Slab Bumper
Quick Specifications
A rubber or silicone guard that fits around the edges of a graded card slab to protect against drops and chips. Bumpers don't affect the grade — they protect the case itself, and make stacked storage and handling safer for high-value slabs.
Condition & Grading Challenges
Standard Condition Check: Inspect all four corners under 10x magnification. Ensure surface is free of wax stains and gum residue (vintage) or print lines (modern).
Investment Profile
General Market: Tracks with the broader sports card index (SCI-500).
