The mark is almost always on the plastic, not the card. A slab is a Pokemon card sealed inside a hard, tamper-evident plastic holder after grading, so light marks sit on the outer case. That matters because the card inside stays protected even when the case looks worn. Learning to check the layers helps you buy, sell, and store with more confidence.

How can you tell where the scratch is?
Hold the slab under a lamp and tilt it slowly side to side. A scratch on the outer case will catch light, shift position, and may stop at the label edge or seam. Look closely at depth and feel.
Case scratches often look white or hazy, sit above the card art, and may catch a fingernail when you pass it lightly across the surface. A mark on the card itself stays fixed under the art, lines up with the printed surface, and does not move when reflections move. Try this quick check:.
- Tilt the slab and watch whether the mark moves with the glare
- View from the side to see if the line sits on top of thick plastic
- Compare front and back, since many case scuffs appear on only one side
- Wipe dust gently with microfiber first, so lint is not mistaken for damage
Why do slabs scratch so easily?
Grading holders use clear, rigid plastic chosen for visibility and security, not scratch resistance. Normal handling, stacking, shipping, and display leave fine hairlines quickly.
Soft sleeves, display stands, and hard shelves can all add marks. Even careful storage causes light scuffs when slabs slide against each other in a box or case.
Does a scratched case change the grade?
No, a scratched holder does not change the condition of the card inside. The grade was assigned before sealing and refers to the card, not the plastic around it.
The case can still affect a sale. Heavy haze makes photos look poor, hides gloss and edges, and makes buyers hesitate. A clean-looking slab is easier to inspect and easier to trust.
Should you clean, reslab, or leave it alone?
Leave light hairlines alone if the card displays well and photos stay clear. Cleaning and polishing carry risk, especially around edges, seams, and embedded labels. For light dust and fingerprints, use a clean microfiber cloth and gentle straight strokes.
Avoid paper towels, rough fabrics, household cleaners, abrasives, and buffing machines, which can add haze or weaken the holder. Consider professional reslabbing when scratches block the card, label, or barcode, or when cracks, chips, or loose seams appear. The grading company replaces the holder without changing the original grade if the seal remains intact. Store slabs upright, sleeved, and separated to slow future wear.
