Sure do. A Charmander card that I got in 4th grade for trading my lunch pizza to this one obese rich kid. Still have it till this day (14 years). It's in rough shape, but still one of my treasures. http://i.imgur.com/cKhQ049.jpg
My very first rare was Charizard. At the time I knew nothing about Pokemon and just liked the monsters. Then, when I opened up my second pack, I got another Charizard. I distinctly remember being disappointed that I got the same one twice.
