Jerry Kramer's Super Bowl 1 ring, described as "the most significant NFL Championship ring ever offered at auction", will lead a Heritage Auctions sale next month.
The auction will feature memorabilia spanning the entire career of the former Green Bay Packers offensive lineman, who was an integral member of Vince Lombardi's legendary championship-winning team throughout the 1960s.
Kramer is a five-time NFL champion and two-time Super Bowl winner, voted as a member of the NFL's 50th anniversary team in 1969. "It was nice to be a part of that company," he said. "I was the only guard selected in the first 50 years."
"Kramer is widely considered the greatest player lacking Hall of Fame enshrinement," said Chris Nerat, Sports Consignment Director at Heritage Auctions. "He's the sturdy foundation of the greatest era of dominance in NFL history, the epitome of the hard-nosed, take-no-prisoners Lombardi ethic."
The Green Bay Packers claimed victory against the Kansas City Chiefs during the first-ever Super Bowl game in 1967, and Kramer's personal collection includes both his game-worn jersey from the match, and his Championship ring, which is expected to sell for more than $100,000.
Other accolades offered include Kramer's 1962 NFL Championship wristwatch, his 1965 NFL Championship ring, and his 1975 Green Bay Packers Hall of Fame presentational ring.
The sale will also feature everything from signed team footballs and match programmes to game-worn jerseys, helmets and playing contracts. "There was an awful lot of stuff in there that I'd forgotten about," said Kramer, reflecting on his collection which will be sold to establish a trust fund for his grandchildren.
The Heritage Platinum Night Sports Auction takes place in New York on February 20.
