Chipped Collar

Definition: Bits of the collar can chip off, either spontaneously or as the result of impacts. Collar chips are recognizable on the edge of the coin as small, raised defects. Their appearance differs between smooth-edged and reeded issues. In smooth-edged issues, collar chips typically extend down from the rim struck by the hammer die but seldom reach the opposite rim. In reeded issues they are always vertically oriented and often extend from one rim to the other.

Double-struck 1982 cent with die dents and impact scars on both faces. Two large, contiguous collar chips on the edge extend from 11:00 to 2:00.
