Condition is a huge part of a card's value, and most damage happens by accident: a card slides out of a stack, gets bent in a drawer or scratched on a table. Good storage is cheap and easy. Here is what collectors use.

1. Penny sleeves for every card you care about

Thin, clear plastic sleeves (often called penny sleeves because they are so cheap) protect the surface from scratches and fingerprints. Put every rare, holo or card you might sell in one. For cards you play with, use thicker game sleeves, and consider an extra inner sleeve for double protection.

2. Top loaders for valuable cards

A top loader is a rigid plastic holder. Slide the card in a penny sleeve first, then into the top loader, so the card cannot move or bend. The standard size fits normal cards. Thicker cards and cards in thick sleeves need a bigger size.

3. Semi rigid holders for grading

If you plan to send a card to a grading company, use a semi rigid holder (often sold as card savers). Grading companies generally prefer them because cards are easier to remove safely than from top loaders.

4. The right binder

Use side loading pocket pages, so cards cannot slide out of the top.
Avoid ring binders for valuable cards: the rings can press dents into the cards closest to them. Zip or bound binders are safer.
Do not overfill pockets and keep the binder standing upright or lying flat, never squeezed between heavy objects.

5. Boxes for bulk

Common cards can go in cardboard storage boxes made for trading cards. Keep them upright and snug, not loose, and never use rubber bands: they dent and bend the cards on the outside of the stack.

6. Watch light, heat and humidity

Keep cards out of direct sunlight, which fades colors over time.
Avoid attics, basements and garages where temperature and humidity change a lot.
Humidity can make cards curl. A few silica gel packets in a closed box help keep moisture out.

7. Graded cards and sealed product

Graded cards are already protected in hard cases, but they can still scratch or crack. Store them upright in a slab box or with protective sleeves. Keep sealed packs and boxes away from sunlight and pressure, since damaged packaging lowers their value.
