What’s a Coin Slab?
TL;DR — A slab is a hard, transparent capsule sealed by an independent grading service. It keeps your coin safe, proves it’s genuine, and freezes its condition at a known score.
Why Slabs Exist
- Counterfeits are common. A slab’s barcode and hologram link to an online cert page, scaring off fakes.
- Cleaning ruins value. A slab is tamper‑proof, so buyers know the coin hasn’t been altered since grading.
- No more arguments. Everyone sees the same grade on the label, so deals close faster.
Analogy: A slab is to coins what a PSA case is to Pokémon cards or a CGC case is to comics.
