When a counterfeiter prepared his dies, he could either engrave them himself, in a style easily to be distinguished from official mint issues, or he could use a genuine, mint-issued host coin. He would then impress this design into a piece of piece of metal and affix it to the iron die-shaft. This object may represent a counterfeiter's first attempt, a practice strike in lead, as lead is generally too soft a metal for striking coins.
