For a few cards, put each in a penny sleeve and a top-loader, tape the top-loader closed (not the card), and sandwich it between pieces of cardboard so it can't bend, then use a bubble mailer. For valuable cards, add a semi-rigid holder, use a rigid box, and buy tracking and insurance — and consider requiring a signature. Never ship a valuable card in a plain envelope. Include the card in a way that resists bending and moisture. For graded slabs, wrap the slab, immobilize it in a box, and insure it. Following these steps prevents the most common (and heartbreaking) shipping damage. When in doubt, over-protect — the extra packaging costs far less than a ruined card.
