The pieces are generally seen only as a hobby. But you can buy these things called gold coins, which retain a value equal to its weight in gold, literally! The gold coins are usually available in a variety of sizes, usually 1 ounce or less. There are so many ingots of gold, world coins issued by different countries. The South African rand was first published in 1967. The Krugerrand is available in one, half, quarter and tenth troy ounce. Has a law of 22 carats, which means it is 91. 67% pure gold. More than 46 million ounces of the South African rand were sold until 2008. It was originally invented to help in the sale of gold in South Africa. The American Gold Eagle was first published in 1986. This piece is also available in the same size as the Rand is in. It is 22 carats. A troy ounce Gold Eagle coin has a face value of $ 50, but the gold in the currency is worth more than 18 times that amount. Mexican Gold Libertad was released in 1982. Available in 4 sizes mentioned above and additional troy ounces of the twentieth century. The interesting thing about Liberty is that it is only 22 carats. It is in fact 24 carats, which means that the number is 99. 9% pure gold. Freedom is also available in silver, where the maximum size of a kilo. The Maple Leaf gold coin is the official bullion Canada. Like freedom, which is published in five different sizes. The Royal Canadian Mint set new standard for pure gold leaf maple, while throwing a coin special version in 2007 was 99. 999% pure gold, virtually no base metals. The Mint also produces a large number of pieces of gold 100 kg ingots. Needless to say there were only five. Maple Leaf Gold comes directly from mines in Canada. Austria Philharmonic was released in five sizes, all with 24 carats. The largest size is 1000 parts per troy ounce, equivalent to about 69 pounds. It has a nominal value of 100,000 euros, and 15 coins were minted in 2004. As can be seen clearly, minting coins gold bullion is not limited to large countries. This is something the world because these pieces really help the economy (see Krugerrand). Many of these coins have a face value but end up being worth about $ 1000 without problem, but we must consider the size. A piece 1/20th troy ounce is probably worth 20 times less than a nickel per troy ounce. However, seeing the list price of gold and you will see a similar trend in almost every piece of gold in the world.
