How to Prepare Cards for Grading: Supplies, Sleeves, and Packaging

Why Preparation Matters

The way you prepare and ship your cards to a grading company directly impacts the condition in which they arrive. A card that leaves your hands as a potential PSA 10 can arrive as a PSA 9 if it suffers damage in transit due to poor packaging. Worse, improper preparation can cause a grading company to return your cards ungraded - and you still pay for shipping both ways.

Good preparation is not complicated, but it requires the right supplies and attention to detail. This guide covers everything from the first sleeve to the sealed shipping box.

Required Supplies

Before you prepare a single card, gather these materials:

Penny Sleeves ($2-4 per 100)

Standard soft clear sleeves - the first layer of protection. Use new sleeves only; dusty sleeves can scratch cards. Standard size fits 2.5" x 3.5" cards (Pokemon, Magic, sports). Japanese-size and oversized cards need appropriately sized sleeves.

Card Saver 1 Semi-Rigids ($8-15 per 50)

The industry-standard holder for grading submissions. PSA specifically recommends Card Savers over top loaders. The thinner, flexible material lets grading staff extract cards safely. Do not substitute top loaders, screw-down cases, magnetic holders, or snap cases.

Painter's Tape ($3-5)

Low-adhesive tape for securing Card Savers during shipping. Never use scotch tape, packing tape, or duct tape - they leave residue and risk damaging cards.

Packing Materials

Small cardboard box (inner), larger shipping box (outer), bubble wrap or packing paper for cushioning, and rubber bands for bundling Card Savers (never directly on cards).

Step-by-Step Preparation

Step 1: Clean Your Workspace

Work on a clean, flat, dust-free surface. A microfiber cloth on a table works well. Remove any food, drinks, or materials that could contaminate your cards. Wash and dry your hands thoroughly, or wear clean cotton gloves.

Step 2: Sleeve Each Card

Pick up the card by its edges - avoid touching the front or back surfaces.

Insert the card into a penny sleeve top-first (the top edge of the card goes into the sleeve opening first). This means when you later insert the sleeved card into a Card Saver, the sleeve opening faces down and the card cannot slide out.

Push the card all the way to the bottom of the penny sleeve so it sits snugly against the sealed end. The card should not be loose or floating inside the sleeve.

Common mistake: Inserting the card bottom-first, which leaves the sleeve opening at the top. When the Card Saver is handled vertically, the card can slide out of the sleeve inside the Card Saver, resulting in surface contact and potential damage.

Step 3: Insert Into Card Saver

Take the penny-sleeved card and insert it into a Card Saver 1. The card should slide in smoothly. Do not force it - if there is resistance, the card may be catching on the Card Saver edge.

The card should be visible through the Card Saver's clear front. Verify the card is face-up (front of card visible through the Card Saver's front window) and positioned properly.

Do not tape the Card Saver shut. Some people tape the top opening - do not do this. Grading companies need to extract the card from the Card Saver during processing, and tape complicates extraction and risks adhesive contamination. The Card Saver's natural friction is sufficient to keep the card in place.

Step 4: Label Your Cards (Optional but Recommended)

Write a small number on a sticky note or piece of painter's tape on the back of each Card Saver corresponding to the card's line number on your submission form. This helps the grading company match cards to your order and helps you verify the submission when it returns.

Use a fine-tip marker on the tape, not directly on the Card Saver. Marker on the Card Saver itself can potentially transfer to the card in extreme heat conditions.

Step 5: Bundle and Stack

If submitting multiple cards, stack your Card Savers neatly and wrap a rubber band around the bundle. The rubber band goes around the outside of the Card Saver stack - never in direct contact with any card surface.

For larger submissions, create bundles of 10-15 cards each. This keeps bundles manageable and prevents excessive pressure on cards at the bottom of a tall stack.

Step 6: Pack the Inner Box

Place your Card Saver bundle(s) into a small cardboard box. The cards should fit snugly - they should not rattle or shift when you shake the box gently. Fill any dead space with crumpled packing paper or small pieces of bubble wrap.

Include your printed submission form in the box, on top of or next to the cards.

Close and tape the inner box securely.

Step 7: Double-Box

Place the sealed inner box inside a larger shipping box. Surround the inner box with bubble wrap, crumpled paper, or packing peanuts so that the inner box is cushioned on all sides. The inner box should not shift when you shake the outer box.

The double-box method is your primary defense against shipping damage. The outer box absorbs impacts, the cushioning material dampens shocks, and the inner box provides the final layer of rigid protection.

Seal the outer box with packing tape. Write your PSA submission number (or equivalent reference number) on the outside of the box.

Critical Mistakes to Avoid

Tape on Cards

Never apply tape of any kind directly to a trading card. This seems obvious, but grading companies report receiving cards with tape on them regularly - sometimes tape holding a "note" to the card, sometimes tape used to "repair" a corner. Any tape contact can leave residue, lift surface material when removed, or cause permanent adhesive damage.

Rubber Bands on Cards

Rubber bands should only go around bundles of Card Savers, never directly around raw cards or penny-sleeved cards. Direct rubber band contact creates pressure lines across the card surface and can cause permanent indentation over time.

Overstuffing Penny Sleeves

Some collectors put two cards back-to-back in one penny sleeve to "save sleeves." This creates surface-to-surface contact between the two cards, and any movement causes friction scratches on both. One card per penny sleeve, always.

Using Dirty or Reused Sleeves

Dust inside a sleeve becomes an abrasive particle that scratches your card. Use fresh sleeves from a new pack for grading submissions.

Using the Wrong Holders

Top loaders, snap cases, magnetic cases, and screw-down holders are all wrong for grading submissions. Card Saver 1 is the standard. Use it.

Shipping Without Insurance

Insure the shipment for the full declared value. A lost package without insurance means you lose both the cards and the grading fees.

Special Cases

Thick cards (GX full arts, memorabilia cards) may not fit in standard Card Saver 1 holders. Card Saver 2 and Card Saver 4 accommodate thicker cards.

Vintage cards may be slightly different in size and are more fragile. Handle with extra care during sleeving.

Japanese cards are smaller than English-language cards and require Japanese-size penny sleeves (labeled "mini" or "small").

Supply Checklist

• Fresh penny sleeves (correct size)
• Card Saver 1 holders
• Painter's tape and fine-tip marker
• Rubber bands, small inner box, larger outer box
• Bubble wrap or packing paper
• Packing tape and printed submission form

The investment in proper preparation - maybe $10-20 in supplies - protects cards worth hundreds or thousands of dollars. Before you get to preparation, make sure you have screened your cards. Run them through ZeroPop's scanner or a manual pre-grading checklist to confirm they are worth the submission.
