A gold bar, also called gold bullion or gold ingot, is a quantity of refined metallic gold of any shape that is made by a bar producer meeting standard conditions of manufacture, labeling, and record keeping. Larger gold bars that are produced by pouring the molten metal into molds are called ingots. Smaller bars may be manufactured by minting or stamping from appropriately rolled gold sheets. The standard gold bar held as gold reserves by central banks and traded among bullion dealers is the Шаблон:Convert Good Delivery gold bar. The kilobar, which is Шаблон:Convert in mass, and a 100 troy ounce gold bar are the bars that are more manageable and are used extensively for trading and investment.[1] The premium on these bars when traded is very low over the spot value of the gold, making it ideal for small transfers between banks and traders. Most kilobars are flat, although some investors, particularly in Europe, prefer the brick shape.[2]
Types
Based upon how they are manufactured, gold bars are categorized as having been cast or minted, with both differing in their appearance and price.Шаблон:Ref Cast bars are created in a similar method to that of ingots, whereby molten gold is poured into a bar-shaped mold and left to solidify. This process often leads to malformed bars with uneven surfaces which, although imperfect, make each bar unique and easier to identify. Cast bars are also cheaper than minted bars, because they are quicker to produce and require less handling.
Minted bars are made from gold blanks that have been cut to a required dimension from a flat piece of gold. These are identified by having smooth and even surfaces.
Security features
To prevent bars from being counterfeited or stolen, manufacturers have developed ways to verify genuine bars, with the most common way being to brand bars with registered serial numbers or providing a certificate of authenticity. In a recent trend, many refineries would stamp serial numbers even on the smallest bars, and the number on the bar should match the number on its accompanying certificate.[3]
In contrast to cast bars (which are often handled directly), minted bars are generally sealed in protective packaging or tamper-evident technology to prevent tampering and keep them from becoming damaged. A hologram security feature known as a Kinegram can also be embossed directly on a gold bar. Bars that contain these are called Kinebars.[4]

Standard bar weight units
Gold is measured in troy ounces, often simply referred to as ounces when the reference to gold is evident. Шаблон:Convert. The troy ounce is heavier than the avoirdupois ounce, a commonly used unit for measuring weight in the United States customary system. Шаблон:Convert.[5]
The standard gold bar held and traded internationally by central banks and bullion dealers is the Good Delivery bar with a Шаблон:Cvt nominal weight. However, its precise gold content is permitted to vary between Шаблон:Cvt and Шаблон:Cvt. The minimum purity required is 99.5% gold. These bars must be stored in recognized and secure gold bullion vaults to maintain their quality status of Good Delivery. The recorded provenance of this bar assures integrity and maximum resale value.[6]

Manufacturers
Largest gold bar
The world's largest gold bar stands at Шаблон:Cvt, measuring at the base Шаблон:Cvt and Шаблон:Cvt high with 5 degree draft angle (equal to Шаблон:Cvt). It was manufactured by the Mitsubishi Materials Corporation, a subsidiary of Mitsubishi. It went on display at the Toi Gold Museum on 11 July 2005. Its gold content was valued in 2005 at 400 million yen (approximately US$3,684,000 at the time).[21][22][23] Шаблон:As of, it is worth approximately US$15.1Шаблон:Nbsmillion.[24]
