金币乱弹 （二）

Highway

前文说了(金币乱弹 （一）)，南非的克鲁格金币做了带头大哥，那么大家一定好奇了，这老二的位置给谁了呢？

我个人认为，这金币界第二把交椅应该是轮加拿大的枫叶币了。

七八十年代南非的克鲁格金币走俏了以后，眼红的可不止一家。那时候南非在搞种族歧视得到全世界的制裁，它的金币理论上都是被禁运的。这正好是个契机，所以很多国家都是在那个期间进场的，都想在国际金币市场上分一杯羹。

加拿大是冲在最前面的一个（我们中国人动作也不算慢），并且看样子是下了狠心，一定要玩个大的。

加拿大一出手就是上的纯金，一开始比较谨慎，上的是三九金（99.9%），四年后（1982年），一咬牙上了四九金（99.99%），最近几年发了疯，搞什么限量版，整五九金（99.999%），这可是全球独一份。

图案设计上，加拿大走的也是“老成持重”路线，一面是加拿大的标志性枫叶，一面是英国女王伊丽莎白二世（老中青各个年级段的都有，见下图）。并且加拿大还通过了法律，确认了枫叶币的货币地位（legal tender)，可以堂而皇之的打上面值，成为“官币”。

当然了，仅靠纯度高一项是不能肃立全球品牌的，为此，加拿大皇家造币局实行了一窝蜂战术，全方面立体交叉的一起上。上金币，上银币，上钯币，上铂金币。。。基本上所有的贵重金属都拿来溶了铸一把。并且从大到小全面全面覆盖。从小的1/20盎司到大的100公斤，统统来一遍。

100公斤？搞错没有？

没有搞错。2010年加拿大还真是铸了100公斤的超级金币，面值1百万。原定计划是作为镇宅之宝，不出售的。但后来禁不住诱惑，327万欧元给卖了。你们要是有钱的话，可以打电话订购，他们现在承接这种业务。到现在至少5枚这种巨无霸已经出手了。

就我个人而言，不是很喜欢枫叶币。因为设计有些阴柔（女王换过好几次，枫叶没变过），不够给力，另外它半径很小，是所有金币里最小的一种。虽然要厚一些，但是拿在手里的感觉不是特好。

那一百公斤那种拿在手里感觉还好啊？

Too damn heavy, 估计得给我把胳膊给整折了！

你打电话order的时候可以跟他们讲一下，说就不要铸成金币样了，弄个“小金墩”样就成，这样回了家好处置！

买金币金条还真是比在Amazon买东西麻烦。卖家一般不接受信用卡（因为信用卡公司要吃2%+的手续费），如果卖家收信用卡的话，价格也会高一截。

虽然不收信用卡，但你网上下单的时候他们要你的信用卡信息，以防你反悔。你下了单以后，要马上寄个人支票/银行本票过去，或者直接电汇。他们受到钱后，一般数日之内会将东西寄出。这玩意儿你还一定的在家签收才行。

纯度是4个9，或者5个9肯定是忽悠，以前在国内的时候听从事这方面工作的人说过，现在的技术不可能加工到那个 ...

我觉得不是。国外这方面要求还是很严的。如果不符实，别人可以起诉你的。并且这都是“国币”，成分和含量都是公开的。有了问题，你可以起诉该国政府。

你看铂金金币，就标着9995，而不是9999，所以那几个字不是写着玩的，是有原因的。全世界到目前也就是加拿大一家出99999纯度的黄金，别家还真没有。

中国的国币熊猫币到现在也就是99.9%，也许我们技术上还有些问题。但是按照纯度的算法，24K金就是99.9% or higher。所以中国的熊猫币还是正儿八经的24K金币的。用香港那面的术语来说，中国的熊猫币是千足金币，美国buffalo，加拿大maple和澳大利亚袋鼠币是万足金币。

不是我故意败你的兴致，不过我了解的情况真的不是这样的。
这些是约定成俗的说法，就像2 by 4不是真的2英 ...

你那位朋友的知识曾经是对的，但是需要更新了。

工业界大概在40年前就可以生产9999纯度的黄金了，美国业界大概是1982年成熟的，加拿大看来要早几年。除了中国，世界上主要的金币生产国都是9999纯度的黄金了（南非的格鲁巴和美国的鹰币例外，是22K金）。

这里有篇文章，你可以看看。如果有兴趣的话，不妨转给那位朋友，让他也更新一下知识。

Refining Gold Explained!
The process of refining gold is necessary to obtain gold of the greatest possible purity from a myriad of sources.  These may include industrial scrap, recycling banks, primary producers of precious metals, dealers, financial institutions, and mints. The mechanical preparation and concentration of ore is termed ore dressing; it produces gold that is often an admixture with trace impurities and some silver. Further treatment is necessary to remove the contaminants in freeing and refining gold.

Refining gold may be done by any of several methods, all quite technologically advanced. Huge amounts of refined gold are produced by some of the biggest refineries in the United States: the capacity to produce more than 10 million troy ounces each year is not unusual.  During the past 40 years or so, the standard methods of refining gold were able to produce gold that was .9999 fine.  In 1982, bullion coins of .9999 purity were produced by the best American refineries.  Today one can buy the first American solid gold 24K bullion coin, the American Buffalo $50 coin. On the obverse (heads) side is shown the profile of a Native American chief, and on the reverse (tails) side, a picture of the buffalo. The weight, content, and purity of this .9999 fine coin are guaranteed by the US government.  The coin sells for $918.77!  The most highly-developed technological processes of the present day for refining gold yield a gold that is .99999 pure, to be used for granulation – a technique of jewelry embellishment that solders tiny spherical droplets of gold onto a base.

These are the two stages of the process of refining gold:
•    The feed material of gold ore is treated with the Miller chlorination process, a pyrometallurgical operation in which the gold is heated in crucibles until melted, then exposed to chlorine gas. Although chlorine does not react with gold, it does combine with silver and other impurities in the ore to form chlorides. These float to the surface and can be skimmed off to leave behind gold that is .995 pure and therefore meets the requirements of the London bullion market.
•    Some end-use customers require gold that is even more pure. The .995 pure gold is cast into anodes. These are placed in an electrolyte solution, along with cathodes of pure gold. When an electric current passes from anode to cathode through the electrolyte solution, the anodes dissolve, and the pure gold in them passes to the cathodes. It is a long process of refining gold, requiring about two days, but it does produce gold that is .99999 pure. At the end of the operation, the gold-coated cathodes are removed, molten, and cast into bars.

Another process for refining gold treats it with sulphuric, nitric, and hydrochloric acids. These do not react with gold, but do react with impurities. In the final stage of this process, the purified gold is molten and cast into bars weighing approximately 28 pounds.

Still another way of refining gold is the fire assay process, using the technique of cupellation.  This is an old technique that was used to separate silver or gold from lead or other base metals. Essentially, an alloy of gold and other metals, including lead, is melted at a high temperature and then allowed to freeze. When it is cooled, a small amount of precious metal (gold and silver) and lead remains, and a slag is formed of base metals and other impurities. The “button” of gold and silver is again subjected to extremely high heat; the lead oxidizes and goes into the atmosphere. Finally, the small piece of gold and silver is placed in nitric acid, which dissolves the silver and leaves the 24K pure gold. This ancient method of refining gold should only be used for small quantities of gold, not more than 10 grams, because the process emits large quantities of highly toxic lead oxide fumes.

For refining gold in larger quantities, a more ecologically-sound technique can be used; for example, inquartation and parting.  This involves melting the gold to be refined in an alloy with silver or copper, such that the gold makes up about 25 percent of the alloy. The base metal is then dissolved in acid, preferably nitric acid, which removes all but the gold.  The resulting gold sludge may be treated with a secondary bath of hydrochloric acid, and is then washed and drained. Inquartation and parting has been found to be useful in treating gold scrap of 10K to 14K; the necessary additions of silver or copper may already be present in the scrap material.  It should be noted that these last three processes for refining gold must only be performed in an appropriately specialized industrial environment.

On a very much smaller scale, refining gold at home is even possible. Chemical kits requiring a minimum of equipment are available; usually you only need a battery charger with DC current and a few Pyrex glass vessels. Such kits purport to be completely safe, and are sold as science experiments for older children. Look on the Internet to find more details about suppliers.

国外铸币，尤其是那种有Face Value的国币都是按照法律条纹来生产的。譬如美国的鹰币就是国会通过了Gold Bullion Coin Act of 1985以后才依法铸造的，美国政府要保证它的品质的。加拿大的枫叶币是根据Canadian Currency Act and the Royal Canadian Mint Act两项法令来铸造的。这和和小贩产果汁是两码事儿。

问一下， 第二张上的金币为啥有红点？我有一块5g的迷你金条， 也有一个小红点。 ...

他们管这些“红点”叫 Copper spot。其原因吗，应该是金币里的微量杂质引起的，比如说常见的铜。

这些点子可以被除去的，但是不建议个人去搞，因为弄不好会对金币有损害的。

不知道啥价格，要不也整个2两尝尝鲜

一般的金币就是市场金价加50-100刀左右，很简单的。

老币，稀币，有收藏价值的另算，没有什么程式，和集邮差不多一个道理。

我的部分存货。

澳大利亚的金币有个小塑料盒，别家的包装都很简单。

24K金比较软，所以要是收藏的话，上网买那种透明塑料盒（coin capsules），效果很好。就是买的时候要看仔细了，因为各家金币的大小不一样。。。

好像纪念性金币会有首饰盒子之类的漂亮包装，当然价格也较高，大概是因为与首饰一样包含了设计和加工等额 ...

礼品包装的金币要贵一些，经过认证机构认证的金币要贵一些，譬如世界上著名的那两家认证公司。有没有必要付这个冤枉钱呢，大家各执一词，所以不好说。

价格最贴近金价的是大块的金锭，比如一公斤的或是更大的。小金币的相对价格是最高的，所以我不建议买。金饰就更别提了。一到五盎司的金币我个人觉得比较适宜。

谢谢指教！再打听一下，为啥老轧你总是在网上买，而不是向银行买，按说银行的牌牌更靠谱不是？ ...

美国银行不怎么经销金币，倒是很多网站专卖的，价格也不错。我从Ebay上买了很多，还跟私人卖家打过交道，总体尚好。有过一些问题，但也都解决了。
