Lionel Carter's collection of about 50,000 cards -- including a near-mint 1910 Ty Cobb, a 1951 Mickey Mantle rookie card and a 1910 Eddie Plank, considered the second-rarest card in baseball -- will receive its first bids Monday at Mastro Auctions in Burr Ridge, Ill., The Chicago Tribune reported Friday.
Carter, 89, decided to sell his collection -- worth as much as $2 million -- after home invaders last year grabbed a handful of the rare cards. Most of the stolen cards were recovered by police.
The cards range in age from the late-1880s to the 1980s, when Carter stopped collecting new cards.
"It all amounted to money," Carter said. "Everyone wanted money. That's not collecting. That's speculating."
The auction ends April 27.
