Gold bars
Gold bars generally range in size from 1/10oz (ounces) to 1kg, but there are bars of up to 500oz available. However, remember that precious metals use troy ounces and that 1 troy ounce equals 31.1 grams.
There are 2 types of gold bars: cast bars and minted bars. Cast bars are produced by pouring molten gold into an ingot mould, while minted gold bars are manufactured via a minting or stamping process. Cast bars are cheaper to produce, but minted bars look better and are generally easier to sell.
