The red, white, and blue socks that former President George H.W. Bush wore during the ceremonial coin toss at Super Bowl LI in February will be auctioned off by a Roman Catholic diocese in Maine.

Additionally, the Roman Catholic Diocese of Portland said the winner will receive a personalized letter from Bush, according to the Associated Press.

Along with the socks, Bush donated an autographed photograph from the coin flip, all of which is to be auctioned off at a Diocese ball in Portland on Friday.
