The latter is also known as four nine (9999). To refine and attain pure gold, the smelter has to separate the gold from the other metals (copper, silver,...).

The London gold fixing is the procedure by which the price of gold is determined twice each business day on the London market by the five members of The London Gold Market Fixing Ltd. It is designed to fix a price for settling contracts between members of the London bullion market, but informally the gold fixing provides a recognized rate that is used as a benchmark for pricing the majority of gold products and derivatives throughout the world's markets. The gold fix is conducted in United States dollars (US$), Pound sterling (GBP), and the euro (€) daily at 10.30am and 3pm, London time.

9. What is the gold standard?

A monetary system based on convertibility into gold; paper money backed and interchangeable with gold.

The specification to which a gold bar must conform in order to be acceptable on a certain market or exchange. Good delivery for the London Bullion Market is the internationally accredited good delivery standard.

The LBMA sets and promotes quality standards for gold and silver bullion bars. The minimum acceptable fineness of the Good Delivery Bars is 99.5% for gold bars and 99.9% for silver bars.The London bullion market is an over-the-counter market for wholesale trading of gold and silver.

13. What is the etymology of "bullion"?

Metal in the mass, usually coin, bars, or ingots. The word "bullion" reportedly originates from Claude de Bullion (13th October 1569 – 22nd December 1640), a French aristocrat and politician who served as Minister of Finance under Louis XIII from 1632 to 1640. An alternative theory suggests that it comes from the old French word "bouillon", which meant "boiling" and was the term for a mint or melting house.

14. What is the "carat" measure?

Unit of fineness, scaled from 1 to 24, 24 carat gold (or pure gold) has at least 999 parts pure gold per thousand; 18 carat gold has 750 parts pure gold and 250 parts alloy per thousand. For example, 1 oz gold Kruggerand is 22 carat and minted from gold alloy that is 91.67% pure and copper for the remaining 2 carat.

15. Where does the term "Troy ounce" comes from?

A Troy ounce is the standard weight in which gold is quoted in the international market, weighing 31.1035 grams. It is named after the old French city of Troyes, the location of an annual trading fair in medieval times.

16. What is the premium?

The market value of a coin or product less the intrinsic value (actual value of the precious metal within the coin) of the same represents the premium.

17. What is a restrike coin?

A numismatic item produced from original dies at a later date. Example: the Swiss Vreneli 20 Fr. 1935, re-struck in 1947.

19. Is gold a currency?

Gold has been used throughout history as money.

20. What is White gold?

White gold is a pale precious metal alloy of gold usually with platinum or nickel or palladium.

21. What is a gold allocated account?

An account in which a client's metal is individually identified as his/hers, and physically segregated from all the other gold in the vault.
