How to Protect Trading Cards: Sleeves, Toploaders, Binders, Boxes

Match the protection to how you use the card. Sleeve every card you play, and keep all sleeves in a deck identical. Put a valuable single in a penny sleeve, then a rigid toploader. Store a collection you want to browse in PVC-free 9-pocket pages, and keep bulk in cardboard storage boxes somewhere cool, dry and out of direct sunlight.

Each step below has its own page with sizes and product details. Start with the one that matches the cards in front of you.

The four kinds of protection

Sleeves for every card you play

Shuffling wears card edges. A deck sleeve covers the card while you play, and Konami’s rulebook adds a fairness reason: if you use sleeves, they all have to be the same so your cards are not marked. Sleeve sizes differ by game. Sleeve makers list Pokemon, Lorcana and Flesh and Blood as standard-size cards, while Yu-Gi-Oh! cards are smaller; card sleeve sizes has the measurements.

Toploaders for the cards that matter

A toploader is a rigid plastic holder. BCW’s standard 3 x 4 inch toploader fits cards up to 35 points thick. Slide the card into a thin penny sleeve first so it does not scratch against the toploader’s inside. Our page on sleeves and toploaders covers thicker cards and the semi-rigid holders grading companies ask for.

Binders and boxes for a collection

Binder pages keep cards flat and on view. Ultra PRO describes its premium 9-pocket pages as non-PVC, acid-free polypropylene with side-loading pockets that help stop cards falling out. Read trading card binders for page types and capacity. For hundreds of commons, cardboard count boxes hold far more per shelf; see trading card storage boxes.

Sleeves inside a binder

You can combine layers. A card in a deck sleeve can go into a binder page made for sleeved cards: Ultra PRO rates its 9-pocket zippered binder at 180 cards in deck sleeves, and Dragon Shield gives separate single- and double-sleeved capacities for its Zipster binder. Check the rating before you buy, because a pocket sized for bare cards will be too tight for sleeved ones.

Where to keep them

The Library of Congress gives storage advice for photographs, which are paper-based like cards. It recommends a relatively dry (30 to 50 percent relative humidity), cool (70°F or below) and stable environment, and says to avoid attics, basements, and spots near vents, fireplaces, radiators or exterior walls. It notes that light damage is cumulative and that sunlight and ultraviolet light are especially damaging.

In practice that means a closet shelf in a room you live in, boxes off the floor, and binders out of sunny windows.

Protection by game

The game decides the sleeve size and how many cards a deck box has to hold. Deck sizes come from each publisher’s rules; sleeve sizes from the sleeve makers.

As a collection grows

Here is how the protection changes as a collection grows.

1. The first deck. One pack of matching sleeves and a deck box. A Pokemon Elite Trainer Box already includes 65 sleeves and a storage box.
2. The first booster box. Hundreds of new cards. Sleeve the ones you play, put the best in a binder, and start a count box for the rest. A Pokemon booster box alone produces 360 game cards.
3. The first valuable card. A penny sleeve and toploader, kept upright in a box out of the light.
4. A card worth proving. A semi-rigid holder and a grading submission.

At every stage the same storage rules apply: cool, dry, stable and dark.

When you play

Two accessories travel with a deck: a deck box sized for your sleeved cards, and a playmat that keeps cards off a rough or damp table. And if a card is valuable enough to grade, how card grading works explains what graders such as PSA and CGC look at.
