Modern Trading Card Population Growth Complicates Valuation and Liquidity Assessments
Corporate consolidation and record-high grading volumes are expanding the supply of modern collectibles, raising the risk of dilution for high-value portfolios.
The expansion of modern trading card populations is complicating valuation and liquidity assessments, as overproduction and concentrated auction results obscure underlying market supply. High-value portfolios face unique exposure to these shifts, where the physical volume of graded material can dilute the scarcity premiums historically relied upon for capital preservation.
Evidence Behind The Portfolio Decision
Documented valuation, risk and control factors shape the portfolio decision.

The scale of the modern market reflects a tension between institutional consolidation and historical supply limits. Sports trading cards produced from 1980[1] onward were widely overproduced, a supply dynamic detailed in Heritage Auctions' historical guides. This modern era of high-volume production has become highly institutionalized; for instance, Fanatics acquired Topps' trading card and collectibles businesses in 2022,[2] in a transaction valued in the $500 million[2] range, as documented by ESPN. By 2026[2], the volume of modern cards submitted to major authenticators has continued to scale, creating further challenges for valuation and forcing a reassessment of historical rarity models.
The primary mechanism driving modern card valuations is the third-party grading system, which establishes a strict hierarchy of condition. Items certified by Professional Sports Authenticator tend to command higher prices than ungraded counterparts, a trend visible in the PSA Price Guide.[3] However, this premium relies entirely on the scarcity of the assigned grade. Grading volume reached record highs as major authenticators struggled to keep pace with historic demand, an expansion published by The Athletic.[4] This surge in grading activity means that population reports—the public registries showing how many copies of a card exist in each grade—are expanding rapidly. An asset appraised at a high value based on a pristine grade faces dilution risk if subsequent submissions increase the population of identical high-grade cards, lowering the net realizable value of the holding.
What The Evidence Supports
Trading-card values are often discussed through record sales, but professional diligence starts with graded population, issue scarcity, athlete or property concentration, and platform liquidity.

This dilution risk is compounded by the extreme concentration of value around a narrow group of modern athletes and specific card parallels. While high-end modern cards have achieved record-setting public auction results in details compiled by The Athletic, these transactions represent an incredibly thin segment of the market.[4] The vast majority of modern cards do not share this liquidity. A clear distinction exists between an auction estimate, which reflects the competitive bidding of a few passionate bidders, and the net realizable value of a broader card portfolio. If an estate or trust holds a large volume of modern cards, attempting to liquidate them simultaneously can overwhelm the market, depressing prices and exposing the portfolio to severe liquidity friction during a forced sale.
Beyond population risk, the underlying authentication and provenance of the assets introduce additional complexity. In the vintage segment, where cards and memorabilia lack modern league or team certification, third-party verification is essential but complex. The rising demand for game-used gear and equipment has put immense pressure on auction houses to secure third-party stamps of approval, a friction detailed by Sports Collectors Daily.[5] To protect market integrity, professional authenticators like Memorabilia Evaluation and Research Services have demanded strict compliance guidelines and audits of company bidding records, a policy outlined in Sports Collectors Daily.[5] This highlights the operational friction of the asset class: unlike traditional financial instruments, the value of a high-end collectible is entirely dependent on external, subjective opinions of authenticity and condition that remain vulnerable to dispute and revision.
Ultimately, the lack of standardized lending covenants and the thinness of the valuation basis for modern collectibles leaves significant diligence gaps in portfolio management. While a collection may carry a substantial appraisal value, that figure often fails to account for transaction fees, market depth, or the risk of grade inflation. It cannot be assumed that a portfolio of graded cards can serve as stable collateral or provide immediate liquidity. Until authenticators and marketplaces establish transparent, standardized reporting on transaction volumes and population growth rates, these assets remain highly illiquid, concentrated holdings that require independent, purpose-specific valuations rather than relying on retail price guides or isolated auction results.
Evidence limits: the available record leaves these points unresolved: valuation basis is too thin. It does not establish which value can be used for tax, insurance, collateral, succession, or sale decisions.

Pro Sports Memorabilia Authentication Brings ChallengesSource passage
Collectors trust memorabilia authenticators and dealers to get it right. It’s hung in the closet for years. Or packed away in a trunk. Maybe it came from someone who knew someone who knew someone else. Skyrocketing prices for authentic jerseys and equipment in all sports have resulted in a demand from fans who want a piece of something used on the playing field. While pro leagues are now monitoring and in some cases, controlling the distribution of game used memorabilia, there is a tremendous amount of material from years past that has no league or team certification. Pro sports memorabilia authentication was the topic of panel discussions at the recent Premier Collectible Conference in Chicago. Mirroring the demands of a post-Operation Bullpen autograph world, the strong and sustained interest of game worn and equipment collectors has put pressure on auction companies to find a third party to put a stamp of approval on virtually everything they sell. Milwaukee-based Memorabilia Evaluation and Research Services (MEARS) provides detailed investigative work, utilizing a variety of authentication methods before offering an opinion on whether an item is genuine. The widely respected company had been doing work for several auction firms until it recently demanded compliance with a set of strict guidelines and demanded audits of company bidding records.
