The PSA 10 Marketplace for Serious Collectors

Where Gem Mint Collectors Compare Notes

PSA 10 cards sit at the top of the grading pyramid, and the collectors who chase them take condition seriously. On Mantel, you'll find the community that tracks population reports, monitors gem rate percentages on new releases, and debates whether that centering is truly 60/40 or just barely holding. Whether you're hunting a PSA 10 Luka Doncic Prizm, a gem mint Mike Trout Update RC, or a flawless Mac Jones rookie — this is where collectors who care about the slab connect.

The PSA 10 premium is real, but it varies wildly across sports and eras. A PSA 10 on a modern Panini Prizm basketball card might carry a 3x premium over a PSA 9, while a PSA 10 on a vintage 1971 Topps hockey card could be 50x or more. Mantel's community helps you understand where the premiums make sense and where you might be overpaying for a half-grade difference.

See What Collectors Are Pulling and Buying

Share your freshly graded returns and see what other collectors are cracking. Follow the conversation around PSA submission results — which Bowman Chrome boxes are producing gem rates above 70%, which Prizm football releases are coming back with tough centering grades, and which hockey products are surprisingly clean. The best intel on grading odds comes from collectors pooling their results.

Live Marketplace Listings in One Feed

Stop searching for PSA 10 cards across a dozen eBay saved searches. Mantel pulls real-time listings from eBay and Fanatics Collect into one feed, so you can browse gem mint inventory across baseball, basketball, football, and hockey without switching tabs. Filter by sport, player, year, or set — and find the PSA 10 you've been hunting.

Connect your eBay seller account to showcase your graded inventory directly to collectors who specifically want slabbed cards.

Comps That Tell the Real Story

Listed prices lie. Comps don't. The gap between a PSA 9 and PSA 10 can be massive, but only if you're looking at what cards are actually selling for. Mantel shows you real completed sales so you can see whether that PSA 10 premium is justified or if the market has softened. Compare across grading companies and grades before you commit.

Track Price Movements Over Time

Population reports change weekly, and every new PSA submission batch can shift the scarcity equation. Mantel's market trends show you how PSA 10 prices move over days, weeks, and months — so you can see when a once-rare gem mint is becoming more common and losing its premium.

Go deeper with advanced analytics that measure real demand versus relisting activity. Know whether a PSA 10 is genuinely scarce and in demand or just being held at inflated prices with no buyers.

SLAM Scores: One Number, Real Market Signal

SLAM scores combine recent sales data, price trajectory, and actual liquidity into a single rating. For PSA 10 cards specifically, a strong SLAM score tells you that collectors are buying at the gem mint price point — not just watching listings expire. Use SLAM scores to compare PSA 10 options across sports and find where real value exists.

What Makes PSA 10 Cards Unique

The Gem Mint Premium — A PSA 10 commands a significant price premium over lower grades because it represents the highest assignable grade. For key rookies like a Justin Herbert Prizm or a Connor McDavid Young Guns, that premium can be substantial and tends to hold during market dips.

Population Scarcity — PSA population reports tell you exactly how many 10s exist for any given card. Low-pop PSA 10s in high-demand categories — think vintage baseball stars or key basketball rookies — carry a scarcity premium that raw or lower-graded copies simply cannot match.

Investment-Grade Confidence — Institutions, high-net-worth collectors, and long-term investors gravitate toward PSA 10s because the grade removes subjectivity. You know exactly what you're getting, and so does every future buyer.

Cross-Sport Comparisons — Gem rates vary dramatically across sports and products. Topps Chrome baseball tends to grade well, while Panini Prizm basketball is notoriously tough on centering. Understanding these differences helps you identify where PSA 10s are genuinely scarce versus just standard.
