A management system includes a recording device recording an image of a gaming chip and an inspection device determining a type and authenticity of the gaming chip. The gaming chip has a multilayer structure in which both sides of a colored layer are sandwiched between light color layers, surface printing representing a type of the gaming chip is performed on outer sides of the light color layers, and an authenticity recognition mark is printed on the colored layer of an inside of the light color layers by an infrared absorbing material. A visible light camera photographs a visible light image of the surface printing, and an infrared light camera photographs an infrared image of the internal printing. The inspection device determines the type and authenticity of the gaming chip using the visible light image and the infrared image.

An inspection system of a chip includes a reading device and a determining unit. The reading device is configured to count a number of chips stored in a storage case, the chips associated with a table game and including a chip having a radio tag, read the radio tag while the chips are stored in the storage case, and acquire chip information. The determining unit is configured to compare the chip information of the chips in the storage case with a physical number of the chips in the storage case, determine that there is an abnormal chips among the chips stored in the storage case based on a determination that the counted number of the chips does not match a physical number of the chips in the storage case, and output a result associated with an indication of the abnormal chip.

In order to create a long-lasting memento for a musical performance for example, which also has a practical use, a coin or medal is designed with an embossed soundtrack. Furthermore, a method for embossing this coin or medal is proposed.

A machine and method for reducing giveaway material on mint products. The machine may include a conveying assembly for conveying a plurality of mints products to be processed. The machine may also include a processing assembly for processing at least one given mint product at a time, so as to remove an amount of giveaway material from each one of the mint products. The machine may also include a recuperating assembly for recuperating mint products having being processed. The method may include the steps of a) evaluating at least one physical parameter of a given mint product to be processed; b) comparing said at least one physical parameter of the mint product to be processed with a minimum threshold physical parameter in order to determine an attainable range of giveaway material to be removed; c) projecting a targeted amount of giveaway material to be removed from the mint product to be processed depending on the attainable range of giveaway material; and d) removing the targeted amount of giveaway material via at least one surface of the mint product.

When an unfair gaming currency is delivered to a dealer from a player, the currency is detected as unfair. The inspection system for inspecting the gaming currency, in which an RF tag is built, comprises: a gaming currency tray for housing the gaming currencies of the dealer in a casino game; an RF reader for reading the RF tags of the plural gaming currencies housed in the gaming currency tray; plural photosensors for detecting at least the number of the plural gaming currencies housed in the gaming currency tray at a constant time interval or always in a method other than RFID; and an inspection/alarm part for generating alarms when the number of the gaming currencies whose RF tags are read by the RF reader is not equal to the number of the gaming currencies detected by the plural photosensors.
