Hey, don't slam, at least he's making some good coin off of it. Kudos! Unlike back in the days when I collected TMNT, CareBears, My Little Pony, and Transformers sticker books and stickers. As a kid, that was a lot of coin I threw away back then.
I remember playing along with my friends and collecting some holygram hockey cards and traded it back and forth just for fun. Hell, I think someone is holding my million dollar Gretzky card right now.
My best friend has a Wayne Gretzky Rookie card worth huge dollars that he claims he will never part with. I personally never collect any cards. Actually, I collect nothing.. ok, electric guitars, but that's it.
