United States dollar-data source wikipedia

The U.S. dollar uses the decimal system, consisting of 100 equal cents (symbol ¢). In another division, there are 1,000 mills or ten dimes to a dollar, or 4 quarters to a dollar; additionally, the term eagle was used in the Coinage Act of 1792 for the denomination of ten dollars, and subsequently was used in naming gold coins. In the second half of the 19th century there were occasional discussions of creating a $50 gold coin, which was referred to as a "Half Union," thus implying a denomination of 1 Union = $100. However, only cents are in everyday use as divisions of the dollar; "dime" is used solely as the name of the coin with the value of 10¢, while "eagle" and "mill" are largely unknown to the general public, though mills are sometimes used in matters of tax levies and gasoline prices. When currently issued in circulating form, denominations equal to or less than a dollar are emitted as U.S. coins while denominations equal to or greater than a dollar are emitted as Federal Reserve notes (with the exception of gold, silver and platinum coins valued up to $100 as legal tender, but worth far more as bullion). (Both one-dollar coins and notes are produced today, although the note form is significantly more common.) In the past, paper money was occasionally issued in denominations less than a dollar (fractional currency) and gold coins were issued for circulation up to the value of $20 (known as the "double eagle", discontinued in the 1930s).

U.S. coins are produced by the United States Mint. U.S. dollar banknotes are printed by the Bureau of Engraving and Printing, and, since 1914, have been issued by the Federal Reserve. The "large-sized notes" issued before 1928 measured 7.42 inches (188 mm) by 3.125 inches (79.4 mm); small-sized notes, introduced that year, measure 6.14 inches (156 mm) by 2.61 inches (66 mm) by 0.0043 inches (0.11 mm).

[edit] Etymology

The name Thaler (from German thal, or nowadays usually Tal, "valley", cognate with "dale" in English) came from the German coin Guldengroschen ("great guilder", being of silver but equal in value to a gold guilder), minted from the silver from a rich mine at Joachimsthal (St. Joachim's Valley, now Jáchymov) in Bohemia (then part of the Holy Roman Empire, now part of the Czech Republic).

The colloquialism buck (much like the British term "quid") is often used to refer to dollars of various nations, including the U.S. dollar. This term, dating to the 18th century, may have originated with the colonial fur trade. Greenback is another nickname originally applied specifically to the 19th century Demand Note dollars created by Abraham Lincoln to finance the costs of the Civil War for the North. The original note was printed in black and green on the back side. It is still used to refer to the U.S. dollar (but not to the dollars of other countries).

Grand, sometimes shortened to simply G, is a common term for the amount of $1,000. The suffix k (from "kilo-") is also commonly used to denote this amount (such as "$10k" to mean $10,000). Banknotes' nicknames are usually the same as their values (such as five, twenty, etc.) The $5 bill has been referred to as a "fin" or a "fiver" or a "five-spot;" the $10 bill as a "sawbuck," a "ten-spot," or a "Hamilton"; the $20 bill as a "double sawbuck," a "twomp," a "twenty-banger," or a "Jackson"; the $1 bill is sometimes called a "single," the $2 bill a "deuce" or a "Tom," and the $100 bill is nicknamed the hunsky, a "Benjamin," "Benjie," or "Frank" (after Benjamin Franklin, who is pictured on the note), C-note (C being the Roman numeral for 100), Century Note, or "bill" ("two bills" being $200, etc.). The dollar has also been referred to as a "bone" or "bones" (i.e. twenty bones is equal to $20) or a "bean" for slang on the East Coast (primarily in New York). Occasionally these will be referred to as "dead presidents," although neither Hamilton ($10) nor Franklin ($100) was President. $1000 notes are occasionally referred to as 'large' in banking ("twenty large" being $20,000, etc.). The newer designs are sometimes referred to as "Bigface" bills.

In Panama, the translation of buck is palo (lit. stick); a nickname for the balboa. For example: "Esto vale 20 palos" ("This is worth 20 bucks"). In Puerto Rico (as well as by Puerto Ricans living in the continental U.S.), the dollar may be referred to as a peso. In French-speaking areas of Louisiana, the dollar is referred to as a piastre which is pronounced "pee-as", and cents by the French holdhover of sous, pronounced "soo." In Mexico, prices in dollars are referred in some places to as "en americano" ("in American"): one would ask "¿Cuánto cuesta en americano?" ("How much does it cost 'in American'?") and would receive the U.S. dollar price in the Spanish language. (In Mexico, peso is used primarily for the Mexican peso.) In Peru, a nickname for the U.S. dollar is coco, which is a pet name for Jorge (George in Spanish), an alleged reference to the portrait of George Washington on the $1 note.

[edit] Dollar sign
Main article: Dollar sign

The symbol $, usually written before the numerical amount, is used for the U.S. dollar (as well as for many other currencies). The sign's ultimate origins are not certain, though it is widely accepted that it comes from the symbol for the New Spanish (Mexican) peso which in turn comes from the Spanish Coat of arms. This takes the form of two vertical bars and a swinging cloth band in the shape of an "S".

The first dollar coins issued by the United States Mint were of the same size and composition as the Spanish dollar and even after the American Revolutionary War the Spanish and U.S. silver dollars circulated side by side in the United States. The coinage of various English colonies also circulated. The lion dollar was popular in the Dutch New Netherland Colony (New York), but the lion dollar also circulated throughout the English colonies during the seventeenth and early eighteenth centuries. Examples circulating in the colonies were usually worn so that the design was not fully distinguishable, thus they were sometimes referred to as "dog dollars".[5]

The U.S. dollar was created and defined by the Coinage Act of 1792. It specified a "dollar" to be between 371 and 416 grains (27.0 g) of silver (depending on purity) and an 'eagle" to be between 247 and 270 grains (17 g) of gold (again depending on purity). It set the value of an eagle at 10 dollars, and the dollar at 1/10th eagle. It called for 90% silver alloy coins in denominations of 1, 1/2, 1/4, 1/10, and 1/20; it called for 90% gold alloy coins in denominations of 1, 1/2, 1/4, and 1/10.

The value of gold or silver contained in the dollar was then converted into relative value in the economy for the buying and selling of goods. This allowed the value of things to remain fairly constant over time, except for the influx and outflux of gold and silver in the nation's economy.
