Abstract
Abstract A gambling chip includes a decorative pattern provided on at least one side thereof and on an edge thereof. The pattern is formed by pressure pad marking, i.e., applying an ink pattern to a deformable head and stamping the pattern on the chip. Repeated stamping of different color inks can create different patterns. A layer of varnish is also applied to the chip, either between ink layers or above or below all of the ink layers.
