Gold bar

A gold bar is a common form for bulk storage and transport of gold bullion. Larger varieties of gold bars, produced by casting molten metal into molds, are called ingots. Smaller bars are often created through minting or stamping from rolled gold sheets. Central banks typically hold in their gold reserves the standard 400-troy-ounce (438.9-ounce; 27.4-pound; 12.4-kilogram) Good Delivery gold bar, which is widely traded among bullion dealers. Additionally, the kilobar, weighing 1,000 grams (32.15 troy ounces), and the 100-troy-ounce (109.7-ounce; 6.9-pound; 3.1-kilogram) gold bar are popular for trading and investment because of their more manageable size and weight. These bars carry a minimal premium over the spot price of gold, facilitating small transfers between banks and traders. While most kilobars have a flat appearance, a preference for brick-shaped bars exists among some investors, particularly in Europe.
