If you had $1.2 million to burn, what would you buy -- a nice house, a fleet of slick cars, your own island?

How about an unusually small -- and valuable -- baseball card?

That's exactly what collector Brian Seigel did in 2000, when he paid $1.1 million, plus a 15 percent buyer's fee, to acquire the T206 Honus Wagner (PSA 8 NM-MT, to be exact) card. The item isn't only coveted among baseball card aficionados -- it was also the most expensive item purchased on eBay that year.
