Gold bullion


A gold bar, also called gold bullion or a 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 400-troy-ounce (12.4 kg or 438.9 ounces) Good Delivery gold bar. The kilobar, which is 1000 grams in mass (32.15 troy ounces), is the bar that is more manageable and is used extensively for trading and investment. 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.

Gold bars are classified into two different types, cast and minted, based on their method of manufacturing. Cast bars are made by pouring molten gold into an ingot mold to shape the gold product. Minted bars are made from gold blanks that have been hand cut to the required dimensions from a flat piece of gold. Markings are almost always applied by presses.

Gold is measured in troy ounces, often simply referred to as ounce when the reference to gold is evident. One troy ounce is equivalent to 31.1034768 grams. Commonly encountered in daily life is the avoirdupois ounce, an Imperial weight in countries still using British weights and measures or United States customary units. The avoirdupois ounce is lighter than a troy ounce; one avoirdupois ounce equals 28.349523125 grams.
