This is the question that starts with a wrong assumption, and the assumption costs people money. A graded card does not need a case chosen for it, because the case was chosen for you: the grading company sealed the card inside its own slab, and that seal is the grade. What you can still decide is smaller and more useful than a cavity size.
Quick answer
You cannot case a graded card again. The slab is the case, it is permanently sealed, and putting a second rigid holder around it risks scratching the acrylic you paid to have. What you choose instead is whether to sleeve the slab, where to store it, and whether you wanted the slab look rather than the grade — in which case the right product is a display case for a raw card, like our Pro-Grade Display Slab.
The grade is the seal. Anything you add around a slab protects the plastic, not the card.
What is already decided for you
When a card comes back from a grading company, four things are fixed and not negotiable:
| Element | Who decides it | Can you change it? |
|---|---|---|
| The case itself | The grading company | No — opening it voids the grade |
| The label and the number | The grading company | No — it is printed and sealed with the card |
| The footprint and thickness | The grading company’s tooling | No — every slab is a fixed size per company |
| Whether it fits a binder or a box | Follows from the above | Only by choosing the binder or box |
That last row is the only real decision, and it is a storage decision rather than a case decision. Slabs are larger than raw cards on every side, so a page or a box built for raw cards will not take them. Does a PSA 10 slab fit in a binder answers that one directly.
What you can still add
Three things, in ascending order of usefulness:
- A slab sleeve. A soft sleeve sized for the slab, which protects the acrylic from scuffs and fingerprints. It does nothing for the card, which is already sealed. Worth it if the slab is handled or displayed; pointless if it lives in a box.
- A storage box cut for slabs. The correct answer for a collection of graded cards. Every slab of a given company is the same size, so a box that fits one fits all of them.
- Nothing at all. Genuinely fine for most collections. A slab is already a rigid, closed, acid-free container. The failure mode for graded cards is not damage, it is light and heat.
The thing not to add is a second rigid case. There is no standard product for putting a slab inside another holder, and forcing one on means a hard shell against a hard shell with grit between them. If a slab is scratching, the cause is usually a stack of slabs sliding against each other, and the fix is a box with dividers, not another case.
If what you wanted was the slab look
A large share of people searching for a case for a graded card have not graded anything. They want the object: a rigid, clear, labelled holder that displays a card the way a graded one displays it, without the submission, the queue or the fee.
That is a real product and it is not a fake grade. Our Pro-Grade Display Slab is a two-piece press-fit case, 83 × 130 × 6 mm, with a cavity of 63 × 88 mm for TCG cards or 63.5 × 88.9 mm for sports cards, and a blank label window above the card for your own note. Nothing is pretended: the window is blank, there is no number on it, and the card inside is raw.
Two things to be clear about before buying one. The first is that press-fit means it opens again, which a graded slab does not — that is the whole functional difference, and for a card you want to inspect or photograph it is an advantage. The second is that it is a display object, not a grading substitute: it adds no grade, no authentication and no population figure, and nobody should describe it as if it did.
How to decide, in order
- Is the card already graded? If yes, stop here. Choose a storage box and, if it is handled, a slab sleeve. There is no case to choose.
- Is the card raw but you want the slab look? Then a display case is the right product, and the choice is down to cavity size — 63 × 88 mm for a TCG card, 63.5 × 88.9 mm for a sports card.
- Is the card raw and going to be handled or traded? Skip the display case. A sleeve and a toploader is the pair that survives being posted, and a toploader is what a buyer expects to open.
- Is the card raw and staying put? A press-fit card case, with the card in its sleeve, is the layer that keeps dust and edges out.
Where our own stock sits
We sell graded cards — PSA 10 only, and everything we list graded is a PSA 10, for the reason set out in why we only sell PSA 10. That means our graded stock arrives to you already slabbed, and the question of what to put around it is the one this page has just answered: a box, or nothing.
We also sell the holders for the raw cards you have not graded: a toploader, a penny sleeve, a press-fit case and the display slab. Those are on separate product pages, because they solve different problems. Card case sizes explained converts every dimension we publish.
Frequently asked questions
Can you put a graded card in a card case?
No, not usefully. A graded card is already sealed inside the grading company’s slab, and the seal is the grade. A second rigid holder around a slab is not a standard product and risks scratching the acrylic. What you choose for a graded card is a storage box, or a sleeve for the slab itself.
Does a graded card need any extra protection?
Rarely. The slab is rigid, closed and acid-free, so the card inside is already protected. What slabs are vulnerable to is scuffing on the acrylic and fading from light and heat, so a box with dividers and a shelf out of direct sun do more than any added holder.
What is a display slab, and is it the same as grading?
A display slab is a two-piece press-fit acrylic case for a raw card, with a blank window above the card for your own label. It looks like a graded slab but adds no grade, no authentication and no population figure, and it opens again. It is a display object, not a grading substitute.
Which cavity size do I need for a display slab?
It depends on the card. Ours is 63 x 88 mm for a standard TCG card and 63.5 x 88.9 mm for a sports card. The difference is small but real: sports cards are cut to a slightly different standard, and a TCG cavity on a sports card can catch a corner.
