Muhammad Ali's Gloves

Landmarks in Muhammad Ali's career have led to major sales for SCP Auctions. The Kentucky native won his first heavyweight championship on February 25, 1964, when he was still fighting as Cassius Clay. On March 8, 1971, Ali fought Joe Frazier for the first time in what was billed as The Fight of the Century at Madison Square Garden. Ali lost the second fight, but the gloves he wore while fighting Smokin' Joe and the gloves he wore during his first championship match both sold in 2012 for $385,848, a nifty payday that didn't ultimately belong to the fighter. The seller? The estate of Angelo Dundee, Ali's longtime trainer.

"The provenance of those gloves was absolutely ideal," Imler says.
