Silver bullion bars (ingots) range from 1 oz. to 1,000 oz. sizes. The most commonly traded bars are 10 and 100 oz. in 0.999 fine silver. They are hallmarked (brand stamped) for weight and purity.
Silver bullion bars come in many designs, from simple to elaborate. All are stamped with issuing private mint and the silver fineness and weight.
Private mints, such as Johnson Matthey, Engelhard, A-Mark and the Wall Street Mint, issue silver bullion bars.
