Adding on to what @Toritoribe wrote, it appears that this token came from some type of engraving machine, where in addition to the date of your visit you could have your name added. The name on this token is Kato Michihiko (a man with the family name of Kato).
On the back of the token, the writing begins with 黄金の ('golden'), but I can't make out the final character(s). I'll bet someone else here can, though. It kind of looks like 日向.
