A Card Above All Others

In the last 15 years, sports-card collecting has been pulled in two opposite directions. The mainstream fan has lost interest in The Hobby, as it's known. But the hard-core collectors have kept bidding up the most-valuable, rarest memorabilia. And nothing is more valuable than The Card, a small piece of cardboard bearing the likeness of Hall of Famer Honus Wagner that was once bought by Wayne Gretzky for $451,000 and more recently sold for $2.8 million.
