Somebody spent $1 million for tickets to Coach K's final game against North Carolina

• Legendary Duke head coach Mike Krzyzewski, known as Coach K, is retiring at the end of this season.
• Tickets for his final home game - a grudge match against rival UNC - are selling at a record clip.

Even in an ordinary year, tickets to a Duke vs. UNC game are among the priciest in college basketball.

And this is no ordinary year.

Legendary Duke Blue Devils head coach Mike Krzyzewski - better known to most as Coach K - will retire at the end of the 2021-2022 college basketball season. This year's season-ending matchup against the Blue Devils' bitter rivals, the North Carolina Tar Heels, will mark Krzyzewski's final regular-season game as Duke's head coach - and his final game patrolling the sidelines at historic Cameron Indoor Stadium.

"That'll be a tough ticket [to get]," Krzyzewski said Tuesday during an interview on ACC Network show "Packer and Durham."

That's an understatement. Tickets for the March 5 showdown are selling at a record clip, with prices starting at $6,500 each on StubHub and going for as much as $50,500.

And while those numbers are already astounding, Krzyzewski said that seats for his final showing in Cameron Indoor have gone for far more than that. Four seats to the game sold for a whopping $1 million earlier this year, the all-time winningest coach in college basketball history revealed on the show.

Krzyzewski explained that he and his family have hosted the V Foundation's annual "Wine Celebration" in the Napa Valley for more than a decade. This year, the event raised $12 million for cancer research on behalf of late NC State coach Jim Valvano, and the first auction item was a quartet of tickets to Coach K's final Duke-UNC home game.

A mystery bidder dropped seven figures to secure their spot.

When "Packer and Durham" co-host Mark Packer joked that he still hasn't gotten his tickets for the game and inquired whether Krzyzewski would get him some, the Hall of Fame coach quipped "Where's your million?"

"For one ticket, it's $250,000," Krzyzewski continued. "I can split the four but I'm not cutting the price. In fact, I might add the price. Yours is 300 [thousand]."
