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 decr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carat (purity)
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% g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Coins
A coin is a small, flat (usually depending on the country or value), round piece of metal or plastic used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. They are most often issued by a government. Coins often have images, numerals, or text on them. ''Obverse'' and its opposite, ''reverse'', refer to the two flat faces of coins and medals. 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''. Coins are usually made of metal or an alloy, or sometimes of man-made materials. They are usually disc shaped. Coins, made of valuable metal, are stored in large quantities as bullion coins. Other coins are used as money in everyday transactions, circulating alongside banknotes. Usually the highest value ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

The Great Debasement The Great Debasement (1544–1551) was a currency debasement policy introduced in 1544 England under the order of Henry VIII which saw the amount of precious metal in gold and silver coins reduced and in some cases replaced entirely with cheaper base metals such as copper. Overspending by Henry VIII to pay for his lavish lifestyle and to fund foreign wars with France and Scotland are cited as reasons for the policy's introduction. The main aim of the policy was to increase revenue for the Crown at the cost of taxpayers through savings in currency production with less bullion being required to mint new coins. During debasement gold standards dropped from the previous stan |
