The Pre-Grading Checklist: What to Do Before Your Cards Go in the Mail

Most grading rejections and disappointing grades aren't random. They trace back to something that happened before the card ever reached the grading company — how it was handled, how it was sleeved, how it was packed, and what condition it was actually in when it left your hands.

The submission process itself is straightforward. The prep work is where most collectors leave points on the table.

Here's what to do before your cards go in the mail.

Step 1: Assess the Card Honestly

Before anything else, look at the card under good lighting — ideally a bright LED or natural light at an angle. You're checking for:

• Centering — front and back. Grading services measure this and factor it into the final grade. If a card is visibly off-center to the naked eye, know that going in.
• Corner condition — any fraying, soft corners, or wear. Corners are one of the highest-weighted factors in grading.
• Edge condition — nicks, chips, or roughness along any edge.
• Surface condition — scratches, print lines, staining, or cloudiness on foil and chrome cards especially.
• Back of the card — backs are graded too. Check for creases, stains, and print defects that are easy to miss.

This step isn't about talking yourself out of submitting — it's about going in with accurate expectations. A card you think is a PSA 10 candidate that comes back an 8 is a frustrating and expensive surprise. A card you assessed as an 8 that comes back an 8 is confirmation.

Step 2: Clean the Card — Carefully

Fingerprints, dust, and light surface debris can affect a grade even when the card underneath is clean. Light cleaning before submission is standard practice for serious submitters.

What works:

• A clean microfiber cloth for light surface debris — wipe gently in one direction, not in circles
• Compressed air for dust, especially on textured or foil surfaces where wiping can cause micro-scratches

What to avoid:

• Any cleaning solutions, including water — moisture is a risk on paper stock and can leave residue on foil
• Paper towels or any rough material — these leave micro-scratches that show up under grader lighting
• Touching the card face with bare hands after cleaning — oils transfer immediately

Handle cards by the edges only, always. If you need to set a card down, place it face-up on a clean soft surface — never face-down on anything textured.

Step 3: Sleeve the Card, Then Into a Semi-Rigid

Every card going to grading goes into a soft sleeve first, then into a semi-rigid holder. That's the correct order and the submission standard for PSA, BGS, and CGC.

Semi-rigids — not top loaders — are what grading companies require. The reason is practical: semi-rigids flex slightly, which allows graders to remove cards cleanly without damage.Top loaders are rigid and don’t flex, meaning card extraction requires more direct handling and creates unnecessary risk of damage. PSA explicitly does not accept hard top loaders for submission and may reject or delay orders packed that way.

Insert the card into the soft sleeve carefully — slide it in straight, don't force it, and make sure it's fully seated. The most common sleeve-related damage happens on insertion when the card edge catches the sleeve opening. Once sleeved, slide the card into the semi-rigid and make sure it sits flat and doesn't shift significantly inside the holder.

Top loaders are for storage and display. Semi-rigids are for grading submissions. Keep both on hand and use each for what it's designed for.

Step 4: Pack the Submission Correctly

How cards are packed for shipping matters as much as how they're sleeved. Grading companies receive large volumes of submissions and handle them at scale. Cards that aren't packed properly arrive damaged regardless of how well they were prepped.

The standard approach:

• Stack semi-rigids together with cards all facing the same direction
• Place cardboard separators every 10–15 cards, then sandwich the full stack between two pieces of cardboard — bind the cardboard with rubber bands or painter’s tape, not the holders directly
• Place stacks in team bags to protect against moisture
• Wrap the bagged stack in bubble wrap — enough that nothing moves inside the outer box
• Use a rigid box, not a padded envelope — padded envelopes compress under pressure and provide almost no protection against impact
• Fill any empty space with additional padding so nothing shifts in transit

Follow the specific submission instructions from whichever grading service you're using — PSA, BGS, and CGC each have their own requirements around how cards should be organized and documented inside the package.

PSA, for example, accepts FedEx and USPS but not DHL — always check current grading service carrier requirements before shipping.

Step 5: Document Everything Before It Leaves

Photograph every card before it goes in the mail. Front and back, under good lighting. This is a record of condition at the time of submission. If a card comes back with damage that wasn't there when you sent it, documentation is what makes a case possible.

Keep a copy of your submission form, declared values, and tracking information. Grading turnaround times vary significantly across services and tiers, and having a full paper trail makes any follow-up significantly easier.

Bottom Line

Grading is expensive and the turnaround is slow. The prep work is the one part of the process you fully control. Cards that arrive clean, correctly sleeved in a semi-rigid, properly packed, and honestly assessed come back with the grades they deserve.

None of this is complicated. It's just doing it right before the card leaves your hands.
