Kareem Abdul-Jabbar has put four of his Los Angeles Lakers world championship rings up for auction.
The former Lakers Hall-of-Fame center has hundreds of items from his memorabilia collection available in the auction, being conducted by Goldin Auctions, with "much of the proceeds" going to his Skyhook Foundation charity to help benefit kids learn about science, technology, engineering and math.
Besides his 1980, 1985, 1987 and 1988 championship rings, Abdul-Jabbar also is auctioning off a game-used signed and inscribed basketball from his final game in 1989. He finished his legendary career with an NBA-record 38,387 points.
