Todd - MOST (but not ALL) collectors, collect on the basis of the card itself, as it comes from the manufacturer. Some collectors even insist that the card be blank in order for it to be added to their collection. I don't know of any card collectors that care anything about whose name, or how many names and/or account numbers, are on the card. The exception to this is Harrah's cards. There are collectors out there who insist on having one card from each of the Harrah's casinos, with that casino's 3-digit prefix (ie, 104 for Las Vegas, 107 for Cherokee, NC, 157 for Atlantic City, etc.) To paraphrase Pat & Steve's 3rd Edition price guide (page 5, para 2) "Anything that a casino prints on a card is considered "post-manufacturer" and as a rule does not affect the price of the card. Any exceptions to this rule are printed in the book." Availability and condition are the 2 major factors that determine the price of a card. I hope this has answered your questions. Dave
