NBA Hall of Famer Kareem Abdul-Jabbar has received almost every honor that a basketball player could hope to garner in a career. He’s arguably the most decorated basketball player in the history of the sport. But now the master of the “Sky Hook,” has decided to sell some of his most prized memorabilia.

In total, Abdul-Jabbar put 234 lots of memorabilia — including four of his six NBA championship rings — for sale through Goldin Auctions, with “much of the proceeds” going to his Skyhook Foundation charity that helps kids learn about science, technology, engineering, and math.” The items sold for in excess of $2,947,872.25.

Explaining why has was selling his personal items, Abdul-Jabbar responded, “When it comes to choosing between storing a championship ring or trophy in a room or providing kids with an opportunity to change their lives, the choice is pretty simple: Sell it all.”

According to ESPN, Abdul-Jabbar auctioned off NBA championship rings commemorating the Los Angeles Lakers’ titles in the 1980s, which had starting bids of $60,000 to $65,000, accounted for four of the five highest sales at the auction’s close. Abdul-Jabbar’s 1987 ring sold for the most, at $398,937.50, followed by his ring from 1985 ($343,700). His 1980 and 1988 rings went for $245,500 each.

Also auctioned were three of Abdul-Jabbar’s six MVP trophies — from 1972, 1974 and 1976 — which is going for more than $120,000 each.

“Looking back on what I have done with my life, instead of gazing at the sparkle of jewels or gold plating celebrating something I did a long time ago, I’d rather look into the delighted face of a child holding their first caterpillar and think about what I might be doing for their future. That’s a history that has no price.”
