Definition

• Collar Gap.  The space between the segments of a segmented collar and the resulting line on the edge of a coin or medal struck from such a collar. The line runs across the edge (perpendicular to the obverse and reverse), and sometimes all three lines may be present – proving it was struck from a trisegmented collar. These lines will be equidistant from each other. Collar gaps are found on some U.S. Mint medals of the 19th century.
