Buying a Graded Card: What to Check Before You Pay
Above a few hundred dollars, most cards change hands slabbed, and for good reason: certification removes the two things that cost buyers the most money — fake cards and condition disputes. But a slab is not a blank cheque of trust. Here are the checks worth running before you send the payment.
1. Verify the certification number — always
Every major grader publishes a free online lookup. Type the number from the label into the grader's own site and confirm three things match: the card, the grade, and the year/set. If the listing shows a PSA 10 Charizard but the cert returns a PSA 8 of something else, you've just saved yourself a five-figure mistake. This takes thirty seconds and it is the single highest-value habit in graded buying. Where a listing photo is too blurry to read the cert, ask the seller for a clear one — a legitimate seller will send it without complaint.
2. Read the whole label, not just the number
The big number gets the attention, but the small print changes the value. Watch for qualifiers — abbreviations like OC (off-centre), MK (marks), ST (stain), MC (miscut) — which sit beside the grade and can cut a card's value substantially versus an unqualified grade at the same number. Also distinguish a numeric grade from an "Authentic" or "Authentic – Altered" label: those confirm the card is real but carry no condition grade, and they typically trade below a clean raw copy.
3. Inspect the case itself
Ask for photos of the slab from several angles. You're looking for cracks, deep scratches over the card window, and any sign the case has been opened and resealed — mismatched seams, glue residue, or a lid that sits slightly proud. A cracked case isn't necessarily a dealbreaker (graders will reholder), but it's a price negotiation, and a resealed case is a walk-away. If anything about the slab looks off, read our guide to spotting a fake slab before going further.
4. Check the population before you call it rare
Graders publish population reports showing how many copies exist at each grade. A "rare" PSA 10 with a population of 12,000 is not rare. Population is also why the same numeric grade means different things across eras: a gem-mint vintage card survived decades of handling and poor storage, while modern print quality makes high grades common. Our own model reflects this — the gem premium we apply to a vintage card is several times what we apply to a current-era one, precisely because the scarcity is real in one case and manufactured in the other.
5. Anchor to a value, not to the asking price
The most common way to overpay is to treat the seller's number as the reference point. Look the card up first, note the fair market value and the disciplined buy target, and only then look at listings. On every SplitShot card page above a few hundred dollars we also model what the graded copy is worth versus raw, so you can see whether the premium being asked is in the normal range or well beyond it. If you're weighing a slab against buying raw and sending it in yourself, our grading guide works through that maths from the other side.
6. Buy where you're protected
Prefer sellers with a long, card-specific feedback history, and pay through channels with buyer protection. On eBay, cards above roughly $250 can also route through the Authenticity Guarantee, which adds a physical inspection step — genuinely useful on high-value purchases. Avoid off-platform payments entirely, however good the price looks; that discount is the fee you pay for having no recourse.
When it arrives
Slabs are tough but not indestructible — the corners are where a dropped case cracks. If the card is going to move around at all, a slab guard adds a shock-absorbing shell, and a dedicated graded card storage box keeps a growing slab collection from scratching itself. Keep them out of direct sunlight; our storage guide covers the full setup.
