Hi Robert. I don't know if you need contributions, but I have 100-200 slot cards (player's club cards) from various casinos. Mostly Nevada and California, but some from different US states. They all have my name and player's card number on them. I also have quite a few hotel room keys (card style) if you're interested in those as well. Email me if you want to discuss further, or if what I have is of no interest, that's ok too.
