18 Carat
The fineness of a precious metal object (coin, bar, jewelry, etc.) represents the weight of ''fine metal'' therein, in proportion to the total weight which includes alloying base metals and any impurities. Alloy metals are added to increase hardness and durability of coins and jewelry, alter colors, decrease the cost per weight, or avoid the cost of high-purity refinement. For example, copper is added to the precious metal silver to make a more durable alloy for use in coins, housewares and jewelry. Coin silver, which was used for making silver coins in the past, contains 90% silver and 10% copper, by mass. Sterling silver contains 92.5% silver and 7.5% of other metals, usually copper, by mass. Various ways of expressing fineness have been used and two remain in common use: ''millesimal fineness'' expressed in units of parts per 1,000 and '' karats'' or ''carats'' used only for gold. Karats measure the parts per 24, so that 18 karat = = 75% and 24 karat gold is considered 100% go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precious Metal
Precious metals are rare, naturally occurring metallic chemical elements of high economic value. Chemically, the precious metals tend to be less reactive than most elements (see noble metal). They are usually ductile and have a high lustre. Historically, precious metals were important as currency but are now regarded mainly as investment and industrial raw materials. Gold, silver, platinum, and palladium each have an ISO 4217 currency code. The best known precious metals are the coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded. The demand for precious metals is driven not only by their practical use but also by their role as investments and a store of value. Historically, precious metals have commanded much hi ...

Hallmark
A hallmark is an official mark or series of marks struck on items made of metal, mostly to certify the content of noble metals—such as platinum, gold, silver and in some nations, palladium. In a more general sense, the term '' hallmark'' can also be used to refer to any distinguishing mark. General overview Historically, hallmarks were applied by a trusted party: the "guardians of the craft" or, more recently, by an assay office. Hallmarks are a guarantee of certain purity or fineness of the metal, as determined by official metal (assay) testing. Distinguishment Hallmarks are often confused with "trademarks" or "maker's marks". A hallmark is not the mark of a manufacturer to distinguish their products from other manufacturers' products: that is the function of trademarks or makers' marks. To be a true hallmark, it must be the guarantee of an independent body or authority that the contents are as marked. Thus, a stamp of "925" by itself is not, strictly speaking, a hallmark, ...

Krugerrand
The Krugerrand (; ) is a South African coin, first minted on 3 July 1967 to help market South African gold and produced by Rand Refinery and the South African Mint. The name is a compound of ''Paul Kruger'', the former President of the South African Republic (depicted on the obverse), and ''rand'', the South African unit of currency. On the reverse side of the Krugerrand is a pronking springbok, South Africa's national animal. By 1980 the Krugerrand accounted for more than 90% of the global gold coin market and was the number one choice for investors buying gold. However, during the 1980s and 1990s, Krugerrands fell out of favor as some western countries forbade import of the Krugerrand because of its association with the apartheid government of South Africa.Bob Secter (02 Oct 1985Reagan Bans Imports of S.

Sovereign (British Coin)
The sovereign is a British gold coin with a nominal value of one pound sterling (£1) and contains 0.2354 troy oz of pure gold. Struck since 1817, it was originally a circulating coin that was accepted in Britain and elsewhere in the world; it is now a bullion coin and is sometimes mounted in jewellery. In addition, circulation strikes and proof examples are often collected for their numismatic value. In most recent years, it has borne the design of Saint George and the Dragon on the reverse; the initials () of the designer, Benedetto Pistrucci, are visible to the right of the date. The coin was named after the English gold sovereign, which was last minted about 1603, and originated as part of the Great Recoinage of 1816. Many in Parliament believed a one-pound coin should be issued rather than the 21-shilling guinea that was struck until that time. The Master of the Mint, William Wellesley Pole had Pistrucci design the new coin; his depiction was also used for oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eagle (United States Coin)
The eagle was a United States $10 gold coin issued by the United States Mint from 1792 to 1933. The eagle was the largest of the five main decimal base-units of denomination used for circulating coinage in the United States prior to 1933, the year when gold was withdrawn from circulation. These five main base-units of denomination were the mill, the cent, the dime, the dollar, and the eagle, where a cent is 10 mills, a dime is 10 cents, a dollar is 10 dimes, and an eagle is 10 dollars. The eagle base-unit of denomination served as the basis of the quarter eagle ($2.50), half eagle ($5), eagle ($10), and double eagle ($20) coins. With the exceptions of the gold dollar coin, the gold three-dollar coin, the three-cent nickel, and the five-cent nickel, the unit of denomination of coinage prior to 1933 was conceptually linked to the precious or semi-precious metal that constituted a majority of the alloy used in that coin. In this regard the United States followed long-standing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Gold
Crown gold is a 22 karat (kt) gold alloy used in the crown coin introduced in England in 1526 (by Henry VIII). In this alloy, the proportion of gold is 22 parts out of 24 (91.667% gold)—and is appreciably less prone to wear than the softer 23 kt gold of earlier gold sovereigns—an important point for coins intended for everyday use in circulation. Alloying metal The alloying metal in England was, and is, traditionally restricted to copper. This is still used for the current British gold sovereign. An exception was for the gold sovereigns of 1887, when 1.25% silver, replacing the same weight of copper, was used to gain a better reproduction image of Queen Victoria for the Golden Jubilee of her reign. Elsewhere, both copper and silver have been used in varying proportions. Circulating coins In the United States until 1834, gold circulating coins were minted in 22 kt. crown gold—although using about 6% silver as well as copper. From 1834, the fineness of U.S. coin gold was dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ducat
The ducat () coin was used as a trade coin in Europe from the later Middle Ages from the 13th to 19th centuries. Its most familiar version, the gold ducat or sequin containing around of 98.6% fine gold, originated in Venice in 1284 and gained wide international acceptance over the centuries. Similarly named silver ducatons also existed. The gold ducat circulated along with the Florentine florin and preceded the modern British pound sterling and the United States dollar. Predecessors The word ''ducat'' is from Medieval Latin ''ducalis'' = "relating to a duke (or dukedom)", and initially meant "duke's coin" or a "duchy's coin". The first issue of scyphate billon coins modelled on Byzantine ''trachea'' was made by King Roger II of Sicily as part of the Assizes of Ariano (1140). It was to be a valid issue for the whole kingdom. The first issue bears the figure of Christ and the Latin inscription ''Sit tibi, Christe, datus, quem tu regis iste ducatus'' (meaning "O Christ, l ...

Chinese Gold Panda
The Chinese Gold Panda () is a series of gold bullion coins issued by the People's Republic of China.

There is also a Silver Panda series issued with the same designs as the Gold Panda coins. History China issued its first gold coins picturing a panda design in 1982, in sizes of of 99.9 fine gold. Beginning in 1983 another size was added – . Larger panda coins were issued in some years, weighing . These popular coins are issued in prooflike brilliant uncirculated quality with a different design each year. A freeze of the design was announced with the 2001 issues—and thus the 2002 pandas were identical to 2001. But collectors spoke up in behalf of annual changes, and China reverted to their original pol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Buffalo (coin)
The American Buffalo, also known as a gold buffalo, is a 24-karat bullion coin first offered for sale by the United States Mint in 2006. The coin follows the design of the Indian Head nickel and has gained its nickname from the American Bison on the reverse side of the design. This was the first time the United States Government minted pure (.9999) 24-karat gold coins for the public. The coin contains one-troy ounce (31.1g) of pure gold and has a legal tender (face) value of US$50. Due to a combination of the coin's popularity and the increase in the price of gold the coin's value has increased considerably. The initial 2006 U.S. Mint price of the proof coin was $800. In 2007 the price was $899.95, $1,410 in 2009, and $2,010 in 2011.
