Here's a Bronze Charter Member slot card from the Siena Casino in Reno, NV with Exp. 6/30/07 printed across the top. There were previously cards with NO expiration date plus 12/31/07, 06/30/08 and 12/31/08 expiration dates all on the 11th issue cards with the (I) manufacturer mark. So this is a new addition that was previously not listed in the guides!
