Guide 04 / Preparation · 7 minute read · Requirements checked 31 August 2026

Quick answer: To prepare cards for grading, read your grader's current packing rules first, set up a clean workspace, photograph each card, then transfer it into a clean, well-fitting sleeve and the holder your grader specifies, without force. Never clean, polish, press or treat the card: preparation preserves condition, it does not improve it.

Preparing a card for grading should preserve its condition, make it easy to identify and allow the grading team to remove it safely. The most important decisions happen before the card is out of its sleeve: choosing the correct supplies, clearing the workspace and checking the current instructions for the service you purchased.

Read the submission rules before opening supplies

Use the grader's current instructions for your submission route. Do not build a package from a mixture of an old video, a friend's method and a different company's kit.

PSA, CGC and TAG all publish their own packing guidance. The details are not interchangeable, particularly where sleeve features, holder formats and additional packaging are concerned. A product that is convenient for personal storage is not automatically suitable for every grading submission.

Before starting, confirm the card's eligibility, the service order, the required sleeve-and-holder format and how the cards must be organised. A thick, oversized, miniature or unusual-material card needs its own eligibility and fit check.

Set up a controlled workspace

Choose a stable table with good lighting and enough room to separate unprepared cards from completed ones. Remove drinks, food, loose packaging scraps and anything that can shed grit. Keep pets and unnecessary movement away from the work area.

Lay out fresh sleeves, appropriate holders, a clean support surface and your inventory. Wash and dry your hands thoroughly. Hold cards gently by their edges without squeezing or flexing them.

Work in a simple left-to-right sequence: waiting for inspection, being prepared, completed. Keep only one exposed card in the active area. Do not stack bare cards as a temporary shortcut.

Practise the transfer with an inexpensive card of the same format before handling an important example. Practice is for learning the movement, not for proving that a holder is accepted by a grading company.

Confirm identity and take your records first

Photograph the front and back under useful light. Include the exact variant and any serial number in the inventory, and note existing marks. Keep personal order information separate from photographs you may later post publicly.

Use an identifier in the inventory or filename rather than sticking a label to the card. For repeated copies, photograph distinguishing features and maintain their order throughout the preparation process. Once a card is safely prepared, avoid taking it out again simply to make more photographs for social media.

Should you clean cards before grading? No.

Avoid applying water, alcohol, household cleaners, polish, wax, sprays or other chemicals. Do not use erasers, abrasive pads, scraping tools or a cloth to buff the face. Do not colour edges, trim fibres, press out dents or use heat, steam or deliberate humidity changes to alter the card.

This is both a condition risk and a grading issue. PSA's standards identify evidence of cleaning and other alterations as possible reasons for a non-standard or no-numerical-grade result. CGC also distinguishes altered items within its grading framework. It is not safe to assume that an unsuccessful grading attempt will be free.

A visible speck is not an invitation to rub. First determine whether it is on the sleeve rather than the card. Replacing a dirty sleeve is different from treating the card's surface. If contamination appears attached to a valuable or fragile card, stop and seek appropriate advice.

Some services may offer a defined preparation option under their own terms. That does not establish that a home treatment is equivalent or permitted.

How to sleeve a card for grading

Inspect the empty sleeve for grit, wrinkles, damaged seams and an uneven opening. Discard a questionable sleeve: an inexpensive consumable is not worth risking the card you are preparing.

Choose a fit that allows the card to enter without force. Align the card and opening while supporting the card by its edges. Open the sleeve gently with your fingers, keeping hard tools away from the card. Introduce the card squarely and move slowly enough to notice resistance.

If an edge catches, stop. Withdraw slightly while maintaining support and correct the alignment. Do not push harder, bend the card or tap it against the table to make it move.

Keep scissors and blades away from the handling area. A tutorial that involves cutting a sleeve corner is not a universal requirement; use an appropriate undamaged sleeve instead.

Add the outer holder without forcing the fit

Inspect the empty holder before use. Confirm that it suits the card's size, thickness and the grader's requirements. Exterior measurements alone do not establish the dimensions of the usable pocket.

Support the holder while gently opening its mouth as designed. Guide the sleeved card into the pocket without letting a corner drag against a seam. Avoid squeezing across the face or bending the assembly to make a tight combination fit.

The card should sit fully protected and remain easy to remove without tools or force. If the sleeve wrinkles or the card bows, stop and reassess the combination. Do not attach adhesive directly to the card, and follow the selected grader's instructions for the holder opening and any identifying information.

Use the minimum appropriate layers

More layers are not automatically safer. Each layer changes fit and removal, and each transfer is another handling step. A tightly fitted inner sleeve that works well in a playing deck may not be the sensible choice for a grading submission.

For ordinary storage, double sleeving can be a deliberate system using compatible products. For grading, follow the company's specified method rather than treating a full protection stack as compulsory. Our guide Card Sleeves, Toploaders and Semi-Rigid Holders explains the different roles.

Special situations that should make you pause

  • A strongly curved card: do not press, heat or humidify it. Confirm the service can accept it and choose a protective approach that does not force it flat.
  • A thick card or unusual shape: check eligibility and holder thickness before handling it. A familiar width and height do not guarantee sufficient pocket capacity.
  • A signed card: avoid contact with the signature and verify the required autograph service.
  • A card already in another company's slab: investigate crossover, review or reholder options before removing it. Opening a slab creates damage risk and may affect protections attached to the existing holder.

Finish with a preparation check

Confirm that the card is fully protected, visible where required, correctly associated with its inventory entry and placed in submission order. Record completion in your list rather than relying on memory. Once prepared, keep the cards together in a clean, secure container until packing.

Frequently asked questions

Should I wipe the card with a microfibre cloth?

Do not treat wiping as routine preparation. Even a soft cloth can carry particles, and rubbing can affect delicate surfaces. A clean sleeve and careful handling are not the same as cleaning the card itself.

Are tight inner sleeves essential for grading?

No universal rule requires them. Use the current instructions for the selected service and a fit that does not create pressure or difficult removal.

Can I use Saver Pro sleeves and holders for grading?

Compare the published dimensions and design of the specific product with the current submission rules. Base Card Sleeves and the Semi Rigid Card Shield serve different protective roles; their product descriptions are not a substitute for a grader's acceptance requirements. Do not assume that a pull-tab sleeve is permitted simply because it fits the holder.

Preserve the condition you actually have

Good preparation is deliberately uneventful: no force, no treatment, no uncertainty about which card is which. When the cards are ready, move on to our packing and shipping guide and keep the same controlled approach.
