A gaming
chip, wherein a representation of a type of the gaming
chip is printed on a surface of the gaming
chip, and an authenticity recognition mark is printed more inwardly than the printing of the representation of the type of the gaming chip, wherein the authenticity recognition mark is printed by an
infrared absorbing material. The authenticity recognition mark is irradiated with
infrared rays from a side printed with the representation of the type of the gaming chip printed on the surface of the gaming chip by an
infrared camera to allow an infrared absorbing material printed more inwardly than the printing of the representation of the type of the gaming chip to
record and discriminate the authenticity recognition mark. A
management system comprises an infrared camera generating an
infrared image by photographing the
infrared image indicated by an internal printing of the authenticity recognition mark inside the gaming chip; and an inspection device determining authenticity of the gaming chip based on the
infrared image.
