The trust gap
The Red Flag Library: 34 fraud patterns documented from FBI bulletins, court filings, and authenticator advisories.
The FBI estimates 50–70% of autographed sports memorabilia in the secondary market is fake. Beckett Authentication Services reports approximately 50% of items submitted to them are inauthentic. The Red Flag Library catalogs the patterns — what the fraud looks like, how to identify it, and what to do.
Sample patterns
- Secretarial signatures on Elvis Presley items
high · autographs
- Babe Ruth single-signed baseballs with restitched panels
high · autographs
- Forged or altered PSA/DNA letters of authenticity

- Trimmed cards graded PSA 9 / BGS 9

- 1980s and 1990s Topps reprints sold as originals

Quarterly market reports
8 quarterly market pulse reports — written like a research note, not a marketing post.
Every quarter, we publish a market pulse covering the eight tracked categories. Each report documents tracked sales, median price movement, structural trends, and what we are watching into the next quarter.
Q1 2026 Market Pulse: A Year of Quiet Strength in Memorabilia
Tracked sales across eight memorabilia categories during the first quarter of 2026. Trading cards remained dominant; political/historical documents posted the steepest year-over-year gain; movie-prop sales softened on supply, not demand.
Read report Q4 2025Q4 2025 Market Pulse: The Year Modern Caught Vintage
Q4 2025 sealed the year in which modern-era memorabilia tracked sales caught and briefly passed vintage-era tracked sales for the first time in the recorded series. The shift was not driven by single record-setting outliers — it was the mid-tier.
Read report Q3 2025Q3 2025 Market Pulse: Authentication Bottleneck Becomes the Story
Q3 2025 saw $144.6M in tracked sales — solid, sequential growth — but the operative story was the widening authentication-service backlog. PSA, BGS, and SGC all extended turnaround times. Items in queue are not items on auction.
Read report Q2 2025Q2 2025 Market Pulse: Documented Provenance Becomes the Premium
Q2 2025 was the quarter the market re-priced provenance documentation. Items with verifiable chain-of-custody — auction-house archives, museum records, estate trust documents — pulled away from otherwise-comparable items lacking that trail. The spread is now 30–60%.
Read report Q1 2025Q1 2025 Market Pulse: A Stable Start After Two Hard Years
Q1 2025 was the first quarter that did not require a 'compared to a difficult prior period' caveat. Tracked sales held above $125M, modern-cards recovered to within striking distance of 2021 levels, and the foundational comps stabilized.
Read report Q4 2024Q4 2024 Market Pulse: The Year of the Comeback
Q4 2024 sealed the year of recovery. After 2023's broad correction, 2024 closed at $524.8M in tracked sales — up from $487.2M in 2023. Modern football cards, movie props, and political/historical documents led the recovery.
Read reportThe methodology
Every comp is selected for documentary completeness, source independence, and category relevance.
The Field Index is editorial, not paid. Comps are included because the sale was publicly documented by an auction house, verifiable by third-party authentication, and referenced in trade-press reporting. We do not accept consideration in any form.
- Documentary completeness. Every comp documents venue, lot, date, authentication, estimate range, and at least one third-party source.
- Source independence. Every comp cites at least one source independent of the seller — trade press, grading service, government archive.
- Category relevance. Comps cover the price band collectors actually encounter, not only record-setting outliers.
- Editorial, not paid. Inclusion is decided by the Memorabilia.co Editors. Auction houses and dealers cannot pay for a listing.
- Quarterly refresh. New sales are added each quarter alongside the market-pulse report. The complete dataset is republished every January.
Sources we cite
The auction houses, dealers, and graders behind the data.
Field Index comps are sourced exclusively from auction houses and dealers with published catalogs, third-party authentication, and accountable corporate operations. We do not include marketplace listings without provenance documentation.

Common questions
What collectors ask about the Field Index.
The straight answers on what's in here, how it's sourced, and what it isn't.
Is the Field Index actually free?
Yes. No paywall, no signup, no upsell. Every comp, every red-flag pattern, every quarterly report is freely accessible on the web. Memorabilia.co generates revenue through partnerships with authentication services, auction houses, and insurance providers — not by gating the reference data collectors need.
How is this different from WorthPoint or PSA Auction Prices Realized?
WorthPoint and PSA APR are excellent but single-category, subscription-gated, and built around their own commercial relationships. The Field Index is multi-category (eight memorabilia segments), free, and editorially independent. We cite both PSA APR and WorthPoint as sources when relevant.
Why don't you include eBay sold listings?
eBay sold listings are a useful indicator for ungraded items at the low end, but the noise floor is structurally unfit for a reliable comparable-analysis dataset. The Field Index includes eBay sold listings only when the seller is a recognized authenticator or auction house with documented chain-of-custody.
Can I submit a sale to be included?
Yes. If you are an auction house, dealer, or institution with a documented sale that meets our inclusion criteria (publicly catalogued, third-party authentication, source-citable), we welcome submissions. Use the contact form. Editorial decisions are not subject to payment or sponsorship.
How often is the Field Index updated?
We publish new sales quarterly, alongside the market-pulse report. Significant single sales (above $5M or category record-setters) are added within 30 days of public reporting. The complete dataset is republished in January each year.
Are the figures exact?
Figures reflect publicly reported hammer + buyer's premium as of the source-cited date. They may differ slightly from auction-house internal records. Treat them as directionally accurate for comparable-sale benchmarking; verify with the auction house directly before relying on a single comp for valuation, insurance, or sale decisions.
