How to Prepare Your Cards for Grading: The Complete Checklist

Every card submitted for grading represents a financial commitment — your money, your time, and the inherent risk of shipping irreplaceable assets. Proper preparation isn't optional; it's the single most controllable variable in whether your card comes back a Gem Mint 10 or a disappointing 8.

Step 1: Evaluate Before You Submit

Not every card deserves the submission fee. Before you pack anything, perform a honest self-assessment:

Centering check: Hold the card at arm's length under even lighting. For PSA, a 60/40 ratio on the front and 65/35 on the back is the general threshold for a Gem Mint 10. If you can visibly see one border wider than the opposite, you're likely looking at a 9 at best.

Surface inspection: Tilt the card under a bright light at various angles. You're looking for print lines, scratches, surface dents, or any debris embedded in the coating. On chrome and refractor cards, even a single fingerprint can drop a grade.

Corner and edge evaluation: Use a loupe (5x–10x magnification) to inspect all four corners. Whitening, nicks, or soft corners are grade killers. Run your thumbnail gently along each edge feeling for any roughness or paper separation.

Step 2: Clean with Precision

If your card passes the visual inspection, a gentle cleaning can remove surface dust and oils without causing damage.

✅ Do: Use a clean, lint-free microfiber cloth. Gently buff the surface in one direction — front and back.

❌ Don't: Never use paper towels, tissues, or any chemical cleaners. These introduce microscopic scratches that are invisible to the naked eye but devastate grades under magnification.

❌ Don't: Never touch the surface of the card with bare fingers after cleaning. Handle by the edges only, or use cotton gloves.

Step 3: Sleeve and Contain Properly

This is where many collectors make critical mistakes that delay processing or risk damage:

⚠️ Critical warning: Do NOT submit cards in top-loaders, hard acrylic cases, or screw-down holders. Submissions in these containers will experience processing delays and increase the risk of damage during extraction at the facility.

Step 4: Organize and Label

For bulk submissions, organize your cards in the exact order they appear on your submission form. Mismatched orders create delays and increase the chance of data-entry errors at the facility.
