Gold bars are carried by the banks for the convenience of their customers in the city or elsewhere, and are shipped upon request. Gold bullion as held in banks bears the official stamp of the United States Mint or assay office. This stamp, like that on the coins, is the government attest of the weight and purity of the bars. Besides the official seal, weight, value, and fineness, all bars are stamped with the bar and lot number. They are weighed to the one-hundredth part of an ounce, and are computed by the fineness at $20.671834625 per ounce for pure gold. Small gold bars are made with values ranging from $105 to $600; these are used exclusively for domestic purposes and are not exported. The bars in a certain New York bank's vaults on a certain date, for example, ranged in weight and value from 5.14 ounces and $106.19 value, to 525.6 ounces and $10,849.61 value. The larger bars are used almost exclusively for shipment abroad and the smaller ones for reserve and industrial purposes.
Certain bar charges, as given in the following table, are imposed by the government to cover the cost of making; these vary with the fineness and size of the bar. Bar charges as below are imposed when bars are sold or when a depositor requests, directly or indirectly, special sized bars in payment of a deposit of bullion. Gold bars may be sold only when of standard fineness or higher, for gold coin or gold certificates only, and in lots of not less than $5,000. Silver bars may not be sold except upon special authorization.
