倫敦奧運金牌是“銀”牌

　　奧運會金牌真的是金子做的嗎?當然不是!2012年倫敦奧運會的金牌雖然號稱為史上最大最重，但其實絕大部分的成分是銀，只是在表面鍍了一層金!所以，運動員們，切記不要用力咬金牌哦，說不定金牌就露陷了!

　　THE gold medals that will be awarded in London this year will be the biggest and heaviest handed out at any summer Olympics. At 400 grams (14 ounces) they will be 17 times heavier than at the 1912 Olympics in Stockholm. On the other hand, the 1912 games were the last one where gold medals were made entirely of gold. Now they consist mainly of silver with a thin coat of gold—6 grams is the minimum requirement. The London medal will have a goldcontent of only about 1.5%, and at current prices will be worth 6. Calculations by The Economist find that this is much more than the "podium value" of any previous gold medal (based on estimates of the composition of medals and bullion prices at the time, adjusted forinflation). This is partly because gold and silver prices are now historically high and partly because this year’s medal is so much heavier, even though the extra weight is silver rather than gold. For the first time, the silver in this year’s "gold" medal is actually worth more than its gold content. Moreover, if the metal content of earlier medals is valued at today’s bullion prices, the London gold is worth only just over half of those handed out in 1912.

　　2012年倫敦奧運會上所頒發的金牌將會是史上最大也是最重的金牌。每塊金牌重400克(14盎司)，其重量為1912年斯德哥爾摩奧運會金牌的17倍。不過，1912年奧運會是最后一屆采用純金打造金牌的奧運會。現在的金牌主要成分是銀，只在表面鍍一層不少于6克重的純金。本屆倫敦奧運會的金牌含金量僅為1.5%，折合現在的金價約為706美元(約合人民幣4250元)。根據《經濟學人》雜志的計算，倫敦奧運金牌的價值將超過以往任何一屆的金牌價值(根據當時的金牌成分和價值估算，并考慮了通貨膨脹的因素)，因為現在的金銀價格都達到了歷史最高點，即使多出來的重量是白銀而不是更貴的黃金。本屆倫敦奧運會金牌中的白銀價值首次超過了其中黃金的價值，而且如果把之前金牌含金量的價值按照現在的牌價計算的話，倫敦奧運會金牌的價值僅比1912年奧運會的一半多一點而已。
