A coin slab is a type of holder for a coin. Slabbed coins are typically from coin grading companies. The practice of sending coins to third-party grading companies and then "slabbing" them began in 1986.

When a grading company grades a coin, it is sealed in a tamper-proof slab with a barcode and a hologram. To prevent counterfeiting, holograms were attached to the graded coin slabs beginning in 1989. Earlier coin slabs did not have a hologram.
