Gold Coins
From Wikipedia, the free encyclopedia
A Krugerrand gold coin from South AfricaGold coins are one of the oldest forms of money. The first gold coins in history were coined by the Lydian king Croesus in about 560 BC, not long after the first silver coins were minted by king Pheidon of Argos in about 700 BC.
Many factors determine the value of a gold coin, such as its rarity, age, condition and the number originally minted. Gold coins coveted by collectors include the Aureus, Solidus and Spur Ryal.
In 2007 the Canadian Mint produced a 100 kg gold coin with a face value of $1,000,000, though the gold content was worth over $2 million at the time. It measures 50 cm in diameter and is 3 cm thick. It was intended as a one-off to promote a new line of Canadian Gold Maple Leaf coins, but after several interested buyers came forward the mint announced it would manufacture them as ordered and sell them for between $2.5 million and $3 million. As of May 3 2007 there were five confirmed orders. Austria had previously produced a 37 cm diameter 31 kg gold coin worth €100,000 ($153,000).
Obsolete gold coins are primarily collected for numismatic value as collectors items, gold bullion coins today derive their value from the metal (gold) content - and as such are viewed by some investors as a "hedge" against inflation or a store of value. South Africa introduced the Krugerrand in 1967 to cater to this market; this was the reason for its convenient and memorable gold content—exactly one troy ounce. It was the first modern, low premium (i.e. priced only slightly above the bullion value of the gold) bullion gold coin. Bullion coins are also produced in fractions of an ounce – typically half ounce, quarter ounce, and one-tenth ounce.
There are well made counterfeit gold coins in circulation. For example, the Saint-Gaudens Double Eagle omega counterfeit is infamous for its complexity; and has fooled many numismatics experts. It is a high relief business strike, and due to the extensive wear on the die, these coins were not made for many years. For poor counterfeits, a good scale can usually tell if it's counterfeit or not; however, there are many well made counterfeited ancient coins that not only use gold, but the correct amount as well.
An old practice to test whether a gold coin was counterfeit was to bite down on it. Since pure gold is relatively soft any base metals mixed with the gold to lessen its value will also harden the coin, and so make it harder to bite on. The majority of bullion counterfeits (of all types) are rare, and fairly easy to detect when comparing its weight, color and size to an authentic piece as the cost of reproducing any given coin precisely can exceed the market value of the original's.
