How to Ship Sports Cards Safely

Raw (ungraded) cards should go into a penny sleeve first, then a rigid top-loader or card saver. Never ship a raw card loose in a top-loader with room to slide around — movement during transit is the most common cause of shipping damage.

For a single card, a bubble mailer with the top-loader taped to a piece of cardboard (so it can't slide inside the mailer) is the standard, reliable approach. Avoid regular paper envelopes for anything with real value — they bend.

Graded (slabbed) cards are much more protected, but the plastic holder itself can still crack if the package gets crushed. Wrap the slab in bubble wrap and use a rigid mailer or small box, not a soft envelope.

For higher-value cards, add tracking and consider insurance — most carriers offer it for a small added cost, and it's cheap protection against a lost or damaged package turning into a full loss.

Always take a photo of the card in its holder and the sealed package before you send it. If a buyer disputes a claim about condition or delivery, that photo is your evidence.
