Billets, or ingots (as they sometimes referred to), are not of practical use until they have been formed
into more functional shapes and sizes. While they have already been put in the furnace, they still
require a series of shaping and molding procedures such as hot and cold working, milling and cutting
before they are sold in hardware stores, or used for different applications. The unformed billets,
however, can be used in striking currency such as coins and as reserves, similar to gold bars.
