A metal is considered to be beautiful 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 a demand or market value. Precious metals in bulk which is known as the gold, and traded commodity markets. Bullion metals may be cast into ingots, or minted into coins. The defining attribute of gold is that is valued by its weight and purity rather of a nominal value as money.
Many nations mint bullion coins. Although nominally issued as legal tender, the value of these currencies face as the currency is far below its value as gold. For instance, Canada mints a gold bullion coin (the Gold Maple Leaf) with a nominal value of $ 50 that contains one ounce troy (31.1035 g) of gold in July 2009, this coin has a value of $ 1,075 as gold. [Edit] Bullion coins' minting by national governments will gives some numismatic value in addition to its gold value, as well as certifying their purity.
1.000 ounces of silver bars
The level of purity varies from issue the subject. 99.9% purity is common. Pure gold coins produced in series in the Canadian Gold Maple Leaf series, ranging up to 99.999% purity. Note that an ingot of 100% pure is not possible, as absolute purity in extracted and refined metals can only be asymptotically approached. Many bullion coins contain a set amount (eg troy ounce) of the marginally-impure alloy. In contrast, the Krugerrand is one of many gold coins and modern history of 22 kt gold crown, with a declared content (Usually one troy ounce) of fine gold "clarifications [edit (define)], with the other component (s) of the alloy making the coin heavier than one ounce in total. More gold coins (for example: British Sovereign) state or the purity or weight of pure gold on the currency, but are recognized and consistent in its composition, [citation needed] and many historically stated a denomination in currency (eg: American Double Eagle).
One of the precious metal coins largest in the world is A $ 10,000 gold coin minted in Australia Nugget, which consists of one kilogram of 99.9% pure gold. There was a small number the largest gold coins, but is not practical 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. [Edit] Austria has minted a coin containing 31 kg of gold (the Vienna Philharmonic coins in 2004 with a nominal value of 100,000 euros). As a stunt to publicize 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 made now in order, but with a substantial premium over the market value of gold.
Gold and silver are seen often as a hedge against inflation and economic recession. Silver coins have become popular among collectors because of its relative accessibility, and unlike most gold and platinum issues which are valued based on markets, money issues are often valued as collectibles, far beyond their real value ingots.

Aluminum
An example of a precious metal that is now common is aluminum. Although Aluminum is one of the most common elements that occur on Earth, was once found to be extremely difficult to extract from its various ores. This made the unwillingness pure aluminum, which had been refined at great cost, more valuable than gold. Aluminum bars were displayed next to the crown jewels of France at the World Exhibition 1855 [citation needed], and the most important guests of Napoleon III, were given aluminum coating, while the less worthy of dining with simple silver. In addition, the top of the pyramid of Washington Monument is made of pure aluminum. At the time of the memorial, aluminum was as expensive as silver. The passage of time without But the price of metal has fallen, the invention of the Hall-Hroult process in 1886 caused the high price of aluminum to close down [citation needed].
Bismuth and tellurium
Bismuth and tellurium are the only two metals that have an abundance of less than 8.10 by mass (g / g) in the crust of the Earth, but it is not now high economic value. [Citation needed]
