Card valuation

Know what every slab is actually worth

Real comparable-sale valuations on every graded card — matched to the exact cert and grade, aggregated from where cards really trade, and refreshed as the market moves.

Beyond a price guide

A static price guide tells you what a card was worth months ago. Slabline values each slab from recent real sales of the same graded card, so your total reflects the live market — the number that matters for selling, insuring, or just knowing where you stand.

Every major grader

PSA, BGS, SGC, CGC, and TAG — across baseball, basketball, football, soccer, Formula 1, hockey, Pokémon, and Magic. Add a card by cert and the value, image, and price history populate automatically.

How the valuation works

Matched to the exact card

Valued by certification number and grade — not a rough series average. A PSA 10 and a PSA 9 of the same card are priced separately, as they trade.

Real comparable sales

Aggregated from recent sold listings across eBay, Heritage, Goldin, and PWCC. More comps mean a tighter, higher-confidence value.

Always current

Values refresh with the market, so your collection total and insurance schedule reflect today — not what you paid.

Confidence you can see

Each value shows how many comps backed it and a low–high range, so you know how solid the number is.
