Patriots owner Robert Kraft — who won over NYC fans when he donated 300,000 masks to city frontline workers — has put up one of his Super Bowl rings for a charity auction.

The jewelry from Super Bowl LI in 2017 has already hit more than $1 million in bidding, and the auction for the ring still has over a week to go.

Kraft put up the bauble as part of Fanatics mogul Michael Rubin’s “All-In Challenge,” for which celebs and VIPs are putting up prized possessions for bidding or raffles. The initiative has raised more than $41 million in a month for hunger charities.

Over 700,000 people have so far bid on lots that include a private putting lesson with Tiger Woods, a flight on Drake’s private plane, and — thanks to Chris Pratt — the chance to be eaten by a dinosaur in a “Jurassic World” sequel. Leo DiCaprio, Gwyneth Paltrow and Pearl Jam have also participated.

Rubin told us that the night he hatched the challenge, his first four phone calls were to Kraft, rapper Meek Mill, movie star Kevin Hart and NBA Commissioner Adam Silver.

But of all the starry lots available, self-made Rubin said that if he were still a beginning entrepreneur, “I’d be more excited to shadow the CEOs of Walmart, Microsoft, Goldman Sachs — there are several auctions where you can actually pitch your business ideas.”

A raffle to pitch Goldman CEO David Solomon starts at $10, as does a mentoring session with Microsoft’s Satya Nadella and shadowing Walmart’s Doug McMillion. Inventive types can also separately bid on pitching Walmart execs their business ideas.
