[5E.硬幣]：Coin，http://en.wikipedia.org/wiki/Coins中文

<5E.1.中文> 硬幣，http://zh.wikipedia.org/wiki/%E7%A1%AC%E5%B9%A3

硬幣（Coins）是指以堅硬的物料（通常是金屬）造成的貨幣。相對紙幣，硬幣的面值通常較低。一般硬幣是由非貴重金屬（如銅、鎳）鑄造，由政府發行，一般為輔幣，其面值通常是靠法律規定。但收藏性的硬幣則多以貴重金屬（如金、銀）鑄造，這些硬幣帶有內在的價值，因此其價格與發行者無大關係。 

        在一些地區，隨著各種諸如八達通般的電子收費系統的流行，硬幣的使用已越來越少，慢慢退出歷史舞台。 

近代中國流通的外國硬幣： 

  馬劍，荷蘭銀元，上面有一騎馬持劍勇士圖案。 

  雙柱，也稱"本洋"，西班牙銀元，一面圖案上面一盾牌，其左右有一對海克力士柱子。 

  鷹洋，俗稱「蝙蝠」，墨西哥銀元，有一隻展翅雄鷹圖案。 

  坐洋，法國安南（西貢）銀元，上面有一自由女神坐像。 

  龍洋，日本銀元，上面有龍圖案。 

  站人洋，英國銀元，圖案是站立大不列顛女神。

<5E.2.英文> Coin，http://en.wikipedia.org/wiki/Coin

A coin is a piece of hard material, usually metal or a metallic material, usually in the shape of a disc, and most often issued by a government. Coins are used as a form of money in transactions of various kinds, from the everyday circulation coins to the storage of vast numbers of bullion coins. In the present day, coins and banknotes make up the cash forms of all modern money systems. Coins made for circulation (general monetized use) are usually used for lower-valued units, and banknotes for the higher values; also, in most money systems, the highest value coin made for circulation is worth less than the lowest-value note. The face value of circulation coins is usually higher than the gross value of the metal used in making them, but this is not generally the case with historical circulation coins made of precious metals. For example, the historical Eagle contained .48375 troy ounce of gold and has a face value of only ten U.S. dollars, but the market value of the coin, due to its metal content, is now many times the face amount.

        Exceptions to the rule of coin face-value being higher than content value, also occur for some "bullion coins" made of silver or gold (and, rarely, other metals, such as platinum or palladium), intended for collectors or investors in precious metals. For examples of modern gold collector/investor coins, the United States mints the American Gold Eagle, Canada mints the Canadian Gold Maple Leaf, and South Africa mints the Krugerrand. The American Gold Eagle has a face value of US$50, and the Canadian Gold Maple Leaf coins also have nominal (purely symbolic) face values (e.g., C$50 for 1 oz.); but the Krugerrand does not.

        Historically, a great number of coinage metals (including alloys) and other materials have been used practically, impractically artistically, and experimentally in the production of coins for circulation, collection, and metal investment, where bullion coins often serve as more convenient stores of assured metal quantity and purity than other bullion^[1] .

        Coins have long been linked to the concept of money, as reflected by the fact that in other languages the words "coin" and "currency" are synonymous. Fictional currencies may also bear the name coin (as such, an item may be said to be worth 123 coin or 123 coins).
