Store graded slabs upright in boxes made for slabs, ideally in individual slab sleeves to prevent scratches. Keep them in a cool, dry place out of direct sunlight, don't stack them loosely, and use UV-protective display cases for slabs you show off. Photograph each slab and record its certification number for insurance.
A graded slab protects the card inside, but the slab itself needs care. Scratches and cracks lower its display appeal and can affect resale.
Everyday storage
- Slab sleeves: soft individual sleeves that stop slabs scratching each other.
- Slab storage boxes: boxes sized for slabs, so they stand upright with little movement.
- Padded cases: for transport to shows or for high-value slabs.
Display
- Slab stands and tabletop holders for single slabs.
- Wall-mounted frames made for slabs.
- Display cases with UV protection to slow fading of ink and holo.
Keep displays out of direct sunlight, which fades cards even through slabs over time.
Environment
- Cool and dry: avoid attics, garages and damp basements.
- Stable temperature: big temperature swings can cause condensation.
- Silica gel packs in storage boxes in humid climates.
Handling
- Hold slabs by the edges to avoid fingerprints and scratches on the face.
- Don’t drop slabs onto hard surfaces.
- Keep them away from pens, keys and coins.
Records and insurance
- Photograph the front and back of each slab.
- Record certification numbers in a spreadsheet with purchase price and current value.
- Check whether your home insurance covers collectibles, or consider a specialist collectibles policy for high-value collections.
Common questions
Can graded slabs get scratched?
Yes. The plastic scratches if slabs rub against each other. Slab sleeves and upright storage prevent most scratches.
Should I store slabs flat or upright?
Upright in a slab box is best. Stacking slabs flat in loose piles leads to scratches and puts weight on the bottom slabs.
Can slabs crack?
They can crack if dropped or crushed. Padded storage boxes and careful handling prevent most damage.
