The green card was from the Lightning Poker table that no longer is in play.
The white card was the hotel room key, which has been replaced by a generic Crowne Plaza key.
The "Commerce Casino Players Card" with the picture of the hotel is made of paper.
The back is blank with a magnetic stripe. I've asked the cashiers cage what this was for and they didn't know.
Anyone have a clue? (I found it lying near the cashiers cage)

(the blue chip is/was from a tournament, don't know if its obsolete or not).
