The invention relates to a valuable object (1) comprising a gold base body (2) surrounded by a protective layer (3). The protective layer (3) comprises at least one readable security code for identification and verification purposes. The invention also relates to a system and method for identifying and verifying a valuable object (1), having at least one readable security code (6) being assigned thereto. The security code (6) of the valuable object (1) is stored in a secure database (4) for identifying and verifying a valuable object (1).

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.

The invention relates to an arrangement (20) to transport a round blank ring (30) made from plastic from a receiving location (35) to an assembly station (90). A every point in time, the orientation and the position of the round blank ring (30) are predefined, at least within a tolerance range. To execute a movement from top to bottom in a height direction (H), it is possible to use a feed device (34) with a motor-driven conveying unit (58). This conveying unit (58) moves one or more round blank rings (30) in a positively guided manner downward in the height direction (H) to a delivery location (36). At every point in time as this is done, the orientation of the round blank ring relative to the height direction (H) is defined, at least within a predefined tolerance range.

A printing method includes programming a 3D printer to print a three-dimensional product, the three-dimensional product being one of a coin, a round, or a bar; selecting a precious metal from one of gold, silver, and copper; providing the 3D printer with the precious metal; directing the 3D printer to create the three-dimensional product with the precious metal; and applying a layer of graphene to a surface of the three-dimensional product; the layer of graphene provides protection to the three-dimensional product.

The management system for substitute currency includes a pattern acquiring device configured to acquire an image of the ground pattern of the substitute currency, a reading device configured to read an ID of the substitute currency, and a control device configured to associate a pattern of the ground pattern with the ID and store the associated pattern and ID in a database. The control device is configured to analyze the image of the ground pattern acquired by the pattern acquiring device to identify the pattern, and determine, based on the database, whether the pattern of the ground pattern of the substitute currency matches the pattern of the ground pattern associated with the ID of the substitute currency obtained from the reading device, thereby to determine authenticity of the substitute currency.

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.
