What does it mean when a comic is slabbed?
What the slab includes
The slab is a hard plastic case that encloses the comic, with a label that shows the title, issue, grade, and a unique certification number. The comic is sealed so it cannot be removed without breaking the holder, which discourages handling damage.
Slabs are used by grading companies that inspect comics and assign grades. Buyers often pay more for slabbed comics because the grade and authenticity have been checked by a third party.
- Hard plastic holder protects the comic
- Label shows grade and certification number
- Makes condition easier to compare
Handling slabs well
Keep slabs out of direct sunlight, and avoid stacking them under heavy weight. Handle them by the edges, and clean the outside holder gently with a soft cloth if needed.
Check the slab's seal and label for signs of tampering, and verify the certification number with the grading company before you buy or sell.
Slab labels can also be damaged or scratched over time, which may make the information hard to read. Store slabs upright in a rigid case so the label stays clear, and keep receipts for any slabs you buy. Grading services also update their practices over time, so check the company's current guidance if you have questions about an older slab.
Common mistakes
- Assuming a slab guarantees a high grade for every comic inside.
- Opening a slab, which can reduce its value.
