Fragments, scrap struck

Small pieces of coinage metal — fragments and scrap left over from the blanking process — sometimes fall between the dies and are struck. Fragments must be struck on both sides and weigh less than 25 percent of a normal coin's weight to qualify as a struck fragment.

Planchet scrap is generally larger than a fragment, and usually has straight or curved edges as a result of the blanking process.
