Bullion is gold, silver, or other precious metals in the form of bars, ingots, or specialized coins
Two terms often associated with gold bullion are ‘ingots’ and ‘bars’, the most obvious difference being their size. The word ‘ingot’ refers to the molds in which the larger bars are cast, while smaller bars are usually made by minting or stamping. While the classic image is that of vaults full of large, heavy ingots, bullion is available in a variety of sizes and weights. Bullion can be purchased in bars as small as 1g and range through 1 troy ounce, 100g, 500g, 1kg and 12.5kg bars.
