• and
• the management controller configured to, for each of one or more of the game token coins:
• determine presence of an abnormality based on a history of the location related information of the respective game token coin;
• generate an error signal in response to presence of the determination of the presence of the abnormality;
• and
• identify the constant information of the game token coin that corresponds to the abnormality.
