Learn from others’ errors to safeguard your cards.

  • Overhandling
    Mistake: Touching card surfaces or sliding cards across rough tables.
    Fix: Handle by edges only on a soft mat. (OwnerChip protection tips)
  • Using Poor Materials
    Mistake: Old, cloudy, or PVC sleeves; no sleeves at all.
    Fix: Always use fresh, acid-free, PVC-free sleeves and semi-rigid holders. (Card Shellz grading supplies guide)

    Mistake: Loose cards in box, no cushioning.
    Fix: Follow “sleeve → semi-rigid → cardboard sandwich → bubble wrap → snug box” workflow. (Video guide)
  • Excessive Tape
    Mistake: Using duct tape or wrapping cards directly, leaving residue.
    Fix: Use small amounts of painter’s tape only on holders or cardboard. (Black Label grading tips)

    Mistake: Storing cards in hot cars or damp rooms.
    Fix: Maintain stable, cool, dry conditions; use dehumidifier or silica packs if needed. (Sportzoo protection blog)

FAQ

  • How do I choose the right protective materials?
    Always select acid-free, PVC-free sleeves and semi-rigid holders (Card Saver 1) to minimize the risk of sleeve-induced scratches and corner damage.
  • Can I use toploaders instead of semi-rigid holders?
    Toploaders offer rigid protection, but some grading companies prefer Card Saver holders for easy card withdrawal without scratching.
  • What if my cards arrive damaged?
    Transit damage becomes part of the official grade; always overpack with bubble wrap, cardboard sandwiching, and double-boxing to prevent this.
  • Is it necessary to remove cards from magnetic holders?
    Yes—magnetic cases can leave marks or make centering checks difficult, so transfer cards to approved holders before submission.
  • How should I store long-term before submission?
    Keep cards upright in acid-free boxes at 60–70°F and 40–50% humidity; include silica gel packets to manage moisture.
