• Radial Line Border.  A border entirely of rays, a series of raised lines, which if all lines were extended inward they would cross at the center point. Radial lines rise from a field to form a border element; thus they differ from a reeded rim (which is raised lines on top of the rim). An example of radial line border is on the 1797 U.S. half cent.
