Robert Kraft has put his Super Bowl LI championship ring up for bid to benefit the All In Challenge.

The winner also will receive a personal visit with Kraft in his Gillette Stadium office, with the New England Patriots sending its private plane to bring to town the new owner of the ring if he or she is not within driving distance.

The All In Challenge aims to be the largest digital fundraiser in history by raising tens of millions of dollars to feed those in need.
