Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of a gaming coin shown as an embodiment of the present invention. In FIG. 1, a gaming coin 1 is formed in a substantially transparent or semitransparent (light semitransparent) disk shape having a predetermined size using tempered glass, and a coin identification device 2 is provided inside. Is buried. The coin identification device 2 uses an IC chip that oscillates a signal of a predetermined frequency, a light emitting device that emits an optical signal, and the like, and each signal is different for each game shop.

FIG. 2 is a process chart showing an example of how to make the game coin 1. Explaining with this process diagram, this game coin 1 is made through the following processes A to E.
First, in step A, finely crushed glass pieces are prepared as a raw material, which is put into a melting furnace. In the process B, the raw materials put into the melting furnace are treated with about 1200 to 1400.
It is heated to ℃ and transferred to the work furnace for about 10 hours. At this time, by utilizing the property that the poor quality glass component floats up, only the good quality glass component is moved into the working furnace and kept at 800 to 1000 ° C. in the working furnace. Process C
Then, the molten glass for one gaming coin is slowly flowed out through the round hole provided at the bottom of the work furnace.
At this time, the coin identification device 2 is placed in the molten glass.
And then embed. In step D, the glass in which the coin identification device 2 is embedded is moved onto the mold of the press machine and is crushed by the press machine to mold the still soft glass into a disk shape. In step E, the disk-shaped glass is heated again to near the softening point and then rapidly cooled. As a result, the surface solidifies first and shrinks internally as cooling progresses, so the solidification ends with compressive stress on the surface and tensile stress remaining inside, and quenching is performed to form tempered glass. It As a result, the gaming coin 1 shown in FIG. 1 is completed.
