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.
