He seems like a nice guy, but this book is for someone much more into the hobby than I am. Shortly after I quit collecting, card companies began making a ridiculously huge variety of cards that were created to be rarities, and apparently there are people who value this stuff. When I was a kid, there was a set of cards and you bought packs at the store and tried to get as many as you could. You didn't have to pay hundreds and even thousands of dollars to get a card that was created unique to make it valuable. I think it ruined the hobby. The book's detailed description of dealing for cards got very dry.
