paragraph_text: The Royal Mint is a government - owned mint that produces coins for the United Kingdom. Operating under the name Royal Mint Ltd, the mint is a limited company that is wholly owned by Her Majesty's Treasury and is under an exclusive contract to supply all the nation's coinage. As well as minting circulating coins for use domestically and internationally, the mint also produces planchets, commemorative coins, various types of medals and precious metal bullion. The mint exports to an average of 60 countries a year, making up 70% of its total sales. Formed over 1,100 years ago, the mint was historically part of a series of mints that became centralised to produce coins for the Kingdom of England, all of Great Britain and eventually most of the British Empire. The original London mint from which the Royal Mint is the successor, was established in 886 AD and operated within the Tower of London for approximately 800 years before moving to what is now called Royal Mint Court where it remained until the 1960s. As Britain followed the rest of the world in decimalising its currency, the Mint moved from London to a new 38 acres (15 ha) plant in Llantrisant, Wales where it has remained since.

paragraph_text: The San Francisco Mint is a branch of the United States Mint and was opened in 1854 to serve the gold mines of the California Gold Rush. It quickly outgrew its first building and moved into a new one in 1874. This building, the Old United States Mint, also known affectionately as The Granite Lady, is one of the few that survived the great 1906 San Francisco earthquake. It served until 1937, when the present facility was opened.

paragraph_text: The dollar coin is a United States coin worth one United States dollar. It is the third largest American coin currently minted in terms of physical size, with a diameter of 1.043 inches (26.5 mm) and a thickness of. 079 inches (2 mm), coming second to the half dollar. Dollar coins have been minted in the United States in gold, silver, and base metal versions. Dollar coins were first minted in the United States in 1794. The term silver dollar is often used for any large white metal coin issued by the United States with a face value of one dollar, whether or not it contains some of that metal. While true gold dollars are no longer minted, the Sacagawea and Presidential dollars are sometimes referred to as golden dollars due to their color.

paragraph_text: The Coinage Act of 1792, passed on April 2, 1792, authorized the mintage of a "disme", one-tenth the silver weight and value of a dollar. The composition of the disme was set at 89.24% silver and 10.76% copper. In 1792, a limited number of dismes were minted but never circulated. Some of these were struck in copper, indicating that the 1792 dismes were in fact pattern coins. The first dimes minted for circulation did not appear until 1796, due to a lack of demand for the coin and production problems at the United States Mint.

paragraph_text: The question of whether the government should intervene or not in the regulation of the cyberspace is a very polemical one. Indeed, for as long as it has existed and by definition, the cyberspace is a virtual space free of any government intervention. Where everyone agree that an improvement on cybersecurity is more than vital, is the government the best actor to solve this issue? Many government officials and experts think that the government should step in and that there is a crucial need for regulation, mainly due to the failure of the private sector to solve efficiently the cybersecurity problem. R. Clarke said during a panel discussion at the RSA Security Conference in San Francisco, he believes that the "industry only responds when you threaten regulation. If industry doesn't respond (to the threat), you have to follow through." On the other hand, executives from the private sector agree that improvements are necessary, but think that the government intervention would affect their ability to innovate efficiently.

paragraph_text: The Australian Threepence is a small silver coin used in the Commonwealth of Australia prior to decimalisation. It was minted from 1910 until 1964, excluding 1913, 1929–1933 inclusive, 1937, 1945 and 1946. After decimalisation on 14 February 1966, the coin was equivalent to 2½¢, but was rapidly withdrawn from circulation.

paragraph_text: At about the same time, coins and mints appeared independently in China and spread to Korea and Japan. The manufacture of coins in the Roman Empire, dating from about the 4th century BC, significantly influenced later development of coin minting in Europe.

paragraph_text: RSA SecurID, formerly referred to as SecurID, is a mechanism developed by Security Dynamics (later RSA Security and now RSA, The Security Division of EMC) for performing two - factor authentication for a user to a network resource.

paragraph_text: Though not commonly used today, half dollar coins have a long history of heavy use alongside other denominations of coinage, but have faded out of general circulation for many reasons. They were produced in fairly large quantities until the year 2002, when the U.S. Mint ceased production of the coin for general circulation. As a result of its decreasing usage, a large amount of pre-2002 half dollars remain in Federal Reserve vaults, prompting the change in production. Presently, collector half dollars can be ordered straight from the U.S. Mint, and pre-2002 circulation half dollars may be ordered through most U.S. banks.

paragraph_text: The Indian 10 - rupee coin (₹10) is a denomination of the Indian rupee. The ₹10 coin is the highest - denomination coin minted in India since its introduction in 2005. The present ₹10 coin in circulation is from the 2011 design. However, the previous ₹10 coins minted before 2011 are also legal tender in India. All ₹10 coins containing the rupee sign or without the rupee sign are legal tender, as stated by the Reserve Bank of India.

paragraph_text: All releases from 1936 to 1972 included the cent, nickel, dime, quarter, and half dollar from that year. The first proof sets through 1964 were minted at the Philadelphia Mint. There were two official releases in 1942: one regular five coin set and a set including a silver wartime nickel. United States currency was debased beginning in 1965, but the sets continued under the name United States Mint Proof Set. Production was moved to the San Francisco branch in 1968, and all subsequent issues bear coins with an ``S ''mint mark. In 1973, the Eisenhower dollar was added to the collection. Sets from 1975 will have a dual - date 1776 - 1976 quarter, half - dollar, and dollar as none of those coins were ever produced with a 1975 date. The Susan B. Anthony dollar replaced the Eisenhower in 1979. The 1981 mint sets were the only method of obtaining a Susan B. from that year, though many have slipped into circulation. With the cease in minting of dollar coins, the regular issue Proof Set for 1982 included a brass token. From 1983 until 1998, the annual United States Proof set resumed to only issuing the penny, nickel, dime, quarter, and half - dollar.

paragraph_text: 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, Kennedy/half dollar, and Eisenhower/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.

paragraph_text: The dollar was first based on the value and look of the Spanish dollar, used widely in Spanish America from the 16th to the 19th centuries. The first dollar coins issued by the United States Mint (founded 1792) were similar in size and composition to the Spanish dollar, minted in Mexico and Peru. The Spanish, U.S. silver dollars, and later, Mexican silver pesos circulated side by side in the United States, and the Spanish dollar and Mexican peso remained legal tender until the Coinage Act of 1857. 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 17th century and early 18th century. 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".

It is the second largest American coin currently minted for circulation in terms of physical size, with a diameter of 1.043 inches (26.5 mm) and a thickness of. 079 inches (2 mm), coming second to the half dollar. Dollar coins have been minted in the United States in gold, silver, and base metal versions. Dollar coins were first minted in the United States in 1794.

paragraph_text: The United States Bicentennial coinage was a set of circulating commemorative coins, consisting of a quarter, half dollar and dollar struck by the United States Mint in 1975 and 1976. Regardless of when struck, each coin bears the double date 1776 -- 1976 on the normal obverses for the Washington quarter, Kennedy half dollar and Eisenhower dollar. No coins dated 1975 of any of the three denominations were minted.

paragraph_text: The first issue (1966) was produced by three mints: 146.5 million were minted at the Royal Australian Mint in Canberra, with 239 million at the Melbourne Mint and 26.6 million at the Perth Mint. With the exception of 1966 and 1981, all other one - cent coins have been produced at the Canberra mint. In 1981, 40.3 million were struck at the British Royal Mint in Llantrisant, Wales, as well as 183.6 million in Canberra. The only year when it was not minted during its years in general circulation was 1986. It was last minted in 1990.

paragraph_text: The sixpence (6d; / ˈsɪkspəns /), sometimes known as a tanner or sixpenny bit, is a coin that was worth one - fortieth of a pound sterling, or six pence. It was first minted in the reign of Edward VI and circulated until 1980. Following decimalisation in 1971 it had a value of 2 1 / 2 new pence. The coin was made from silver from its introduction in 1551 to 1947, and thereafter in cupronickel.

paragraph_text: In 2007, the United States Mint began releasing a set of half-ounce $10 gold coins under the First Spouse Program with engravings of portraits of the First Ladies on the obverse. When a President served without a spouse, a gold coin was issued that bears an obverse image emblematic of Liberty as depicted on a circulating coin of that era and a reverse image emblematic of themes of that President's life. This is true for the coins for Thomas Jefferson, Andrew Jackson, Martin Van Buren, and James Buchanan's First Ladies, but not the coin for Chester A. Arthur's First Lady, which instead depicts suffragette Alice Paul.

paragraph_text: 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.

paragraph_text: The ten pence coin was originally minted from cupro - nickel (75% Cu, 25% Ni), but since 2012 it has been minted in nickel - plated steel due to the increasing price of metal. From January 2013 the Royal Mint began a programme to gradually remove the previous cupro - nickel coins from circulation with replacement by the nickel - plated steel versions.
