Short answer
Sandwich any valuable raw card or slab between rigid boards inside a bubble mailer for cards under $250, or between thicker padding inside a small box above. Insure with signature confirmation above $500. Document the package contents with photos before sealing.
Shipping is where many sellers lose money in collectibles. Damage-in-transit and lost shipments are both preventable with the right packaging and the right service.
The sandwich method (raw cards under $250)
- Card in a penny sleeve.
- Penny sleeve in a top loader.
- Top loader sealed with painter's tape (not packing tape — adhesive can damage on extraction).
- Top loader between two rigid boards (cardboard backers).
- Whole sandwich in a bubble mailer.
- Wrap mailer in a plastic bag if weather is wet.
The box method (slabs and high-value)
- Slab or graded item in original protective sleeve.
- Foam wrap or bubble around it.
- Centered in a small corrugated box with rigid padding on all six sides.
- Box weighs ~1 lb; outer surface labeled with “Fragile” and “Do Not Bend” for paper goods.
Service choice
| Value range | Service options |
|---|---|
| Under $50 | First-class with tracking; no insurance |
| $50–$250 | USPS Priority Mail + tracking; insurance optional |
| $250–$2,500 | USPS Priority Mail + insurance + signature confirmation |
| $2,500–$5,000 | USPS Priority + max insurance, or UPS/FedEx insured |
| $5,000+ | UPS or FedEx insured + adult signature required |
Documentation
Before sealing the package:
- Photograph the item.
- Photograph the packaging materials beside it.
- Photograph the sealed package with the tracking label visible.
If a claim becomes necessary, this is the documentation that turns a denial into an approval.
Common mistakes
- Painter's tape vs packing tape — use painter's on the top loader so the receiver can extract without forcing.
- Under-insured shipments — your declared value should match the realized sale price, not the wholesale price.
- Skipping signature confirmation above $250 — porches are not safe storage.
- Loose packing — items must not shift inside the box during a 5-foot drop test.
