Unfortunately, these Frontier tokens are very common. You see them on ebay frequently for just a couple dollars. In fact, I recently bought an inexpensive chip and the seller threw one of these in free just because he knew I collect some of the Frontier chips. I believe these were used like club points in that you got one everytime you hit a blackjack at the tables and could exchange either 20 or 21 of them, not sure which, for a free room. Most don't show a lot of wear since they weren't used in play or in machines, just handed out to players. They are nice looking though. Hope that helps.
