Card Protection

Protection is the cheapest money in the hobby and the easiest to get subtly wrong. Nearly every protection mistake is the same mistake: the wrong thickness. A card forced into a holder that is a band too small picks up exactly the corner and edge damage the holder was bought to prevent.

A penny sleeve stops the card rubbing against anything — including the inside of its own holder. It is not protection on its own, it is the layer that makes everything else safe. Use clear ones. Opaque or colored sleeves cause delays at grading, and the sleeve costs the same either way.

A toploader is rigid transport and short-term storage. It is the right answer for a card being mailed, traded, or sat in a box for a season. It is the wrong answer for a grading submission, and we mean that literally: PSA's own shipping guidance lists toploaders alongside tape and sticky notes as things not to send.

A magnetic one-touch holder is display. It costs many times a toploader, it carries UV-blocking additives the manufacturer publishes, and it stands up on a shelf without a separate stand. Buy it for cards you intend to look at, not for cards you intend to ship. A screwdown is the extreme version: nothing moves, ever, and you need a screwdriver to see the card again.

A point is one thousandth of an inch. A standard modern base card is around 20pt bare, and roughly 23pt to 25pt once sleeved, which is why a 35pt holder is the one to stock by the hundred. Everything above that is a band: 55pt for jersey inserts, 75pt for single-patch relics, 100pt and 130pt for thick patch stock, and 180pt and above for booklets, where magnetics and screwdowns take over from toploaders entirely.

Two reference pages here do the deciding for you and are worth bookmarking rather than reading once: the card thickness points chart and toploader sizes explained. Between them they answer the only question that matters at the moment of purchase, which is what fits.

• Clear penny sleeves in the largest count you will realistically use — this is the one item to buy by the thousand
• 35pt toploaders in bulk, because they cover the overwhelming majority of cards
• A small quantity of 55pt and 75pt toploaders for inserts and relics, bought as needed rather than stocked deep
• Resealable team bags sized for loaded holders, which is the step most collections skip
• Magnetic holders only for cards going on display, bought one card at a time

When a card graduates from protection to submission, the format changes again — semi-rigid holders only. That handover is covered in card saver vs toploader, and the supplies themselves in best card savers for PSA.
