A metal is deemed to be precious if it is rare. The discovery of new sources of ore or improvements in mining or refining processes may cause the value of a precious metal to diminish. The status of a “precious” metal can also be determined by high demand or market value. Precious metals in bulk form are known as bullion, and are traded on commodity markets. Bullion metals may be cast into ingots, or minted into coins. The defining attribute of bullion is that it is valued by its mass and purity rather than by a face value as money.

Many nations mint bullion coins. Although nominally issued as legal tender, these coins’ face value as currency is far below that of their value as bullion. For instance, Canada mints a gold bullion coin (the Gold Maple Leaf) at a face value of containing one troy ounce (31.1035 g) of golds of July 2009, this coin is worth about ,075 as bullion.[citation needed] Bullion coins’ minting by national governments gives them some numismatic value in addition to their bullion value, as well as certifying their purity.

The level of purity varies from issue to issue. 99.9% purity is common. The purest mass-produced bullion coins are in the Canadian Gold Maple Leaf series, which go up to 99.999% purity. Note that a 100% pure bullion is not possible, as absolute purity in extracted and refined metals can only be asymptotically approached. Many bullion coins contain a stated quantity (such as one troy ounce) of the marginally-impure alloy. In contrast, the Krugerrand is one of many historic and modern bullion coins of 22 Kt Crown gold, with a stated content (usually one troy ounce) of “fine gold”[clarification needed (define)], with the other component(s) of the alloy making the coin heavier than one ounce in total. Still more bullion coins (for example: British Sovereign) state neither the purity nor the fine-gold weight on the coin, but are recognized and consistent in their composition,[citation needed] and many historically stated a denomination in currency (example: American Double Eagle).

One of the largest bullion coins in the world is the 10,000 dollar Australian Gold Nugget coin minted in Australia which consists of a full kilogram of 99.9% pure gold. There have been a small number of larger bullion coins, but they are impractical to handle and not produced in mass quantities. China has produced coins in very limited quantities (less than 20 pieces minted) that exceed 260 troy ounces (8 kg) of gold.[citation needed] Austria has minted a coin containing 31 kg of gold (the Vienna Philharmonic Coin minted in 2004 with a face value of 100,000 euro). As a stunt to publicise the 99.999% pure one-ounce Canadian Gold Maple Leaf series, in 2007 the Royal Canadian Mint made a 100 kg 99.999% gold coin, with a face value of $ 1 million, and now manufactures them to order, but at a substantial premium over the market value of the gold.

Gold and silver are often seen as hedges against both inflation and economic downturn. Silver coins have become popular with collectors due to their relative affordability, and unlike most gold and platinum issues which are valued based upon the markets, silver issues are more often valued as collectables, far higher than their actual bullion value.

Aluminium

An example of a precious metal that is now common is that of aluminium. Although aluminium is one of the most commonly occurring elements on Earth, it was at one time found to be exceedingly difficult to extract from its various ores. This made the little available pure aluminium, which had been refined at great expense, more valuable than gold. Bars of aluminium were exhibited alongside the French crown jewels at the Exposition Universelle of 1855[citation needed], and Napoleon III’s most important guests were given aluminium cutlery, while those less worthy dined with mere silver. Additionally, the pyramidal top to the Washington Monument is made of pure aluminium. At the time of the monument’s construction, aluminium was as expensive as silver. Over time, however, the price of the metal has dropped; the invention of the Hall-Hroult process in 1886 caused the high price of aluminium to permanently collapse[citation needed].

Bismuth and tellurium

Bismuth and tellurium are the only two metals which have abundances less than 10-8 by mass part (g/g) in the Earth’s crust, but which are currently not of high economic value.[citation needed]

For coin collectors seeking the Silver Buffalo Coin, getting a coin in excellent condition is of the utmost importance. A commemorative Silver Buffalo Coin was created in 2001 which consists of approximately 90 percent pure silver. The commemorative coin is a replica of the original Buffalo Nickel first created by James Earle Fraser and cast between 1913 and 1938. On the front of the Buffalo nickel appeared the profile of a Native American and on the back a standing buffalo is visible. The same design appears on the commemorative coins created in 2001.

The commemorative Silver Buffalo Coin is fully endorsed and backed by the United States Mint. It is possible for buyers come across counterfeits of 2001 Silver Buffalo Coin in the market. One will find on genuine coins that the backside of the coin is inscribed with the words “IN GOD WE TRUST,” just beneath the words “United States of America.” The latter text is arched above the buffalo on the back of the coin. Just beneath the buffalo’s head on the coin, the words “E Plubribus Unum,” the Latin phrase meaning “Out of Many, One” appears. The latter words are indicative of genuine commemorative coins as such an inscription is not inscribed on replications.

On a genuine Silver Buffalo Coin, coin collectors can also easily spot the specific denomination just below the buffalo on the obverse side of the coin which should clearly read “One Dollar.” Replications may display the words “giant buffalo proof” where the denomination amount appears on genuine coins. In addition, just below the denomination indicator on the obverse side of the coin, one will find the letter “P” which is an indicator of what mint cast the Silver Buffalo coin as well as the letter “F” which is indicative of the coin’s original designer. The uncirculated version of silver Buffalo coin is minted in Denver, CO, with a “D” Mint Mark inscribed on the coin instead. Another clear clue that the coin is genuine is the fact that on the front side of the coin on the lower left is the engraved year: “2001.”

Careful examination of the Silver Buffalo Coin will give a coin collector a solid idea about what he or she is buying. It is easy to separate all of the replicas from the originals when one knows what to look for. Understanding the identifying markers will help the coin collector ensure he or she is getting a genuine coin in every instance. You can also subject it to the magnet test. A silver coin won’t be attracted to the magnet, but a fake steel coin would.
