How the Sports Memorabilia Market Changed: A Decade in Review
The last ten years in sports memorabilia came in three acts: a long quiet stretch, a boom that pulled in more new money than the business had ever seen, and a correction that split the market in two. Anyone telling you it was a straight line up is selling something.
2016 to 2019: a dealer's market
For most of the back half of the 2010s this was a slow, relationship-driven business. Prices moved gradually, the buyers were mostly people who had collected for years, and the big money sat in a small number of historic pieces. Authentication had settled into the shape it still has, with PSA and JSA established and Beckett arriving in 2016.
The one structural change in those years came at the top. In 2019 Fanatics bought most of Steiner Sports, one of the biggest names in signed memorabilia, and shut its operation down. That was the first clear signal of what the next decade would look like.
2020 and 2021: the boom
Live sport stopped, people were at home with money they had not planned to have, and an enormous number of them went looking for something to buy. Prices for almost everything rose, grading companies drowned in submissions, and a market that had been aging quietly filled up with buyers in their twenties and thirties.
It was genuinely good for collecting in ways that outlasted the bubble. The infrastructure got better, the information got better, and live breaking went from a niche format to a mainstream way of buying. That's the part of this decade we've got a direct stake in, and we wrote up how the format actually works in how live breaks work.
2022: the peak
The top of the market arrived in a rush. A 1952 Topps Mickey Mantle sold for 12.6 million dollars in August 2022, nearly doubling the previous card record set only a year earlier. Weeks later, the jersey Michael Jordan wore in Game 1 of the 1998 NBA Finals went for 10.1 million.
The clustering tells the story better than any single sale: ten of the twelve most expensive sports cards ever sold changed hands between August 2020 and August 2023. That isn't a market growing steadily. That's a market that ran very hot for about three years.
2023 onward: the correction, and the split
Then modern graded cards came back down. Rookie cards of active stars gave back large chunks of their 2021 prices, and the buyers who had arrived expecting a one-way bet mostly left. What remained was a smaller, more patient set of collectors, which is roughly where the middle of the market sits now.
The top did the opposite. In August 2024 the jersey Babe Ruth wore for the 1932 called shot sold at Heritage for 24.12 million dollars after a bidding war that ran more than six hours, taking the record for the most valuable sports collectible ever and roughly doubling the Mantle card that had held it.
That divergence is the single most important thing to understand about the current market. Unique, historic, provable items kept setting records while the speculative middle cooled. Scarcity that can't be manufactured held its value. Scarcity that depends on a grading label did not.
Who owns the market now
Consolidation is the quiet story of the decade. Fanatics bought Steiner in 2019, took the trading card rights for Major League Baseball, then bought Topps itself in January 2022 for around 500 million dollars. It now also owns PWCC, whose index gets quoted in almost every article about memorabilia returns, along with its own marketplace and live-selling platform.
For collectors that cuts both ways. Buying, grading and selling through one ecosystem is convenient, and a company with that much at stake has real incentive to police authenticity. It also means fewer independent players, and it's worth remembering that when Steiner went, a lot of collectors found their old certificates hard to verify. We covered that and the rest of the authentication picture in who authenticates sports autographs.
What actually changed for signed memorabilia
Cards get the headlines, but the signed side of the market changed in three concrete ways over the decade.
Certification became the default. Ten years ago plenty of signed items traded on a dealer's word. Today an uncertified item from an unknown seller is close to unsellable at any serious price, which is a straightforward improvement.
Witnessed signing replaced opinion. The growth of exclusive athlete contracts means most modern signed product is certified by someone who watched it happen rather than by an expert judging it afterwards. That has made modern items safer and, because supply runs through fewer hands, more expensive.
The buying moved live. Breaks and live streams now sell a meaningful share of what used to move through shops and shows. Whether that suits you is a matter of taste, but it changed where the market happens.
The numbers you shouldn't trust
Market forecasts in this industry are close to worthless. An earlier version of this post quoted a projection that had the market reaching 271 billion dollars by 2034 at a compound growth rate above 22 percent. We're not repeating it, because nothing in the past decade supports that shape, and because the same research firms currently put the present-day market at roughly 28 billion, 35 billion and 51 billion dollars depending on which one you read.
The same caution applies to the return figures that circulate. The widely quoted index tracks graded trading cards rather than signed memorabilia, which we explain in sports memorabilia versus stocks and bonds. And the NFT collectibles that looked like the future in 2021 have not turned out to be much of anything.
What it means if you collect now
The market that came out of this decade is better run and harder to cheat than the one that went into it, and it's no longer a place where you can expect to buy anything and watch it rise. The pieces that held up were the ones with a real story and a supply that can't grow.
For anything you buy at a serious price, run the five checks we use and confirm the certificate on the authenticator's own site first.
