State of Slab Fraud 2026: The Data Every Collector and Investor Should See

Graded collectibles have become a genuine asset class. The infrastructure that certifies them has not kept pace with the incentive to defraud them. This report consolidates the publicly reported figures on graded-collectible fraud as of 2026, with attribution, and sets out why the market's next layer of infrastructure is provenance rather than more authentication.

Key Findings

• —PSA reported intercepting more than $200 million in fraudulent or altered collectible value in its 2025 fraud report, its first such report released publicly
• —PSA President Ryan Hoge has been quoted saying that on the extreme end the true figure 'could be well north of a billion dollars'
• —Submissions of the 1952 Topps Mickey Mantle showed a counterfeit rate of approximately 62%
• —Submissions of the 1986 Fleer Michael Jordan rookie showed a counterfeit rate of approximately 25%
• —Counterfeit Pokémon submissions rose approximately 125% year over year; altered Pokémon submissions rose approximately 407%
• —A CGC comic reholder-swap scheme documented by the collector community is believed to affect hundreds of books, with valid certification numbers throughout
• —A December 2025 controversy over PSA buyback and subsequent grade changes was followed by reported resale softening of 10 to 20% on some modern slabs and a roughly 15% shift in submission volume toward Beckett and SGC

1. The Scale of Intercepted Fraud

The $200 million figure is the most-cited number in the category, and it is worth being precise about what it measures. It represents fraudulent or altered value that was caught at submission — items that entered the grading pipeline and were stopped. It is a measure of detection, not of the total attempted.

That distinction is why the executive commentary matters more than the headline. When the president of the largest grading company publicly frames the extreme end as potentially well north of a billion dollars, the operative uncertainty is not whether fraud is material. It is how much of it never reaches a grader at all — because it is circulating in the secondary market, already sealed.

2. Where Counterfeiting Concentrates

Fraud is not distributed evenly. It concentrates on the small set of items where recognition, liquidity, and price all peak simultaneously.

• —1952 Topps Mickey Mantle — approximately 62% of submissions identified as counterfeit
• —1986 Fleer Michael Jordan rookie — approximately 25% of submissions identified as counterfeit
• —Modern Pokémon — counterfeits up approximately 125% year over year, alterations up approximately 407%

The Pokémon alteration figure deserves separate attention. Alteration — trimming, recoloring, surface work, restoration presented as original — is a different problem from counterfeiting. The item is authentic. Its condition is a lie. A quadrupling in one year indicates a professionalizing supply chain, not opportunistic individuals.

“When the majority of submissions of a flagship card are fake, the question is no longer whether fraud is a risk. It is what your verification actually verifies.”

3. Fraud That Survives Certification

The figures above describe fraud caught at the gate. The more structurally serious category is fraud that occurs after certification, where the grader has already done its job correctly and has no further visibility.

The comics market supplied the clearest documented case. In a reholder-based swapping scheme identified by collectors, sealed CGC slabs were opened, the high-grade book removed and replaced with a lesser copy, and the slab submitted for routine reholdering — returning as a factory-sealed case with an authentic label and a valid certification number over the wrong book. Community documentation indicates the affected population may run to hundreds of books.

The card-market equivalents are cert cloning, in which a real certification number is applied to a counterfeit slab, and reseal operations, in which an authentic case is opened and re-glued around a substituted card. All three share one property: the certification lookup returns a clean result.

4. Trust in the Record Itself

In December 2025 a further category of risk entered public discussion. Reporting and collector accounts described a submitter whose cards were graded PSA 9, sold back through buyback at PSA 9 pricing, after which eleven of the same certification numbers reportedly appeared in the registry as PSA 10 without notification.

The dispute itself is unresolved and is presented here as reported. Its market consequences were immediate and measurable: reported resale softening of 10 to 20 percent on some modern slabs, and an estimated 15 percent shift in submission volume toward competing graders. The lesson is structural rather than accusatory — a registry controlled by a single party is a single point of trust, and the market prices that.

5. What the Numbers Have in Common

Read together, these figures describe two distinct failure modes that are frequently conflated:

1. 01Authentication failure — a fake or altered item is presented for grading. Graders address this well, and the $200M interception figure is evidence of the system working.
2. 02Continuity failure — a correctly graded item is separated from its certification after the fact. No grader is designed to address this, and no certification lookup can detect it.

Nearly every high-profile incident of the last two years is a continuity failure, not an authentication failure. The market has been investing heavily in the problem it already solved.

Why This Points to Provenance

Continuity failures require continuity infrastructure: a record tied to the individual physical unit, maintained independently of the grading event, that persists across sales, storage, transport, and services.

That is what SlabProof builds. A tamper-evident NFC seal is bound to a specific slab and paired with a timestamped provenance record — condition at registration, ownership events, transfer history, and any recorded tamper event. Any buyer can tap the seal and read the chain in a browser before a transaction closes. SlabProof does not grade, does not regrade, and is not affiliated with PSA, CGC, Beckett, SGC, or any grading company.

The parallel most collectors find intuitive is the automobile market. A manufacturer certifies a vehicle at production. An independent history report tracks what happens afterward. Both are necessary; neither substitutes for the other. Graded collectibles have had the first for four decades and the second for none of them.
