SLABABILITY

Before you slab it, know the odds. Scan a card and we'll identify it, read visible condition, check market comps and population data, then price every grade outcome.

03Comps & grade odds

A scan estimates odds automatically from visible condition (and population data, when available) — tune from there, or start from a preset if you're entering a card by hand.

How this calculates, and what it can't know

The grading edge is the expected net proceeds across every grade outcome, weighted by the odds you set, minus what the card nets you sold raw today, minus the all-in cost of grading. If that number is negative, grading destroys value no matter how good the PSA 10 comp looks.

Fee defaults were checked in August 2026 and are editable for a reason: PSA repriced in February and again in May 2026, then paused new Value-tier submissions on June 2 against a roughly 10-million-card backlog. Verify current pricing at PSA, SGC, Beckett or CGC before you ship, and confirm your own marketplace fee rate.

The condition presets are starting heuristics, not pop-report data. Nobody can tell you your real odds from a photo — centering, print lines and edge whitening are graded by a human with a loupe. Tune the odds yourself, and assume you're more optimistic about your own card than the grader will be.

Market values are estimated from multiple provider sources. Asking prices are never presented as completed sales; sold comps are shown separately when available. Review each source's terms before relying on any value.
