An inspection system inspects gaming chips each having a color or a display indicating a value on an outer surface in a state where the gaming chips are stored in a case in which a maximum of the number of gaming chips to be stored is limited, and a radio tag storing gaming chip information is embedded in each of the gaming chips. The gaming chips are stored in the case capable of containing a row of gaming chips stacked in a thickness direction, and the inspection system includes a reading device that reads the radio tag of the gaming chip in the case and acquires gaming chip information of the gaming chip and a determining unit that compares the gaming chip information with a maximum of the number of gaming chips storable in the case and determines an abnormality of the gaming chip in the case when the number of gaming chips obtained from the gaming chip information is different from a maximum of the number of storable gaming chips.

A detection system according to the present invention includes a control device that detects fraud conducted on a game table by using the image analysis result obtained by an image analysis device. In addition, each game token used in this detection system has a multilayer structure having plastic layers with a plurality of different colors stacked on each other, with a colored layer being provided at least intermediately, and white layers or light-colored layers (not illustrated, but may be any layers lighter in color than the colored layer) being stacked on two sides of the intermediate colored layer. As described above, this game token has a multi-layer structure including the colored layer, with the white layers or light-colored layers (not illustrated, but may be any layers lighter in color than the colored layer) being stacked on the two sides of the intermediate colored layer.
