New York Yankees legend Yogi Berra's 1953 World Series player's ring will be offered in an auction at Steiner Sports.
It's valued in excess of $100,000 ahead of the October 23 close date.
The 1953 World Series saw the Yankees win the title for the fifth consecutive time - a feat that has never been repeated.
As the team's star catcher, Berra was one of the main engines behind its success.
Most of Berra's rings were stolen from the Yogi Berra Museum and Learning Center in New Jersey in 2014 and have never been recovered.
This is therefore a very rare opportunity to acquire one.
The auction house describes it as a "Hall of Fame worthy lot", explaining: "This is the only ring that Berra wore for most of his life…
"Yogi wore this ring on his Pinky as he had big strong hands.
"It is impossible to put a value on this ring, but as the MVP leader of the 1953 World Series Championship, this ring may be one of the most valuable World Series Rings ever to hit the market."
A jersey Berra wore during the 1961 season is expected to make more than $45,000.
It's marked "Set 2", indicating it would have been worn late in the season - potentially during the World Series.
As well as being one of the greatest catchers in history, Berra was known for his charming malapropisms, including: "If I didn't wake up I'd still be sleeping", "Ninety percent of this game is half mental" and of course "It ain't over 'til it's over" - a throwaway phrase that has since passed into regular parlance.
