Coins Of The Australian Dollar
Coins of the Australian dollar were introduced on 14 February 1966, although they did not at that time include the one-dollar or two-dollar coins. The dollar was equivalent in value to 10 shillings (half a pound) in the former currency. Regular coinage Produced by the Royal Australian Mint, all current coins have featured four versions of the effigy of Her Majesty Elizabeth II, former Queen of Australia, on the obverse. The first effigy was designed by Arnold Machin, the second effigy by Raphael Maklouf, the third effigy by Ian Rank-Broadley and the fourth effigy by artist Jody Clark. They have all been matched with designs by the Australian-born artist Stuart Devlin on the reverse. The set now comprises a 50c, 20c, 10c and 5c coin, all still referred to as "silver", although they consist of 75% copper and 25% nickel. For many years there were also 2c and 1c coins, traditionally called "copper" coins, although they are actually an alloy of copper and zinc. The original 50 ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

United States Coinage
Coins of the United States dollar (aside from those of the earlier Continental currency) were first minted in 1792. New coins have been produced annually and they make up a valuable aspect of the United States United States currency, currency system. Today, circulating coins exist in denominations of 1¢ (i.e. 1 cent (currency), cent or $0.01), 5¢, 10¢, 25¢, 50¢, and $1.00.

The main mint is the Philadelphia Mint, which produces circulating coinage, mint sets and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coin Orientation
Coin orientation (or coin alignment or variations of these) is the relation of the vertical orientation of the images on the obverse and reverse sides of coins to one another. The two basic relations are called ''medallic orientation'' and ''coin orientation''. Medallic orientation Medallic orientation (or ''medal alignment'', or variations of these) derives its name from medals tagged to a uniform. For a medal to display properly, when the obverse of the medal is right side up, a left or right turn must show the reverse also to be right side up. In other words, the tops of the obverse and reverse share the same position. In Britain this is sometimes called "British turnover". British coinage, most other Commonwealth coinage, Japanese yen coinage, and Euro coinage have medallic orientation. Coin orientation ''Coin Alignment'' or ''Coin orientation'' is present when the top of the designs are aligned opposite of each other. The concept originated as a western style that was ad ...

Euro Coins
There are eight euro coin denominations, ranging from one cent to two euros (the euro is divided into a hundred cents). The coins first came into use in 2002. They have a common reverse, portraying a map of Europe, but each country in the eurozone has its own design on the obverse, which means that each coin has a variety of different designs in circulation at once. Four European microstates that are not members of the European Union (Andorra, Monaco, San Marino, and the Vatican City) use the euro as their currency and also have the right to mint coins with their own designs on the obverse side. The coins, and various commemorative coins, are minted at numerous national mints across the European Union to strict national quotas. Obverse designs are chosen nationally, while the reverse and the currency as a whole is managed by the European Central Bank (ECB). History The euro came into existence on 1 January 1999. It had been a goal of the European Union (EU) and its predecessors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
