How to prepare Pokemon cards for grading: self-assessment, cleaning, packaging, and what PSA, BGS, and CGC actually look at

What graders actually evaluate

All three major grading services — PSA, BGS (Beckett), and CGC — evaluate cards using four primary criteria: centering, corners, edges, and surface. Each criterion is assessed separately, and the overall grade reflects the weakest area, not an average. A card with perfect centering but damaged edges will receive a grade based on the edge damage.

Centering is measured as the ratio of border width from the artwork to the card edge on opposite sides. A card with significantly more border on the left than the right is off-center. PSA accepts up to 60/40 front and 90/10 back for a PSA 10 on some sets. BGS is stricter, with subgrades assigned separately. Corners are assessed for whitening, rounding, and fraying. Edges are checked for chipping, nicks, and roughness. Surfaces are inspected for scratches, print lines, staining, and holo damage.

Understanding this framework changes how you evaluate candidates. The Pokemon card condition guide gives you the vocabulary to assess each factor accurately before spending on submission.

Self-assess honestly before selecting candidates

Grading is only profitable when the certified grade adds enough value to cover the submission cost and the difference between the graded and raw market price. Submitting cards that are likely to grade PSA 7 or below rarely makes financial sense because the certified premium for those grades is small and the submission cost is fixed.

Self-assessment requires good lighting and a jeweler's loupe or macro camera lens. Examine corners under raking light at multiple angles — corner whitening is easiest to see when light hits the edge at a low angle. Check holo surfaces by tilting the card slowly under a single bright source and looking for fine scratches. Edges should be even under direct light without chips or fraying.

If you are not confident about a card's value before grading, use the price checker to compare raw versus graded market prices and confirm the submission makes economic sense.

Clean the card safely before submission

Light surface cleaning before submission removes fingerprints and dust that could appear as surface issues under grader lighting. The only safe method is a clean, dry microfiber cloth with minimal pressure. Never use alcohol, chemical cleaners, or abrasive materials — any chemical residue or scratch introduced during cleaning will be visible to graders and can turn a borderline 9 into an 8.

Do not attempt to clean corners or edges. Any contact with corners risks rounding or adding micro-whitening. Surface cleaning is appropriate only for the face and back of the card, avoiding corners and edges entirely. For more detail on safe cleaning technique, see the Pokemon card cleaning guide.

Sleeve and package cards correctly for shipping

A card that arrives at the grading company in worse condition than it left your hands has failed before it was evaluated. The packaging step is where many collectors make avoidable mistakes.

Each card should be placed in a clean penny sleeve first, then inside a firm top loader. Tape the top of the top loader shut — do not let the card float inside. Cards that shift during transit can develop edge or corner wear from contact with the inside of the holder. Place the loaded top loaders inside a bubble-wrapped parcel within the shipping box. Cards should not be able to move.

Follow the specific submission requirements from each grading service exactly. PSA, BGS, and CGC all have different form requirements, service level options, and packaging specifications. Submission errors can add weeks of processing delay or result in cards being returned ungraded.

Which cards are worth submitting

The general rule is that a card is worth grading if the PSA 9 or PSA 10 price is significantly higher than the raw price, and the card has a realistic chance of hitting that grade based on your honest self-assessment. For most modern bulk rares this math does not work. For vintage cards, key Pokemon, and high-demand modern chase cards, the premium for certified grades is real and the submission makes sense.

If you are unsure whether you should grade at all, the Pokemon card grading guide walks through the decision criteria in detail. Grading is not the right move for every valuable card — it depends on how you intend to hold, sell, or display it.

Track submission status and log returned grades

All three major grading services provide order tracking. After submission, log each card's submission date, declared value, and service level so you can compare return time against estimates and track which service performs best for your card type. When grades return, log the result alongside the original raw condition assessment — over time this helps you calibrate your pre-submission evaluations.

The PokeSnap collection app lets you track raw and graded cards in the same system, so you can see your full collection value whether the cards are certified or not.
