A coveted pair of Air Jordans from Michael Jordan's first NBA championship is up for grabs at auction.

Jordan wore the black and red sneakers during Game 4 of the 1991 NBA Finals and later gave them to former Nike executive Sonny Vaccaro, who signed the Chicago Bulls legend to his first shoe deal, according to TMZ Sports.

Vaccaro is selling the sneakers through Goldin Auctions, and they're expected to fetch between $500,000 and $750,000.

"In my six-decade career in basketball, I was fortunate to spend seven years working together with Michael Jordan during my time at Nike, and these Air Jordans represent the moment that he became the most iconic athlete on the planet, as well as the culmination of my career and friendship with Jordan," Vaccaro said in a statement.

"Worn during his very first NBA championship with the Bulls, and the first for Nike with Jordan, the sneakers were a gift from Jordan to commemorate this amazing achievement. The sneakers have remained in my collection for 30 years, and as Jordan's legacy has only grown as the undisputed greatest of all time, I feel that now is the time to share them and their story with a new generation."

Goldin is also auctioning off Jordan's 1985-86 game-worn Air Jordan Dunk Sole sneakers - one of only five pairs known to exist. Bidding on that pair is expected to reach $800,000.
