Dan Imler, the vice president of SCP Auctions, may have been destined to specialize in sports memorabilia: He was born into a family of auctioneers and grew up on baseball (a Massachusetts native, he roots for the Red Sox). On Imler’s watch, SCP has handled the April sale of the earliest pair of Michael Jordan game-worn sneakers to come to market ($71,553), the 2007 private sale of a 1909 T206 Honus Wagner baseball card ($2.8 million), and the 2005 auction with Sotheby’s of the original 1935 plaster cast of the Heisman Trophy ($228,000).
