. to the south.
- Doubly confusing, some areas that operate with the US dollar (such as Puerto Rico or the Virgin Islands) may refer to a dollar as a "peso".
- ¢: Cents. Appears after the number. Used instead of, not in addition to, the dollar sign, and only if an integer number of cents are specified (rather than a decimal value of dollars). Almost never used these days, as (thanks to inflation) most goods worth buying cost more than a dollar. Even as early as the 1960s, when computer character sets were becoming standardized, neither the ASCII nor the EBCDIC character set contained a cents sign (American computer keyboards replaced it with the caret, i.e, ^). Windows allows you to access it (relatively) quickly by holding down ALT and typing "0162" on the number pad.
- Prices in dollars and cents are written with a decimal point; e.g., $4.35 means 4 dollars and 35 cents. A zero at the end of the decimal is never dropped, so 4 dollars and 50 cents would be written not as $4.5, as though it were a proper fraction, but always as $4.50.
A dollar is sometimes called a "buck," in the same way a British pound sterling is called a "quid." It got this slang name because, when the dollar was formally introduced in 1792, it was worth about as much as a deerskin, which were a kind of unofficial currency out in the wilderness.
