The 1990 Donruss rated rookie reverse negative Juan Gonzalez was and still is one of my favorite cards to find out in the wild. You can buy them all day long but to be rummaging through a 5000ct box of 1990 Donruss and find one is exhilarating. Same for the FF 1989 Fleer Billy Ripken but to me not as satisfying. I hope to one day find one that is good enough to submit and get a PSA 10. It would be a grail for me. There is 80 or so in existence. Anyways collect what you love and love what you collect!
