Every card I sell has to survive an envelope's journey through automated sorting machines, weather, and the occasional careless handler. Over thousands of eBay orders my damage rate has stayed near zero — [X]% by my records — and none of it requires expensive materials. Here's the exact method.
Pick the vehicle by card value
My decision points, in CAD:
- Under C$[20]: plain white envelope (PWE), untracked letter mail — about C$1.50 in postage
- C$[20–75]: bubble mailer with tracking
- Over C$[75]: bubble mailer, tracking, signature on delivery [your threshold]
The thresholds are personal risk math, not rules — set yours based on what a loss would cost you versus the tracking premium (tracked small packet runs several times the letter rate).
The packaging method, step by step
Card into penny sleeve. Sleeved card into 35pt toploader (details in my sleeve guide). Toploader sealed with painter's tape or into a team bag. Then the part that saves cards: sandwich the toploader between the folded halves of a piece of card stock or thin cardboard sized to the envelope, taped so it can't slide around inside. Rigidity plus immobility is the whole game — most mail damage is either bending or the contents shifting into a corner getting crushed.
Tracked vs untracked: the actual risk math
Out of [X] untracked letters I've sent, [X] never arrived — a loss rate of about [X]%. At C$1.50 postage versus C$[X] tracked, tracking on cheap cards costs more than the losses it would prevent. That flips somewhere around the C$[20] mark. One nuance: untracked means you can't win an "item not received" case, so on eBay you're refunding any claimed loss. Price that in — it's part of why sub-$5 cards need such careful fee math.
Do rigid mailers and "do not bend" help?
Rigid mailers: yes, genuinely — for multi-card orders they're my default. "Do not bend" written on the envelope: mostly theater once the letter enters automated processing, but harmless. The cardboard sandwich inside does more than any label outside.
The habit that matters most
Consistency. My packing station has everything within reach, every order ships the same way, and that's why the damage rate stays flat as volume grows. A great method applied sometimes is worse than a good method applied every time.
