The auction for Barry Walner’s 1952 autographed Bowman baseball card of Hall of Famer Mickey Mantle is over, with the winning bidder paying 900,000 times more than Walner originally paid for it.

Purchased for 5 cents by Walner in a pack of baseball cards in 1952, it sold for $45,000 in the Goldin auction that ended on Oct. 10, 2026.
The sale triggered mixed emotions for Walner, who is grateful for the sale but eventually hoped that it would sell for a higher price and feels some sadness that he no longer owns it. But he has been amazed at the incredible journey it sparked for him from the moment he decided to part with it.
“The real change in my life came from everything that happened around the card — the people, the learning, the writing, the laughter and the opportunity to have an entirely new experience at an age (83) when I certainly was not expecting one,” he said.
Initially, Walner, who lives in Sonoma, California, thought he was simply preparing to sell an old baseball card, albeit one with a very early signature of Mantle.
“Instead, the card gave me a new community, strengthened important relationships, turned me into a writer and occasional media personality and allowed me to share the joy of my childhood hobby with hundreds of other people,” he said. “And the card increased dramatically in value. In many ways, so did my life.”
Walner purchased the card in March or April of 1952 and then mailed it to Mantle, asking him to sign it, in care of the New York Yankees, at Yankee Stadium. In late April 1952, Walner received the signed card from Mantle.
Through the years that followed, Walner always believed the signed Mantle card was special, but did not know how special until he connected with a nephew, Justin Hirsch, in Chicago in October 2025.
He learned that Hirsch, the CEO of Jobplex, a global executive recruiting firm, also is the president of Rabbit Hole Auctions, a new vintage sports card and memorabilia auction house.
Walner told Hirsch about the Mantle card, and he was intrigued. Hirsch sent it to PSA, the leading professional grading service for baseball cards and authentications, to be graded.
PSA mailed the card back to him, enclosed in one of its holders, with a grade of 1 (poor), given to cards that have substantial wear, major flaws and/or heavy damage. The grade of the autograph, however, is 8 (near-mint to mint), signifying it is very high-end and authentic.
The reliability of the date of Mantle’s signature was boosted by an analysis done by a fan who provided examples showing the evolution of his autograph every year from 1951 to 1961.
Walner’s 1952 Bowman Mantle card originally was going to be included in the October 2026 offerings of Rabbit Hole Auctions. Walner and Hirsch ultimately decided to instead include it in the auction by Goldin, a larger company that was likely to attract more and higher bidding.
The exciting journey begins
On April 1, Walner and Hirsch were invited to join Mike Moynihan on his “Golden Age of Cardboard” podcast. The episode was titled “The Story Behind the Earliest Known Signed Mickey Mantle Card.”
“I had never appeared on a podcast before and did not know quite what to expect,” Walner said. “Mike’s knowledge of vintage cards and his enthusiasm for the story made the experience enjoyable.”
Walner said that more importantly, Moynihan’s reaction helped him to understand that collectors were not interested only in the autograph and the monetary value of the card.
“They were fascinated by the complete story of an 8-year-old boy buying a pack of cards, mailing the Mantle card to Yankee Stadium and receiving it back signed a few weeks later,” he said.
Walner and Hirsch were also invited to join Leighton Sheldon’s “Trading Card Therapy” podcast on June 30.
“By then, much more research had been completed on the card, and we could explain not just how I obtained the card, but why its timing, autograph and provenance made it significant,” Walner said.
The first phase of Walner’s journey culminated at the National Sports Collectors Convention, the hobby’s largest gathering in the United States, at Donald E. Stephens Convention Center in Rosemont, Illinois, from July 29 to Aug. 2, 2026.
“At the National, I found myself discussing the Mickey Mantle card with serious collectors, dealers, autograph experts, media representatives and people who had spent much of their lives studying Mantle memorabilia,” he said. “Many understood immediately how unusual it was to meet the original owner of a card that had been signed 74 years earlier.”
He participated in several interviews at the National, including one with Diamond Docs, which was producing a documentary about the history of card collecting.

“At the time, I assumed it was simply another enjoyable part of the convention,” Walner said. “I had no idea that the interview would later lead to a film crew coming to Sonoma for the final night of the auction.”
During another interview, one of the interviewers began calling him “Uncle Barry.”
“Of course, I said ‘yes’,” Walner said. “At that point, resistance would have been useless. After that, the name “Uncle Barry” was used during additional online interviews and podcast discussions. People I had never met were referring to me as though I had been attending their family gatherings for years.”
He found it both amusing and touching.
“‘Uncle Barry’ was affectionate and seemed to capture what people enjoyed about my story,” Walner said. “I was not a professional dealer who had discovered the card in a major collection. I was simply the boy who had mailed it to Mickey Mantle, kept it for most of his life and was now telling everyone how it happened.”
Walner had begun sending emails to 15 to 20 family members and close friends who were interested in tracking his experiences and learning more about the card.
“As the story gained momentum, the list began to grow,” he said. “Whenever Bonnie (his wife) or I told another friend about the card, that person usually wanted to be included in the updates. People already receiving the emails also shared the story with others, who then asked to be added.”
What started as a small family and friends correspondence gradually expanded into a group that now numbers approximately 165 people.
“What surprised me most was that many of the people who became interested were not baseball card collectors,” he said. “Some were not even serious baseball fans. They were drawn to the human story: an 8-year-old boy mailing a card to his hero, receiving it back signed and preserving it for 74 years.”
Final night celebration
On the final night of the auction, Walner and his wife were joined by Julia Walner and Matt Walner, their grandchildren; Ben Ruffner and Charlotte Ruffner, their best friends in Sonoma; and Paul Ford and Gail Ford, their Creekside neighbors as well as two of the most ardent followers of the entire journey.
Hirsch joined them through a Zoom call. An iPad displayed his face just below the television screen showing the auction so that he could see and speak with everyone in the living room, giving him a virtual front-row seat.
“In a sense, Justin had become our resident auction expert, commentator and disembodied head,” Walner said.
Morgan Sackett, one of the producers of the upcoming Diamond Docs documentary on card collecting — as well as the winner of three Primetime Emmy Awards — was also there with his crew. They had asked Hirsch if they could come to Walner’s home in Sonoma to film the final evening of the auction.
Sackett and his crew were in San Francisco working on the third season of the Netflix series “A Man on the Inside,” starring Ted Danson. Sackett is an executive producer of the series.
“Their presence made an already unusual night feel even more extraordinary,” Walner said. “The card that had spent decades quietly stored in my home now had cameras waiting to record its departure.”
The auction ended at 7:44 p.m, with a final hammer price of $45,000, representing 21 bids. This is the amount Walner received but with Goldin’s premium of $9,900 added, the purchaser (who has not been identified) paid $54,900.
“The card gave me a year of extraordinary experiences, new friendships, renewed memories and more enjoyment than I could attach to any dollar figure,” Walner said. “None of that disappeared because the bidding stopped below my expectations.”
Although the auction ended, Walner believes that his story with the card is not quite over.
“Morgan and his crew recorded the last evening of my 74-year relationship with the card — my family and friends gathered in our living room, Justin joining us by Zoom, the bids appearing on the television and all of us watching the final 30-minute clock expire,” he said. “I do not know how much of my story will ultimately appear in the completed documentary on the history of card collecting and I understand that the filmmakers will have many stories to tell. But the possibility that my story may become part of a professionally produced film is enormously meaningful to me.”
Walner and and his wife plan to use the proceeds from the sale of the Mantle card to take a vacation together, hold a party for family members and friends who followed the card’s journey and supported him, and purchase a used Tesla, since the one they currently own is primarily his wife’s car.
“I like the balance among the three choices,” Walner said. “The party will allow us to celebrate with the people who shared the journey, the vacation will give Bonnie and me a new set of memories and the Tesla will be something practical that I can enjoy every day.”
