Bends & pressure
The sturdy, hard case prevents bending and pressure marks that sleeves alone quickly allow.
Why cards are better protected in a slab
A slab – the sealed protective case of a graded card – is far more than just looks. In this guide we explain what the slab protects your collectible cards from and why graded cards are therefore more value-stable and safer to store.
What the slab protects from
All-round protection for your card
Abrasion & scratches
The card no longer touches anything directly – surface, corners and edges stay untouched.
Moisture
The sealed case keeps out moisture and dirt that can permanently damage cards.
UV light
Protection against fading from sun and artificial light over the years.
More than protection
Value stability, authenticity & trust
A slab preserves the condition at the time of grading – the recorded grade stays traceable and is protected from later damage that would reduce value. In addition, every PGS slab carries a serial number with QR code and a tamper-proof label through which the grade can be verified at any time.
For buyers this means security, for sellers a clear advantage: a sealed, verifiable card builds trust and sells more transparently. How a card arrives at its grade is explained on subgrades and the grading scale.
Slab vs. sleeve
When does a toploader suffice – and when the slab?
Sleeve and toploader are good basic protection for everyday use and shipping – they prevent scratches and light bends. For valuable cards in longer storage, however, they reach their limits: sleeves can slip, release plasticisers or let moisture through, and toploaders offer no fully sealed, dimensionally stable protection. The slab, by contrast, encloses the card firmly and permanently – ideal as soon as value and protection needs increase.
For storage too: keep cards dark, dry and at a stable room temperature, avoid direct sun and store slabs upright or stacked flat. That preserves the conserved condition and keeps the documented grade reliable for years. How a card arrives at its grade is explained by subgrades and the grading scale; the complete workflow is shown on the grading process page.
