A timeless moment from Michael Jordan’s historic basketball career has made its way to auction.

Let’s flashback to Game 5 of the 1997 NBA Finals. The Chicago Bulls were going head-to-head against the Utah Jazz. Jordan was seemingly sick with what many assumed was the flu. It was later revealed to be food poisoning, according to Sporting News.

Nonetheless, Jordan wasn’t willing to let his symptoms stop him from performing at his best. With 38 points, 7 rebounds, and 5 assists in 44 minutes, Jordan played a major part in The Bulls’ Game 5 victory.

“I almost played myself into passing out,” Jordan said, according to ABC 7 Chicago. “I came in and I was almost dehydrated and it was all just to win a basketball game. I couldn’t breathe. My energy level was really low. My mouth was really dry. They started giving me Gatorade and I thought about an IV.”

Over 20 years later, the exact sneakers Jordan wore during that game sold for $1.38 million on Goldin, a leading collectibles marketplace, ESPN reports.

The shoes were first given to Utah Jazz ball boy Preston Truman. He later cashed in $104,765 after selling the them through Grey Flannel Auctions 15 years later. In the years since their initial sale, the shoes’ value has risen 1,200%.

“To me, the ‘Flu Game’ is the most iconic game of Michael Jordan‘s career, and that’s what everyone refers to when they talk about toughing it out and rising to the occasion under difficult circumstances,” Ken Goldin, founder and executive chairman of Goldin, said according to Sports Illustrated. “To me, these are the most important and most valuable pair of sneakers that will ever be sold.”
