Protect your cards: sleeves, toploaders and card savers
Which protection to use for each card, from penny sleeves to toploaders, card savers and magnetic holders, and the mistakes that damage cards.
Updated October 21, 2026 · 3 min read
A card loses value the moment a corner softens, an edge whitens or the surface picks up a scratch. Most of that damage happens in the first minutes after a pack is opened, or slowly in a drawer. Good protection costs a few cents per card and keeps every option open: playing, selling or sending it for grading.
The rule: protect valuable cards straight out of the pack
Handle a fresh card by its edges, with clean, dry hands, and slide it into a sleeve right away. Do not stack freshly opened cards face to face or let them slide across a table: that is how surfaces get scratched before they are ever stored.
Which protection for which card?
| Protection | What it is | Use it for |
|---|---|---|
| Penny sleeve | Thin, soft clear sleeve | Every card worth keeping, as the first layer |
| Perfect fit sleeve | Tight inner sleeve | Double-sleeving cards you play with |
| Deck sleeve | Thicker, often opaque back | Playing in tournaments |
| Toploader | Rigid clear holder | Storing and mailing single cards |
| Card saver | Semi-rigid holder | Sending cards to a grader |
| Magnetic holder (one-touch) | Thick two-part case | Displaying high-end cards |
Penny sleeves
The first layer for any card you care about. Choose sleeves sold as acid-free and PVC-free, and slide the card in gently: forcing it in is a common way to dent a corner.
Double sleeves for cards you play
A tight "perfect fit" sleeve under a deck sleeve keeps dust and moisture away from the card and protects its edges when you shuffle. Even so, a card that is played a lot will not stay in mint condition.
Toploaders
A rigid holder for a card already in a penny sleeve. Pick the standard size for your cards: a holder that is too loose lets the card slide and hit the opening. Thicker toploaders exist for jersey and patch cards.
Card savers (semi-rigid holders)
Softer than a toploader, with a wide opening that makes it easy to take the card out. That is why graders like them: PSA asks for semi-rigid holders and does not accept toploaders in submissions, and other graders give their own rules in their shipping guides.
Magnetic holders
Thick cases that close with magnets, good for display. Some models filter UV light. They are heavy and are not what graders ask for, so take the card out before submitting.
Mistakes that damage cards
- Tape on the card or across a holder's opening: removing it can pull the surface or bend the card. PSA's shipping guide bans tape, pull tabs and sticky notes on holders.
- Rubber bands directly around cards: they dent edges. Use them only around a stack of holders between two pieces of cardboard.
- Writing on a sleeve with a card inside: the pen pressure can mark the card.
- Reusing old, dusty or cloudy sleeves: grit scratches the surface.
- Cleaning a card with a product: graders can tell. PSA lists cleaning (N7) among the alterations that keep a card out of a numerical grade.
Our advice
Penny sleeve for everything you keep, toploader for what you store or mail, card saver for what goes to a grader. Then store the cards well: see our guide Storing your collection.
