I came across what I will describe as a token although it had a diameter of only 9/10 of an inch. I can't scan so I will do my best to describe it. It was kind of a grey metal and said Frontier along the top and Hotel Casino under that. In the center was $25 and around the bottom of the coin was Las Vegas. Anybody know how old it might be and what it is worth. I wasn't able to see if the other side was identical because of the container it was in. Would appreciate any ideas.
