U.S. Coins
Coins of the United States dollar – aside from those of the earlier Continental currency – were first minted in 1792. New coins have been produced annually and they comprise a significant aspect of the United States currency system. Circulating coins exist in denominations of 1¢ (i.e. 1 cent or $0.01), 5¢, 10¢, 25¢, 50¢, and $1.00. Also minted are bullion, including gold, silver and platinum, and commemorative coins. All of these are produced by the United States Mint. The coins are then sold to Federal Reserve Banks which in turn put coins into circulation and withdraw them as demanded by the United States economy. Current coinage Four mints currently operate in the United States, producing billions of coins each year. The main mint is the Philadelphia Mint, which produces circulating coinage, mint sets and commemorative coins. The Denver Mint also produces circulating coinage, mint sets and commemoratives. The San Francisco Mint produces regular and silver proof coi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Dollar
The United States dollar (Currency symbol, symbol: Dollar sign, $; ISO 4217, currency code: USD) is the official currency of the United States and International use of the U.S. dollar, several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish dollar, Spanish silver dollar, divided it into 100 cent (currency), cents, and authorized the Mint (facility), minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The U.S. dollar was originally defined under a bimetallism, bimetallic standard of (0.7734375 troy ounces) fine silver or, from Coinage Act of 1834, 1834, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important intern ... [...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 die (manufacturing), dies (as in demonstrating that something is true) and for archival purposes. In modern times, proofs are often struck in greater numbers, especially for coin collecting, 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 b ...

Zinc
Zinc is a chemical element; it has symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It is the second most abundant trace metal in humans after iron, an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Penny (United States Coin)
The penny, officially known as the cent, is a coin in the United States representing one-hundredth of a dollar. It has been the lowest face-value physical unit of U.S. currency since the abolition of the half-cent in 1857 (the abstract mill, which has never been minted, equal to a tenth of a cent, continues to see limited use in the fields of taxation and finance). The U.S. Mint's official name for the coin is " cent" and the U.S. Treasury's official name is "one cent piece". The colloquial term ''penny'' derives from the British coin of the same name, which occupies a similar place in the British system. ''Pennies'' is the plural form (not to be confused with ''pence'', which refers to the unit of currency). The first U.S. cent was produced in 1787, and the cent has been issued primarily as a copper or copper-plated coin throughout its history. In 1792, Congress established the US Mint, which began producing coins. In the same year, the Coinage Act of 1792 mand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obverse And Reverse
The obverse and reverse are the two flat faces of coins and some other two-sided objects, including paper money, flags, seals, medals, drawings, old master prints and other works of art, and printed fabrics. In this usage, ''obverse'' means the front face of the object and ''reverse'' means the back face. The obverse of a coin is commonly called ''heads'', because it often depicts the head of a prominent person, and the reverse ''tails''. In numismatics, the abbreviation ''obv.'' is used for ''obverse'',David Sear. ''Greek Imperial Coins and Their Values.'' Spink Books, 1982. p. xxxv. while , )(Jonathan Edwards.

Dahlonega Mint
The Dahlonega Mint was a former Branch mint, branch of the United States Mint built during the Georgia Gold Rush to help the miners get their gold assayed and coining (mint), minted, without having to travel to the Philadelphia Mint. It was located at (34°31.8′N 83°59.2′W ) in Dahlonega, Lumpkin County, Georgia. Coins produced at the Dahlonega Mint bear the "D" mint mark. That mint mark is used today by the Denver Mint, which opened in 1906, over four decades after the Dahlonega Mint closed. All coins from the Dahlonega Mint are gold, in the $1, $2.50, $3, and $5 denominations, and bear dates in the range 1838–1861. Creation The Mint Act of 1835, established by the United States Congress on 3 March, established "one branch at the city of New Orleans for the coinage of gold and silver; one branch at the town of Charlotte, North Carolina, Charlotte...for the coinage of gold only; and one branch at or near Dahlonega, in Lumpkin County, in the state of Georgia, also for the co ...

Charlotte Mint
The Charlotte Mint was the first United States branch mint. It was located in Charlotte, North Carolina and specialized in gold coinage. History Following the first documented discovery of gold in the United States, the country's first gold mine was established in North Carolina at the Reed Gold Mine. As no mints existed in the Charlotte area, miners had to send their gold dust to Philadelphia to be melted and coined. The transportation process was difficult, slow, expensive, and dangerous; frustration with this system led to the creation of private gold coining operations in the Charlotte area. However, making gold into local money had its own inherent problems, such as accurate weighing and determining fineness. In the spring of 1831, North Carolina merchants and miners petitioned Congress for a branch mint in the Charlotte region to reduce the risk of transporting gold. They received no response until three years later when the United States Treasury began to investigate priv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Orleans Mint
The New Orleans Mint () operated in New Orleans, Louisiana, as a branch mint (facility), mint of the United States Mint from 1838 to 1861 and from 1879 to 1909. During its years of operation, it produced over 427 million gold and silver coins of nearly every United States coinage, American denomination, with a total face value of over United States dollar, US$ 307 million. It was closed during most of the American Civil War and Reconstruction Era, Reconstruction. After it was decommissioned as a mint, the building has served a variety of purposes, including as an assay office, a United States Coast Guard storage facility, and a fallout shelter. Since 1981 it has served as a branch of the Louisiana State Museum. Damaged by Hurricane Katrina in 2005, after over two years of repairs and renovations, the museum reopened in October 2007. Exhibits include instruments used by some of New Orleans' notable jazz musicians, photographs, and posters, now part of the New Orleans Jazz Mus ...

Carson City Mint
The Carson City Mint was a branch of the United States Mint in Carson City, Nevada. It primarily minted silver coins; however, it also minted gold coins, with a total face value in dollars nearly equal to that of its silver coins. The mint minted coins in 21 different years. The Carson City Mint was created in 1863 but was not put into operation until 1870. It ran until 1885, went on a hiatus, and resumed operations in 1889, after which it ran until 1893, when it closed permanently. It is now the Nevada State Museum, Carson City. History Built at the peak of the silver boom conveniently near a local silver mine, 50 issues of silver coins and 57 issues of gold coins minted here between 1870 and 1893 bore the "CC" mint mark. The mint was established in Carson City to facilitate minting of silver coins from silver in the Comstock Lode, much as the San Francisco Mint was established to facilitate minting gold coins from the gold of the California gold rush. From 1895 to 1933, the bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
