Collector coins

        The United States Mint produces Proof Sets specifically for collectors and speculators. Silver Proofs tend to be the standard designs but with the dime, quarter, half dollar, and in some cases the dollar having silver content. Another type of proof set is the Presidential Dollar Proof Set where four special $1 coins are minted each year featuring a president.

2007 had George Washington, John Adams, Thomas Jefferson, and James Madison
2008 had James Monroe, John Quincy Adams, Andrew Jackson, and Martin Van Buren
2009 had William Henry Harrison, John Tyler, James K. Polk, and Zachary Taylor
2010 had Millard Fillmore, Franklin Pierce, James Buchanan, and Abraham Lincoln
2011 had Andrew Johnson, Ulysses S. Grant, Rutherford B. Hayes, and James A. Garfield
2012 had Chester Arthur, Grover Cleveland, Benjamin Harrison, and Grover Cleveland (2nd term)
2013 will have William McKinley, Theodore Roosevelt, William Howard Taft and Woodrow Wilson

Dollar coins

Flowing Hair DollarThe first United States dollar was minted in 1794. Known as the Flowing Hair Dollar, it contained 416 grains of "standard silver" (89.25% silver and 10.75% copper), as specified by Section 13 of the Coinage Act of 1792. It was designated by Section 9 of that Act as having "the value of a Spanish milled dollar".

Dollar coins have not been very popular in the United States.Silver dollars were minted intermittently from 1794 through 1935; a copper-nickel dollar of the same large size, featuring President Dwight D. Eisenhower, was minted from 1971 through 1978. Gold dollars were also minted in the 19th century. The Susan B. Anthony dollar coin was introduced in 1979; these proved to be unpopular because they were often mistaken for quarters, due to their nearly equal size, their milled edge, and their similar color. Minting of these dollars for circulation was suspended in 1980 (collectors' pieces were struck in 1981), but, as with all past U.S. coins, they remain legal tender. As the number of Anthony dollars held by the Federal Reserve and dispensed primarily to make change in postal and transit vending machines had been virtually exhausted, additional Anthony dollars were struck in 1999. In 2000, a new $1 coin, featuring Sacagawea, (the Sacagawea dollar) was introduced, which corrected some of the mistakes of the Anthony dollar by having a smooth edge and a gold color, without requiring changes to vending machines that accept the Anthony dollar. However, this new coin has failed to achieve the popularity of the still-existing $1 bill and is rarely used in daily transactions. The failure to simultaneously withdraw the dollar bill and weak publicity efforts have been cited by coin proponents as primary reasons for the failure of the dollar coin to gain popular support.

In February 2007, the U.S. Mint, under the Presidential $1 Coin Act of 2005, introduced a new $1 U.S. Presidential dollar coin. Based on the success of the "50 State Quarters" series, the new coin features a sequence of presidents in order of their inaugurations, starting with George Washington, on the obverse side. The reverse side features the Statue of Liberty. To allow for larger, more detailed portraits, the traditional inscriptions of "E Pluribus Unum", "In God We Trust", the year of minting or issuance, and the mint mark will be inscribed on the edge of the coin instead of the face. This feature, similar to the edge inscriptions seen on the British £1 coin, is not usually associated with U.S. coin designs. The inscription "Liberty" has been eliminated, with the Statue of Liberty serving as a sufficient replacement. In addition, due to the nature of U.S. coins, this will be the first time there will be circulating U.S. coins of different denominations with the same president featured on the obverse (heads) side (Lincoln/penny, Jefferson/nickel, Franklin D. Roosevelt/dime, Washington/quarter and Kennedy/half dollar/dollar). Another unusual fact about the new $1 coin is Grover Cleveland will have two coins with his portrait issued due to the fact he was the only U.S. President to be elected to two non-consecutive terms.

Early releases of the Washington coin included error coins shipped primarily from the Philadelphia mint to Florida and Tennessee banks. Highly sought after by collectors, and trading for as much as $850 each within a week of discovery, the error coins were identified by the absence of the edge impressions "E PLURIBUS UNUM IN GOD WE TRUST 2007 P". The mint of origin is generally accepted to be mostly Philadelphia, although identifying the source mint is impossible without opening a mint pack also containing marked units. Edge lettering is minted in both orientations with respect to "heads", some amateur collectors were initially duped into buying "upside down lettering error" coins. Some cynics also erroneously point out that the Federal Reserve makes more profit from dollar bills than dollar coins because they wear out in a few years, whereas coins are more permanent. The fallacy of this argument arises because new notes printed to replace worn out notes, which have been withdrawn from circulation bring in no net revenue to the government to offset the costs of printing new notes and destroying the old ones. As most vending machines are incapable of making change in banknotes, they commonly accept only $1 bills, though a few will give change in dollar coins.

Silver and gold standards

           From 1792, when the Mint Act was passed, the dollar was defined as 371.25 grains (24.056 g) of silver. Many historians erroneously assume gold was standardized at a fixed rate in parity with silver; however, there is no evidence of Congress making this law. This has to do with Alexander Hamilton's suggestion to Congress of a fixed 15:1 ratio of silver to gold, respectively. The gold coins that were minted however, were not given any denomination whatsoever and traded for a market value relative to the Congressional standard of the silver dollar. 1834 saw a shift in the gold standard to 23.2 grains (1.50 g), followed by a slight adjustment to 23.22 grains (1.505 g) in 1837 (16:1 ratio)
In 1862, paper money was issued without the backing of precious metals, due to the Civil War. Silver and gold coins continued to be issued and in 1878 the link between paper money and coins was reinstated. This disconnection from gold and silver backing also occurred during the War of 1812. The use of paper money not backed by precious metals had also occurred under the Articles of Confederation from 1777 to 1788. With no solid backing and being easily counterfeited, the continentals quickly lost their value, giving rise to the phrase "not worth a continental". This was a primary reason for the "No state shall... make any thing but gold and silver coin a tender in payment of debts" clause in article 1, section 10 of the United States Constitution.
The Gold Standard Act of 1900 abandoned the bimetallic standard and defined the dollar as 23.22 grains (1.505 g) of gold, equivalent to setting the price of 1 troy ounce of gold at $20.67. Silver coins continued to be issued for circulation until 1964, when all silver was removed from dimes and quarters, and the half dollar was reduced to 40% silver. Silver half dollars were last issued for circulation in 1970. Gold coins were confiscated by Executive Order 6102 issued in 1933 by Franklin Roosevelt. The gold standard was changed to 13.71 grains (0.888 g), equivalent to setting the price of 1 troy ounce of gold at $35. This standard persisted until 1968.
Between 1968 and 1975, a variety of pegs to gold were put in place, eventually culminating in a sudden end, on August 15, 1971 to the convertibility of dollars to gold later dubbed the Nixon Shock. The last peg was $42.22 per ounce before the U.S. dollar was let to freely float on currency markets.
According to the Bureau of Engraving and Printing, the largest note it ever printed was the $100,000 Gold Certificate, Series 1934. These notes were printed from December 18, 1934 through January 9, 1935, and were issued by the Treasurer of the United States to Federal Reserve Banks only against an equal amount of gold bullion held by the Treasury. These notes were used for transactions between Federal Reserve Banks and were not circulated among the general public.

Origins of the dollar sign

           The sign is first attested in business correspondence in the 1770s as a scribal abbreviation "p^s", referring to the Spanish American peso, that is, the "Spanish dollar" as it was known in British North America. These late eighteenth- and early nineteenth-century manuscripts show that the s gradually came to be written over the p developing a close equivalent to the "$" mark, and this new symbol was retained to refer to the American dollar as well, once this currency was adopted in 1785 by the United States.

An alternative theory states that the dollar sign ($) is directly borrowed from the sign used to represent the Spanish peso, which is in fact a "$", and is said to come from a representation of one of the Pillars of Hercules with a motto-ribbon as depicted in the Spanish Coat-of-Arms.

Etymology

            On 15 January 1520, Bohemia began minting coins known as Jachymovsky Tolar, named for Jáchymov, where the silver was mined.(In German, thal or tal refers to a valley or dale.) German name "Joachimsthaler" was later shortened in common usage to taler or thaler (same pronunciation) and this shortened word eventually found its way into other languages: Czech tolar, Hungarian tallér, Danish and Norwegian (rigs) daler, Swedish (riks) daler, Icelandic dalur, Dutch (rijks) daalder or daler, Ethiopian ታላሪ ("talari"), Italiantallero, Flemish daelder, Polish Talar, Persian Dare, as well as - via Dutch - into English as dollar.

The coins minted at Jáchymov soon lent their name to other coins of similar size and weight from other places. One such example, was a Dutch coin depicting a lion, hence its Dutch name leeuwendaler (English lion daler). The Dutch Republic produced these coins to accommodate its booming international trade.

The leeuwendaler or leeuwendaalder circulated throughout the Middle East and was imitated in several German and Italian cities. Carried by Dutch traders, this coin was also popular in the Dutch East Indies and in the Dutch New Netherland Colony (New York), and circulated throughout the Thirteen Colonies during the 17th and early 18th centuries and was popularly known as lion (or lyon) dollar - and is in fact the origin of the name Dollar. The modern American-English pronunciation of dollar is still remarkably close to the 17th century Dutch pronunciation of daler. Some well-worn examples circulating in the Colonies were known as "dog dollars".

By analogy with this lion dollar, Spanish pesos - having the same weight and shape - came to be known as Spanish dollars. By the mid-18th century, the lion dollar had been replaced by Spanish dollar, the famous "piece of eight", which were distributed widely in the Spanish colonies in the New World and in the Philippines.

History

The word dollar comes from the name "Tolar" given to coins first minted in 1520 from locally mined silver in Jáchymov inBohemia. The town now lies within the borders of the Czech Republic.

Later on, dollar - the English transliteration of Tolar - was applied to similar coins, not only ones minted in Bohemia or in central Europe, but also the Spanish peso and the Portuguese eight-real piece. Both of these large silver coins were practically identical in weight and fineness. Today the phrase "pieces of eight" is known from tales of pirates in the Caribbean.

Doller

•         The dollar (often represented by the dollar sign $) is the name of the official currency or a banknote of many countries, territories and dependencies, including Australia, Belize, Canada, Hong Kong, New Zealand, Singapore, Taiwan, Bruneiand the United States. Generally, one dollar is equal to 100 cents.

  
  

United States dollar

The United States dollar (sign: $; code: USD; also abbreviated US$), also referred to as the U.S. dollar or American dollar, is the official currency of the United States of America and its overseas territories. It is divided into 100 smaller units called cents.

The U.S. dollar is the currency most used in international transactions and is one of the world's dominant reserve currencies.[15] Several countries use it as their official currency, and in many others it is the de facto currency.[16] It is also used as the sole currency in two British Overseas Territories, the British Virgin Islands and the Turks and Caicos islands.
