I did some internet research on cards and found a company that manufactures cards and they sent me a ton of samples including some casino players club cards. I believe that the company in question is VCT.

Also, I was talking to my sister-in-law who is a VP at a very large 3 party credit/debit card processing company and I found out they own one of the worlds largest producers of plastic cards and she is going to get me samples pretty soon.

I have way too many interests and should narrow them down and concentrate on collecting one type of item.
