What you’ll see

Slabs show their grader and grade on a label, like the real thing, in My collection and in your binders. The cert number links to the grader’s own lookup where the grader has one.

Slabs stay separate from raw copies of the same card. You can record what you paid for each one and see that cost in your portfolio. House of Holos does not provide market prices or slab valuations.
