Abdul-Jabbar explained in a post on his blog that he's not selling the items due to any financial trouble. Rather, his decision stems on his ability to impact others.

Primary Income Streams & Multi-Million Contracts

"So, 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," he wrote. "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."

Want to make a bid? You can view the memorabilia available at Goldin Auctions – but it might get pricey. Abdul Jabbar's 1985 championship ring has a minimum bid of $65,000; several other lots are going for tens of thousands of dollars. A handful of items can be had for less than $1,000, though, including plaques, certificates, and sculptures.
