Coin Set
A coin set, or mint set, is a collection of Uncirculated or Proof coins, released by a mint. Such sets are usually released annually and often called a year set. They include sets of all the circulating coins of that year, as well as sets of commemorative coins. The Royal Mint, Royal Australian Mint, Royal Canadian Mint, United States Mint and others mints all release sets of proof and uncirculated coins each year. Sometimes the coins for annual sets are struck in a special way. For example, the Danmarks Nationalbank issues a coin set each year with coins that are "much more clearly embossed than the ordinary coins in circulation." Early coin sets were issued in paper of cardboard folders which often led to toning, due to the sulphur content of the card.

2007 United States Mint Annual Uncirculated Dollar Coin Set
7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arabs developed the digit f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uncirculated Coin
The term uncirculated coin can refer to three things: * A coin that is released to the public but not intended for general circulation (i.e. not used as money although it is still legal tender) but is available through a mint or through a local coin dealer. * A coin that has been graded as 60+ on the Sheldon or European grading systems. * The process by which a coin is made. The US Mint uses this definition for the coins in the uncirculated coin set that it sells. For these coins, adjustments are made to the minting process which result in a more proof-like finish. These include using a higher force during coining, the use of fresh dies, and special cleaning. See also *Proof coinage Proof coinage refers to special early samples of a coin issue, historically made for checking the dies (as in demonstrating that something is true) and for archival purposes. Nowadays proofs are often struck in greater numbers specially for co ... References * {{DEFAULTSORT:Unc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proof Coinage
Proof coinage refers to special early samples of a coin issue, historically made for checking the dies (as in demonstrating that something is true) and for archival purposes. Nowadays proofs are often struck in greater numbers specially for coin collectors (numismatists). Nearly all countries have issued proof coinage. Preparation of a proof striking usually involved polishing of the dies. They can usually be distinguished from normal circulation coins by their sharper rims and design, as well as much smoother "fields" – the blank areas not part of the coin's design. The dies for making modern proof coins are often treated with chemicals to make certain parts of the design take on a frosted appearance, with the polished fields taking on a mirror finish. Several other methods have been used in the past to achieve this effect, including sand blasting the dies, and matte proofs. Proof coins of the early 19th century even appear to be scratched, but it was part of the production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mint (coin)
A mint is an industrial facility which manufactures coins that can be used as currency. The history of mints correlates closely with the history of coins. In the beginning, hammered coinage or cast coinage were the chief means of coin minting, with resulting production runs numbering as little as the hundreds or thousands. In modern mints, coin dies are manufactured in large numbers and planchets are made into milled coins by the billions. With the mass production of currency, the production cost is weighed when minting coins. For example, it costs the United States Mint much less than 25 cents to make a quarter (a 25 cent coin), and the difference in production cost and face value (called seigniorage) helps fund the minting body. Conversely, a U.S. penny ($0.01) cost $0.015 to make in 2016. History The first minted coins The earliest metallic money did not consist of coins, but of unminted metal in the form of rings and other ornaments or of weapons, which were used for th ...

Commemorative Coin
Commemorative coins are coins issued to commemorate some particular event or issue with a distinct design with reference to the occasion on which they were issued. Many coins of this category serve as collectors items only, although some countries also issue commemorative coins for regular circulation. Subcategories Commemorative coins can be seen as being of one of three types: *'' Regular issue coinage'' are the normal coins intended to be used in commerce every day and are typically issued with the same design for several years, e.g. euro coins. *''Circulating commemoratives'' are intended to be used for commerce, but the design will only be issued for a limited time to commemorate an event, anniversary, person or location, among other items. Examples include the €2 commemorative coins and U.S. 50 State Quarters. *''Non-circulating legal tender (NCLT)'' are coins which are legal tender, and thus can in theory be used to purchase goods or services, but are not intended to b ...

Royal Mint
The Royal Mint is the United Kingdom's oldest company and the official maker of British coins. Operating under the legal name The Royal Mint Limited, it is a limited company that is wholly owned by His Majesty's Treasury and is under an exclusive contract to supply the nation's coinage. As well as minting circulating coins for the UK and international markets, The Royal Mint is a leading provider of precious metal products. The Royal Mint was historically part of a series of mints that became centralised to produce coins for the Kingdom of England, all of Great Britain, the United Kingdom, and nations across the Commonwealth. The Royal Mint operated within the Tower of London for several hundred 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-acre (15 ha) plant in Llantrisant, Glamorgan, Wales, where it has remained sin ...

Royal Australian Mint
The Royal Australian Mint is the sole producer of all of Australia's circulating coins and is a Commonwealth Government entity operating within the portfolio of the Treasury. The Mint is situated in the Australian federal capital city of Canberra, in Denison St, in the suburb of Deakin. The Mint was opened in 1965 by Prince Philip, Duke of Edinburgh. Before the opening of the Australian Mint, Australian coins were struck at the Sydney Mint, Melbourne Mint and Perth Mint. As such, the Royal Australian Mint was the first mint in Australia to be independent of the British Royal Mint, in the United Kingdom, which was a British government entity. (Of the three older Australian mints, only Perth Mint has remained; it was a subsidiary of the UK Royal Mint until 1970.) Foundations and history Planning for the mint started in 1959 when it was proposed to move the Melbourne branch of the Royal Mint to Canberra, with a large site in the Canberra suburb of Deakin chosen.

United States Mint
The United States Mint is a bureau of the Department of the Treasury responsible for producing coinage for the United States to conduct its trade and commerce, as well as controlling the movement of bullion. It does not produce paper money; that responsibility belongs to the Bureau of Engraving and Printing. The first United States Mint was created in Philadelphia in 1792, and soon joined by other centers, whose coins were identified by their own mint marks. There are currently four active coin-producing mints: Philadelphia, Denver, San Francisco, and West Point. History The Massachusetts Bay Colony established a mint in Boston in 1652. John Hull was Treasurer and mintmaster; Hull's partner at the "Hull Mint" was Robert Sanderson. The historical marker reads: The first authorization for the establishment of a mint in the United States was in a resolution of the Congress of the Confederation of February 21, 1782, and the first general-circulation coin of the United States ...

Danmarks Nationalbank
Danmarks Nationalbank (in Danish often simply ''Nationalbanken'') is the central bank of the Kingdom of Denmark. It is a non-eurozone member of the European System of Central Banks ( ESCB). Since its establishment in 1818, the objective of the Nationalbank as an independent and credible institution is to issue the Danish currency, the krone, and ensure its stability. The Board of Governors holds full responsibility for the monetary policy. The building which houses the bank's headquarters was designed by the renowned architect Arne Jacobsen, in collaboration with Hans Dissing and Otto Weitling. After Jacobsen's death, his office, renamed Dissing+Weitling, has brought the construction to completion. Danmarks Nationalbank undertakes all functions related to the management of the Danish central-government debt. The division of responsibility is set out in an agreement between the Ministry of Finance of Denmark and Danmarks Nationalbank. Danish and Faroese banknotes were previou ...

Toning (coin)
Toning on a coin is the change of colour brought about through oxidization, which forms a thin layer of tarnish on the metal's surface. Coin toning can vary in aesthetics, and thus can alternately add or detract from a coin's value. Coins with unusual toning colours or patterns tend to be valued by coin collectors. Toning is most common on silver coins, but can be found on coins minted from other metals and alloys, including gold, copper and cupronickel. Types of toning Different colors and patterns of toning can have varying effects on a coin's grade and value. For example, brown spotty toning could decrease a coin's value, while colorful rainbow toning could increase it. Similarly, toning can raise or lower a coin's grade by several points, as grading is based on factors including eye appeal and not just wear. Depending on the environment in which the toning took place, toned coins can come in many different colors and color combinations. Toning patterns may cover an entire co ...

Sulphur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
