Guide 12 / After grading · 7 minute read · Requirements checked 31 August 2026

Quick answer: When graded cards come back, reconcile every slab against your inventory, check label, certificate and holder, and report genuine discrepancies within the company's deadline (PSA: five calendar days of receipt, when checked). Then store slabs in a slab sleeve or fitted compartment, in a stable, dry indoor room away from direct sunlight and heat. A slab is not waterproof or climate control.

The grading process is not finished when the parcel reaches your door. A slab changes how you handle a card, but it does not remove the need to manage light, heat, moisture and physical pressure.

Open the return deliberately

Choose a clean table with enough room to lay out the cards and paperwork. Keep the outer shipping label, packaging and order information until you have completed the inspection.

Photograph visible parcel damage before opening. Open carefully, keeping blades and scissors away from the contents. For a high-value shipment, documenting the opening can provide an additional record, though a video is not a guarantee that a claim will be accepted. Count the items before putting anything away.

Check the card, label and certificate together

For each slab, verify the card's set, number, language, variation, signature-related details and grade designation. Match the certificate number to your records and, where available, to the company's verification page and images.

Do not treat a database match as proof on its own. PSA explicitly warns that a valid certification number does not eliminate counterfeit risk. For purchased slabs, evaluate the item, holder, seller history and available records together rather than relying on a cropped certificate screenshot.

Copy the issued designation accurately. Do not convert a Mint+, Gem Mint, Pristine or autograph grade into another term because it sounds more attractive.

Separate three kinds of problems

  • A label or identity discrepancy: the description, language, number, variant or other recorded detail appears wrong. Document the exact mismatch and ask the grading company to investigate.
  • A physical-condition concern: involves the holder, the card or the shipping package. Preserve the evidence and compare the return with your pre-submission record without opening the slab.
  • Disappointment with the grade: review the applicable standards and any available notes, subgrades or reports before deciding whether a formal review is justified.

Act promptly on genuine discrepancies

Reporting windows differ between companies and services. As a dated example, PSA's terms checked for this guide require written notification of received-item damage, discrepancies or errors within five calendar days of receipt. That is a PSA-specific requirement, not a universal deadline.

Keep the slab intact while support considers the issue. Do not pry it open, attach a homemade correction label or attempt to polish away evidence of damage. Review, crossover and reholder services address different objectives; none should be described as a purchased grade increase.

Build a useful graded-card inventory

Record the card identity, grading company, grade designation, certificate number, submission reference, acquisition cost, grading-related cost, date received and storage location. Save front and back slab photographs and any report or grader notes.

For value records, note the valuation date and basis rather than storing one timeless number. Keep a backup separate from the physical collection, and limit public access to documents containing personal addresses or shipping details.

How to protect the outside of the slab

Use a sleeve designed for the actual holder dimensions when an outer cover suits your storage routine. It provides a replaceable surface for ordinary handling, but it does not change the card's grade or repair a scratched holder.

Saver Pro's PSA Graded Slab Sleeves are made for PSA holders. Check the fit instead of assuming they accommodate every BGS, CGC, TAG or oversized slab equally well. Slide the holder in without forcing it, and replace a dirty or damaged sleeve rather than adding layers.

Avoid abrasives, solvents or polishing compounds as routine slab care. For a significant holder issue, ask the grading company about the appropriate service.

How to store graded cards: choose the room first

Store the collection in a stable indoor environment, away from leaks, direct sunlight, heaters and places that become very hot. Avoid attics, vehicles and other locations where conditions change sharply.

General conservation guidance for paper and photographs emphasises managing temperature, humidity and light exposure. Trading cards use varied papers, inks and finishes, so do not treat one rigid number as a universal specification. A small temperature-and-humidity monitor helps you understand the actual storage location over time.

A protective case is not climate control. PSA's guarantee specifically excludes certain deterioration associated with harsh environmental conditions and events such as flooding or fire.

Displaying graded cards: reduce light exposure

Keep valuable cards out of direct sunlight and avoid permanent exposure to strong display lighting. A UV-related product claim is not permission to place a slab on a sunny windowsill: UV filtering does not eliminate every form of light damage, and it does not remove heat exposure.

For a long-term display, consider whether a reproduction can occupy the brightest location while the original remains safely stored. If displaying originals, use a secure stand or compartment that supports the slab without clamping the card area. For raw cards on display, a correctly specified Magnetic Card Case can be one option.

Make storage physically calm

Choose compartments that fit the holders without crushing them. Use dividers or supports so slabs do not slide, collide or carry unnecessary weight. Do not overfill a case until closing it compresses the contents.

For dampness, condensation or suspected mould, isolate the problem and seek professional guidance. Do not heat the slab, freeze it or introduce liquid. If you use moisture-control products, follow their instructions and do not place loose desiccant directly against collectibles.

Recheck after moves and periodically in storage

A simple inspection routine can look for sleeve damage, holder damage, unexpected moisture, dust and changes in the storage environment. Reconcile the inventory after moves, events or sales. For shipping a graded card later, use an appropriately supported package.

Frequently asked questions

Are graded card slabs waterproof?

Do not rely on a slab as waterproof protection unless the specific manufacturer provides a relevant claim and conditions. Keep cards away from liquids regardless.

Does a scratched slab mean the card's grade has changed?

A scratch on the holder and damage to the enclosed card are different issues. Inspect carefully without opening the slab and ask the grading company about the appropriate service when necessary.

Will reholdering improve the grade?

No. Treat reholdering as a holder-related service, not a way to buy a higher numerical result.

Where should I store graded cards?

In a stable, dry indoor room away from direct sunlight, heaters, attics and vehicles, in fitted compartments that support the slabs without pressure.

Protect the record as well as the card

A well-kept slab, accurate inventory and sensible storage environment work together. The goal is not just an attractive display today, but a collection whose identity, condition history and location remain clear over time. Save the Grade.
