The Short Answer
- The Sandwich Method protects cards with three layers: penny sleeve, semi-rigid holder, and team bag.
- Never use tape directly on card holders — residue damages cards when graders remove them.
- Ship with insurance equal to declared value plus grading fees.
- Use bubble wrap between card bundles, not just around the outside of the box.
Packing Supplies You Need
- Penny sleeves: Ultra-clear polypropylene. $3–$5 per 100.
- Semi-rigid card holders: Card Saver I (for standard cards) or Card Saver II (for thicker cards). $8–$12 per 25.
- Team bags: Resealable polypropylene bags that hold the semi-rigid holder. $5–$8 per 100.
- Bubble wrap: Small-bubble (3/16-inch) for wrapping bundles. $10–$15 per roll.
- Cardboard box: USPS Small Flat Rate Box (8-5/8" × 5-3/8" × 1-5/8") or similar rigid box.
- Packing tape: Clear shipping tape for sealing the box.
- Packing peanuts or crumpled paper: To fill empty space and prevent shifting.
The Sandwich Method
The Sandwich Method is the industry standard for shipping cards to grading companies:
- Step 1 — Penny Sleeve: Slide the card into a clean penny sleeve. This prevents surface scratches and fingerprints.
- Step 2 — Semi-Rigid Holder: Place the sleeved card into a Card Saver I semi-rigid holder. Do not force thick cards — use Card Saver II for jersey or patch cards.
- Step 3 — Team Bag: Slide the Card Saver into a resealable team bag. This keeps the holder clean and prevents it from sliding out.
- Step 4 — Bundle Wrap: Group 5–10 card sandwiches together. Wrap the bundle in bubble wrap with the bubble side facing inward.
- Step 5 — Box Placement: Place bundles in the box with packing material between them. Never let card bundles touch each other directly.
- Step 6 — Fill Void Space: Use packing peanuts or crumpled paper to fill all empty space. The box should not rattle when shaken.
Box Selection
Choose a box that is:
- Rigid: Double-walled cardboard is preferred for submissions over 20 cards.
- Right-sized: The box should be full enough that contents cannot shift. Too large and cards slide around; too small and they are compressed.
- Taped on all seams: Reinforce all box edges and seams with packing tape.
Recommended: USPS Small Flat Rate Box for 1–20 cards, Medium Flat Rate Box for 21–50 cards.
Shipping and Insurance
- Declared value: List the full market value of all cards combined. PSA, BGS, and CGC use this for insurance during their possession.
- Outgoing insurance: Insure your package for the declared value plus grading fees. Use USPS Priority Mail Insured, UPS, or FedEx with declared value coverage.
- Return shipping: Prepay return shipping if the grader offers it, or include a prepaid return label.
- Tracking: Always use a trackable service with signature confirmation for high-value submissions.
Common Packing Mistakes
- Tape on card holders: Never tape Card Savers directly. Tape residue transfers to cards when graders remove them.
- Top loaders without tape: If using top loaders, tape the top closed. But semi-rigid holders (Card Savers) are preferred.
- No bubble wrap between bundles: Cards in Card Savers still shift and collide. Bubble wrap between bundles is essential.
- Under-insured packages: A $5,000 submission shipped with $100 insurance is a disaster if the package is lost.
- Weak boxes: Thin envelopes or padded mailers are not sufficient for grading submissions. Use a rigid box.
Frequently Asked Questions
How do you pack cards for grading submission?
Use the Sandwich Method: penny sleeve the card, place it in a semi-rigid Card Saver holder, seal in a team bag, wrap bundles in bubble wrap, and ship in a rigid box with void fill.
Should I use top loaders or Card Savers for grading?
Card Savers (semi-rigid holders) are preferred by PSA, BGS, CGC, and SGC. Top loaders are acceptable but require tape across the opening.
How much insurance do I need for grading submissions?
Insure for the full declared value of all cards plus grading fees. A $3,000 submission with $500 in grading fees should be insured for at least $3,500.
Can I ship cards in a padded envelope?
No. Padded envelopes do not provide enough protection for grading submissions. Always use a rigid cardboard box.
How many cards can I ship in one box?
USPS Small Flat Rate Box handles 1–20 cards comfortably. Medium Flat Rate Box handles 21–50 cards. For 50+ cards, use a custom sturdy box with ample padding.
