PROBLEM TO BE SOLVED: To easily perform a medal recovery work for a game machine using medals, preventing the medals from reacting with an unfair medal sensing apparatus. SOLUTION: By using a medal A provided with a magnetic material, a recovery work of medals can be performed using a bar magnet, and hence the work can be easily carried out. Further, the magnetic material is located at the center of the medal so that the medal may not react with the unfair medal sensing apparatus. If these medals are used, a weak point in which a work for recovering conventional non-magnetic medals cannot be easily performed can be overcome. In addition, by providing the magnetic material at the center of the medal, the medal can be used in a game machine using medals.
