I'm wondering what some of you consider a "different" card. Listed below are what I look for:

A change on the back of the card; new phone #, new layout, different manufacturer (PPC, etc.), with or without signature line, etc.

Raised or flat lettering for the player's name and account #.

Different color ink for the player's name and account number.

Cards with no name or account #.

Regular cards that use a clever phrase for the player's name to indicate that the card is a temporary card. Such as "New York New York" on a card in place of the player's name.

What am I missing? It would really be interesting to hear what other slot card collectors look for.
