Gold Medal
A gold medal is a medal awarded for highest achievement in a non-military field. Its name derives from the use of at least a fraction of gold in form of plating or alloying in its manufacture. Since the eighteenth century, gold medals have been awarded in the arts, for example, by the Royal Danish Academy of Fine Arts, usually as a symbol of an award to give an outstanding student some financial freedom. Others offer only the prestige of the award. Many organizations now award gold medals either annually or extraordinarily, including various academic societies. While some gold medals are solid gold, others are gold-plated or silver-gilt, like those of the Olympic Games, the Lorentz Medal, the United States Congressional Gold Medal and the Nobel Prize medal. Nobel Prize medals consist of 18 karat green gold plated with 24 karat gold. Before 1980, they were struck in 23 karat gold.

Award
An award, sometimes called a distinction, is given to a recipient as a token of recognition of excellence in a certain field. When the token is a medal, ribbon or other item designed for wearing, it is known as a decoration. An award may be described by three aspects: 1) to whom it is given to 2) what 3) by whom, all varying according to purpose. The recipient is often awarded to an individual, a student, athlete or representative of a group of people, be it an organisation, a sports team or a whole country. The award item may be a decoration or an insignia suitable for wearing, such as a medal, badge, award pin or rosette. It can also be a token object such as a certificate, diploma, championship belt, trophy or plaque. The award may also be accompanied by a title of honor, and an object of direct cash value, such as prize money or a scholarship. Furthermore, an is an award given, typically in education, that does not confer the recipient(s) a higher standing but is ...

Association Of Applied Geochemists
The Association of Applied Geochemists (AAG) is an international society that seeks to advance the study and application of geochemistry and represents scientists working in that field. History The society was founded in 1970 as the Association of Exploration Geochemists. Membership Members of the society are required to have worked in geochemistry for at least two years at the time of application; student members are admitted if they are enrolled in courses recognised by the Association. To become a voting member, or fellow, members must satisfy the society that they have adequate training and experience in the field. Membership in the society has been used to measure total numbers of working geochemists. Activities Symposia The Association organizes a series of biennial International Applied Geochemistry Symposia (titled the International Geochemical Exploration Symposium until 2005), held recently in Oviedo, Spain, and Perth, Australia.

Geochemistry
Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System, and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt. It is an integrated field of chemistry and geology. History The term ''geochemistry'' was first used by the Swiss-German chemist Christian Friedrich Schönbein in 1838: "a comparative geochemistry ought to be launched, before geognosy can become geology, and before the mystery of the genesis of our planets and their inorganic matter may be revealed." However, for the rest of the century the more common term was "chemical geology", and there was little contact between geologists and chemists. Geochemistry emerged as a separate discipline after ...

Minted 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 first mint was likely established in Lydia in the 7th century BC, for coining gold, silver and electrum. The first coins known to be minted on Europe ...

Silver
Silver is a chemical element; it has Symbol (chemistry), symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form ("native metal, native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
