Trevor Ashmore
Trevor Ashmore is a coin counterfeiter infamous for producing modern copies of ancient English coins in the 1960s. Ashmore was a part-time coin dealer in the late 1960s and early 1970s. As he was a precision engineer he also made experimental coin dies. In 1972 he set up the company 'Period Coins' in Sutton-in-Ashfield producing replica coins, selling mostly to numismatists in the United States. The business eventually failed but he remained in production of replica coins. After retirement in 1991 he began to produce forged coins commercially again. Ashmore tended to concentrate on silver coins, which are especially dangerous to collectors since they are not hallmarked; his coins have appeared in the IBSCC's Bulletin on Counterfeits as well as Spink's Numismatic Circular The ''Numismatic Circular'' is an international periodical published by Spink since 1892 based in London. Now published six times a year, the ''Circular'' offers coins, books and banknotes for sale at fix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coin Counterfeiting
Coin counterfeiting of valuable antique coins is common; modern high-value coins are also counterfeited and circulated.Coin Counterfeiting Counterfeit Coins (2007-26-09) Counterfeit antique coins are generally made to a very high standard so that they can deceive experts. This is not easy and many coins still stand out. History Counterfeits of higher-value coins in circulation, designed for general circulation at face value, have been made by criminals for thousands of years.Circulating coins For modern coins in general circulation, the most common method of protection from forgeries is the use of bi-metallic coins made of two |
English Coins
The standard circulating coinage of the United Kingdom, British Crown Dependencies and British Overseas Territories is denominated in pennies and Pound (currency), pounds Pound sterling, sterling (pound sign, symbol "£", commercial GBP), and ranges in value from Penny (British decimal coin), one penny sterling to two pounds. Since Decimal Day, decimalisation, on 15 February 1971, the pound has been divided into 100 (new) pence. Before decimalisation, twelve Penny (British pre-decimal coin), pence made a Shilling (British coin), shilling, and twenty shillings made a pound. British coins are minted by the Royal Mint in Llantrisant, Wales. The Royal Mint also commissions the coins' designs. In addition to the circulating coinage, the UK also mints commemorative decimal coins (Crown (British coin), crowns) in the denomination of five pounds. Ceremonial Maundy money and bullion coinage of gold sovereigns, half sovereigns, and gold and silver Britannia coins are also produced. Som ...

Precision Engineering
Precision engineering is a subdiscipline of electrical engineering, software engineering, electronics engineering, mechanical engineering, and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances, are repeatable, and are stable over time. These approaches have applications in machine tool A machine tool is a machine for handling or machining metal or other rigid materials, usually by cutting, boring, grinding, shearing, or other forms of deformations. Machine tools employ some sort of tool that does the cutting or shaping. All ...s, MEMS, NEMS, optoelectronics design, and many other fields. Overview Professors Hiromu Nakazawa and Pat McKeown provide the following list of goals for precision engineering: # Create a highly precise movement. # Reduce the dispersion of the product's or part's function. # Eliminate fitting and promote assembly, especially automatic assembly. # Reduce the initial co ...

Coining (mint)
Minting, coining or coinage is the process of manufacturing coins using a kind of stamping, the process used in both hammered coinage and milled coinage. This "stamping" process is different from the method used in cast coinage. A coin die is one of the two metallic pieces that are used to strike a coin, one per each side of the coin. A die contains an inverse version of the image to be ''struck'' on the coin. ''Striking'' a coin refers to pressing an image into the blank metal disc, or planchet, and is a term descended from the days when the dies were struck with hammers to deform the metal into the image of the dies. Modern dies made out of hardened steel are capable of producing many hundreds of thousands of coins before they are retired and defaced. Ancient coin dies Prior to the modern era, coin dies were manufactured individually by hand by artisans known as engravers. In demanding times, such as the crisis of the Roman Empire in the 3rd century, dies were still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Numismatist
A numismatist is a specialist in numismatics ("of coins"; from Late Latin ''numismatis'', genitive of ''numisma''). Numismatists include collectors, specialist dealers, and scholars who use coins and other currency in object-based research. Although use of the term numismatics was first recorded in English in 1799, people had been collecting and studying coins long before this, all over the world. The first group chiefly derives pleasure from the simple ownership of monetary devices and studying these coins as private amateur scholars. In the classical field amateur collector studies have achieved quite remarkable progress in the field. Examples are Walter Breen, a well-known example of a noted numismatist who was not an avid collector, and King Farouk I of Egypt was an avid collector who had very little interest in numismatics. Harry Bass by comparison was a noted collector who was also a numismatist. The second group are the coin dealers. Often called professional numismatis ...

Silver Coin
Silver coins are considered the oldest mass-produced form of coinage. Silver has been used as a coinage metal since the times of the Greeks; their silver drachmas were popular trade coins. The ancient Persians used silver coins between 612–330 BC. Before 1797, British pennies were made of silver. As with all collectible coins, many factors determine the value of a silver coin, such as its rarity, demand, condition and the number originally minted. Ancient silver coins coveted by collectors include the Denarius and Miliarense, while more recent collectible silver coins include the Morgan Dollar and the Spanish Milled Dollar. Other than collector's silver coins, silver bullion coins are popular among people who desire a "hedge" against currency inflation or store of value. Silver has an international currency symbol of XAG under ISO 4217.

Coin Designers
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 valu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
