Libertad (coin)
The Libertad coins are silver and gold bullion coins originating from Mexico and minted by the La Casa de Moneda de México (''Mexican Mint''). The Mexican Mint was established in 1535 and is the oldest mint in the Americas. The modern coins contain 99.9% silver or gold (.999 fineness) and are available in various sizes. Both metal coins have undergone a design change. In 1989, 3,500 ounce Libertad platinum coins were produced. Libertads are devoid of face value, yet are legal tender, still accepted as currency and guaranteed by Banco de México, based on the market value of its gold or silver content. In addition to the bullion version, a proof and reverse proof versions for both metals are manufactured specifically for collectors. Gold coins made before 2000 are only 90% pure gold. Proof coins contain a frosted angel with a polished background. A reverse proof is the opposite and has a polished angel with a frosted background. An antique finish silver Libertad coin was first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold
Gold is a chemical element; it has chemical symbol Au (from Latin ) and atomic number 79. In its pure form, it is a brightness, bright, slightly orange-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactivity (chemistry), reactive chemical elements, being the second-lowest in the reactivity series. It is solid under standard temperature and pressure, standard conditions. Gold often occurs in free elemental (native state (metallurgy), native state), as gold nugget, nuggets or grains, in rock (geology), rocks, vein (geology), veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bullion Coin
A bullion coin (also known as a specie) is a coin struck from highly refined precious metal (bullion) and kept as a store of value or an investment rather than used in day-to-day commerce, or collectable, with numismatic value beyond that of its metal content. A bullion coin is distinguished by its weight (or mass) and fineness on the coin. Unlike rounds, bullion coins are minted by government mints and have a legal tender face value. Bullion coins can have fineness ranging from 91.9% (22 karat) to 99.99% purity (24 karat). In the United Kingdom coins deemed to be investment coins are exempt from value-added tax (VAT) on transactions. A coin is considered to be an investment coin if it was minted after 1800, and at least 900 thousandths fine, and has been legal tender in its country of origin, and not normally sold at more than 180% of the value of its precious metal content; or if it is on a long list of coins deemed to be investment coins.

Bullion
Bullion is non-ferrous metal that has been refined to a high standard of elemental purity. The term is ordinarily applied to bulk metal used in the production of coins and especially to precious metals such as gold and silver. It comes from the Anglo-Norman term for a melting-house where metal was refined, and earlier from French , "boiling". Although precious metal bullion is no longer used to make coins for general circulation, it continues to be held as an investment with a reputation for stability in periods of economic uncertainty. To assess the purity of gold bullion, the centuries-old technique of fire assay is still employed, together with modern spectroscopic instrumentation, to accurately determine its quality. As investment The specifications of bullion are often regulated by market bodies or legislation. In the European Union, the minimum purity for gold to be referred to as "bullion", which is treated as investment gold with regard to taxation, is 99.5% for ...

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 ...

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.

Troy Weight
Troy weight is a system of units of mass that originated in the Kingdom of England in the 15th century and is primarily used in the precious metals industry. The troy weight units are the grain, the pennyweight (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). The troy grain is equal to the grain unit of the avoirdupois system, but the troy ounce is heavier than the avoirdupois ounce, and the troy pound is lighter than the avoirdupois pound. Legally, one troy ounce (oz t) equals exactly 31.1034768 grams. Etymology Troy weight is generally supposed to take its name from the French market town of Troyes where English merchants traded at least as early as the early 9th century. The name ''troy'' is first attested in 1390, describing the weight of a platter, in an account of the travels in Europe of the Earl of Derby. Charles Moore Watson (1844–1916) proposes an alternative etymology: ''The Assize of Weights and Measures'' (also known a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iztaccihuatl
Iztaccíhuatl or Ixtaccíhuatl (both forms also spelled without the accent) ( or, as spelled with the x, ) is a dormant volcanic mountain in Mexico located on the border between the State of Mexico and Puebla within Izta-Popo Zoquiapan National Park. It is the nation's third highest, after Pico de Orizaba at , and Popocatépetl at . The name "Iztaccíhuatl" is Nahuatl for "White (like salt) woman", reflecting the four individual snow-capped peaks which depict the head, chest, knees and feet of a sleeping female when seen from east or west. Iztaccíhuatl is to the north of its twin Popocatépetl, to which it is connected by the high altitude Paso de Cortés. Depending on atmospheric conditions Iztaccíhuatl is visible much of the year from Mexico City some to the northwest. The first recorded ascent was made in 1889, though archaeological evidence suggests the Mexica and previous cultures climbed it previously. It is the lowest peak containing permanent snow and glaciers in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (mythology)
In ancient Roman religion Victoria was the deified personification of victory. She first appeared during the first Punic War, seemingly as a Romanised re-naming of Nike, the goddess of victory associated with Rome's Greek allies in the Greek mainland and in Magna Graecia. Thereafter she comes to symbolise Rome's eventual hegemony and right to rule. She is a deified abstraction, entitled to a cult. But unlike Nike, she has virtually no mythology of her own. History and iconography Victoria first appears during the first Punic War, as a translation or renaming of Nike, the Greek goddess of victory in peace or war. Nike would have become familiar to the Roman military as a goddess of Rome's Greek allies in the Punic Wars. She was worshipped in Magna Graecia and mainland Greece, and was a subject of Greek myth. Around this time, various Roman war-deities begin to receive the epithet ''victor'' (conqueror) or ''invictus'' (unconquered). By the late republican and early imper ...

Centenario (coin)
The Centenario is a Mexican gold bullion coin first minted in 1921 to commemorate the 100th anniversary of Mexico's independence from Spain. The coin is not intended to be used as currency; the face value of 50 Mexican peso, pesos is for legal purposes only, and does not reflect the actual value of the gold content. The obverse and reverse, obverse of the Centenario contains the image of Winged Victory (El Ángel, ''El Ángel de la Independencia'': "The Angel of Independence"), with a laurel wreath in her right hand and broken chains in her left. Two famous Mexican volcanoes, Popocatepetl and Iztaccíhuatl, rise in the background. The 1821 on the lower left commemorates the year of Mexico's independence. The date on the right indicates year of mintage, with the 1921 and 1931 (the last year of the original series) mintages being particularly valuable. Production restarted in 1943 due to the demand for gold coins, and coins minted between 1949 and 1972 are usually marked "1947". Th ...

Codex Mendoza
The Codex Mendoza is an Aztec codices, Aztec codex, believed to have been created around the year 1541. It contains a history of both the Aztec rulers and their conquests as well as a description of the daily life of pre-conquest Aztec society. The codex is written using traditional Aztec pictograms with a translation and explanation of the text provided in Spanish language, Spanish. It is named after Don (honorific), Don Antonio de Mendoza (1495-1552), the viceroy of New Spain, who supervised its creation and who was a leading patron of native artists. Mendoza knew that the ravages of the conquest had destroyed multiple native artifacts, and that the craft traditions that generated them had been effaced. When the Spanish crown ordered Mendoza to provide evidence of the Aztec political and tribute system, he invited skilled artists and scribes who were being schooled at the Franciscan college in Tlatelolco to gather in a workshop under the supervision of Spanish priests where t ...

Coin Week
''CoinWeek'' is an American internet-based publication that publishes articles, analysis, news, videos and podcasts about a wide range of numismatic topics. It is one of the leading online publications for coin collectors in the North American market, winning more than two-dozen Numismatic Literary Guild (NLG) Awards since its launch in 2011. Founding and early history (2010–2014) Work began on ''CoinWeek'' in 2010 as an evolution of the website ''CoinLink'', founded by Scott Purvis in 1995. ''CoinLink'' was one of the Internet's first numismatic resources that connected coin dealers to collectors, presenting collectors with lists and profiles of many of the rare coin industry's leading dealers. As the site evolved, it began to aggregate press releases and news articles from the industry's leading companies and offer collectors original news and editorial content—such as articles by numismatic blogger Greg Reynolds, among others. In 2009, Purvis conceptualized a new website ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
