Card holders and display
Rigid protection for cards that leave the binder: magnetic holders, graded slabs and wall display.
Rigid holders and display cases handle the risks a sleeve can't: bending, crushing and impact. They're sized by card thickness in points, not by area. If a card is going on permanent display, light is the thing to plan around, because the damage accumulates and can't be undone.
Rigid holders resist force, sleeves don't
Sleeves take handling wear. A rigid holder is there to stop the card folding. Once a card is worth enough that a crease would hurt, that's the protection it needs.
You pay for it in access and bulk. Rigid holders are slower to load and take up much more space per card. Standard toploaders come with an extra catch, too: they're made of PVC, which suits transit far better than it suits decades of storage.
Holders are sized in points
One point is 0.001 inch, or 0.0254 mm. Standard TCG cards and modern base sports cards sit between 20 and 35 pt, so 35 pt is the default capacity for regular holders.
Thicker stock climbs fast. Relics, patch cards and heavy premium inserts run well past 35 pt, and holders are made in tiers going into the hundreds of points.
You can get the fit wrong in either direction. A holder much thicker than the card lets it slide around, and a card that slides wears at the corners, producing exactly the whitening you bought the holder to avoid.
If you display cards, plan around light
Display case listings rarely mention this. Light damage follows the reciprocity principle: dim light over a long period does as much damage as bright light over a short one. It accumulates, and it doesn't reverse.
Sunlight is the worst case, being both intense and high in ultraviolet, and fluorescent lighting is comparatively UV-heavy as well. Exhibition guidance for light-sensitive material sits between 50 and 150 lux, which is dimmer than most living rooms.
For anything on permanent display, conservators recommend UV-filtering glazing. Rotating what's on show does more good than any single product you can buy.
Graded slabs
A graded card arrives in its own sealed holder, so you don't have to think about the enclosure. You do still have to think about where it lives. A slab in a sunlit room is still fading, and the same temperature and humidity advice applies to it as to any other card.
Storage and display products for slabs are sized to the slab rather than the card, which is why graded storage is its own category.
Common questions
- Do display cases protect cards from sunlight?
- Only if they are glazed to filter ultraviolet. Ordinary clear acrylic or glass does not stop light damage, which is cumulative and irreversible. Conservators recommend UV-filtering glazing and rotating displayed items rather than leaving them permanently lit.
- What thickness of holder do I need?
- Most standard TCG and modern base sports cards are 20–35 pt, so a 35 pt holder fits. Thicker cards such as relics and patches need a holder rated for their point thickness. A card that rattles around in an oversized holder will wear at the corners.
- What does 35 pt mean?
- Point thickness. One point is 0.001 inch (0.0254 mm), so a 35 pt holder accepts a card up to 0.035 inches thick.
