Bullion Information
A precious metal is a rare, naturally occurring metallic chemical element of high economic value. Chemically, the precious metals are less reactive than most elements, have high lustre, are softer or more ductile, and have higher melting points than other metals. Historically, precious metals were important as currency, but are now regarded mainly as investment and industrial commodities. Gold, silver, platinum, and palladium each have an ISO 4217 currency code.
The best-known precious metals are the coinage metals gold and silver. While both have industrial uses, they are better known for their uses in art, jewellery and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded.[1]
Assortment of precious metalsThe demand for precious metals is driven not only by their practical use, but also by their role as investments and a store of value. Historically, precious metals have commanded much higher prices than common industrial metals.

Bullion
Silver 1000oz barA 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.[2]
Purity and Mass
A 500 gram silver bullion bar produced by Johnson MattheyThe 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 impossible, as absolute purity in extracted and refined metals is 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" or 100% pure gold, 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).
Coinage

For instance, Canada mints a gold bullion coin (the Gold Maple Leaf) at a face value of $50 containing one troy ounce (31.1035 g) of gold—as of May 2011, this coin is worth about $1,500 CAD as bullion.[3] Bullion coins' minting by national governments gives them some numismatic value in addition to their bullion value, as well as certifying their purity.
American Platinum Eagle bullion coinOne 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.
Economic Use
1kg gold bar (ingot)Gold and silver, and sometimes other precious metals, 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
A precious metal that became common is aluminium. Although aluminium is one of the most commonly occurring elements in the Earth's crust, 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.[4] 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.[4] Additionally, the pyramidal top to the Washington Monument is made of 100 ounces of pure aluminium. At the time of the monument's construction, aluminium was as expensive as silver.[5] Over time, however, the price of the metal has dropped; the invention of the Hall-Héroult 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]
