From Booklist
Perhaps the most volatile of all collectible markets is sports trading cards. Once upon a time, the key factors in determining card value were rarity and the stature of the player presented. So a 20-year-old Hank Aaron card was worth a fistful of cash and could be expected to rise in value. To some degree, that principle still holds true, but those old, relatively rare cards won't support the influx of new hobbyists and new card companies. So the market has gone from genteel antiquing to something paralleling the cutthroat world of soybean futures. Green, a veteran and knowledgeable cardmeister, explores the ins and outs of today's marketplace. The trick, as in any speculative venture, is to know when to sell. A 1977 Jack Clark baseball card, for example, is worth $3 today, but as Clark's dimming star continues to fade, it could drop all the way to a nickel. Sell now. In addition to offering good advice, Green has plenty of opinions on athletes of all stripes, and he loves to share them. He's funny, too, and sure to offer collectors a new perspective on their hobby. Wes Lukowsky
