Why this matters more than people think
A PSA 10 rookie card can be worth thousands of dollars. Wherever there's real money, there are people trying to fake it — and counterfeit slabs have gotten noticeably better in recent years. The good news: a fake is almost always detectable if you know what to actually check.
Start with the cert number — but don't stop there
Every legitimate graded card has a certification number, and you should always look it up directly on the grading company's own site (psacard.com/cert for PSA, for example) before trusting a listing's photos alone.
Here's the part most guides skip: a cert number check alone isn't foolproof. Scammers have been known to reuse a real, valid cert number on a completely fake holder — the lookup returns real data, but the physical slab in front of you is counterfeit. An even sneakier version: cracking open a genuine slab and re-sealing a different (often lower-grade or outright fake) card inside the real label.
So the real move is: look up the cert, and compare what comes back against the physical card in your hands — not just the grade and player name, but the actual card photos when the grading company provides them. If the cert page shows a card with different centering, different print dots, or visible differences from what you're holding, that's your red flag, even if the cert number itself checks out.
What a real slab looks and feels like
- The plastic itself — genuine PSA holders have a light frosted quality, not perfectly glass-clear. BGS holders are noticeably thick. If a case feels unusually light, glossy, brittle, or slightly flexes in your hand, that's worth a second look.
- The label printing — real labels have crisp, evenly-spaced text and consistent, correct-shade coloring. Blurry text, slightly-off fonts, or misaligned spacing are common tells on a counterfeit.
- The seal — authentic slabs are sealed through a tamper-evident process. If you see edge "frosting," micro-cracks, any flex along the seam, or anything that looks like it's ever been popped open and reglued, don't buy it.
Trust the source as much as the slab
Even a careful physical inspection has limits — which is exactly why buying from a vetted dealer matters as much as checking the card itself. A dealer with a real reputation to protect has no incentive to sell you a fake; an anonymous listing on a general marketplace does not carry that same accountability.
If a price looks meaningfully below what the same card typically sells for, that's worth extra scrutiny, not extra excitement.
The short version
- Look up the cert number on the grading company's own site
- Compare the cert page's card details and photos against the physical card you have
- Check the plastic, the label printing, and the seal for anything that looks off
- Buy from dealers who've actually been vetted, not just whoever has the lowest price
Every dealer on Strictly Graded goes through manual review before they're allowed to list — it's not a substitute for checking the card yourself, but it's one more layer between you and a bad purchase.
