PROBLEM TO BE SOLVED: To provide a token for Pachinko slot games, and a method for manufacturing the same.SOLUTION: A token is formed by punching and engraving a stainless steel plate. An oxide layer is formed by an electrolytic reaction or a chemical reaction on the surface, and the surface is coated with a low-conductive colored film obtained by thickening the film thickness of the oxide layer so that the token can be discriminated by a kind with the color of the colored film. The low-conductive colored film is located and polished at the edge of the outer periphery of the token and the edges of projections on the surface of the token to form detection thin film parts with a reduced film thickness. By this structure, current distribution is permitted when a terminal of a contact electric sensor in an automatic supply system is brought into contact with the detection thin film parts, and the presence of the token is detected. |
