中國體育代表團已經在東京奧運會上奪得9枚金牌。中國健兒捧起金牌的時刻令我們激動不已，不少觀眾都守在電視機前為他們加油助威。

細心的觀眾可能注意到，往屆奧運會上，冠軍們在拿到金牌后喜歡用牙咬一下，尤其是拍照的時候。這不禁讓人好奇，奧運會的金牌是純金的嗎?

奧運會金牌最初確實是純金的，比如1904年、1908年和1912年的奧運會金牌就是由純金打造。

If the International Olympic Committee still gave solid gold medals to first place finishers, said medals may be pretty valuable. But after the 1912 Games, they made the switch to silver medals coated in gold.

如果國際奧委會仍然給冠軍選手頒發純金金牌，那么獎牌可能是非常值錢的。但是在1912年奧運會之后，國際奧委會將純金金牌換成了鍍金的銀牌。

據東京奧組委介紹，東京奧運會的金牌由約6克的黃金和約550克的純銀組成，所有的獎牌均由廢舊電器、電子產品中提煉的金屬 *** 。

【小知識】日本從2017年4月1日開啟了對廢舊手機家電的搜集活動，耗時兩年在全國收集了約78985噸小家電和621萬部舊手機從中提煉得純金約32公斤，純銀約3500公斤以及銅約2200公斤，所有的獎牌均來自這些回收提煉的金屬。

The gold medals for the Tokyo Olympics, created by Japanese designer Junichi Kawanishi, comprise roughly 6 grams of gold atop roughly 550 grams of pure silver. Since gold and silver rates, like stock prices, fluctuate pretty frequently, the value of the medal isn’t exactly static. But in general, it’s hovering somewhere above $800. A silver medal, made of 550 grams of pure silver, comes in at $462; and bronze medals, mostly copper and a little zinc, are worth just a few bucks.

東京奧運會的金牌由川西純市操刀設計，由大約6克的黃金和大約550克的純銀組成。由于黃金和白銀的價格和股票價格一樣，波動非常頻繁，因此獎牌的價值并不是一成不變的。但總體而言，金牌價值在800美元左右(約合人民幣5181元)。一枚由550克純銀制成的銀牌價值約為462美元(約合人民幣2992元);而銅牌，主要是由銅和少量鋅制成，只值幾美元。

But Olympic gold medals have value beyond the sum of their parts, and plenty of athletes have hocked them for much more than a paltry $800 or so. Mark Wells, a member of the “Miracle on Ice” US hockey team of 1980, sold his to a private collector, who auctioned it off for nearly $311,000 in 2010. Wells’s teammate, Mark Pavelich, made $262,900 off his own medal four years later.
