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.
