SlabIndex publishes market analysis, not investment advice. Nothing here is a recommendation to buy or sell, no outcome is guaranteed, and past results — including every figure in the track record — do not predict future ones. Collectibles are illiquid and can lose value. Trade with money you can afford to lose.

Graded market

The half of the market nobody indexes

Most trackers stop at the raw card. The money is in slabs, and slab prices move on population reports. This board scores the gap, after grading costs.

Ranked grading opportunities

A 0–100 score for one trade: buy raw, pay the fee, sell the slab. Hover a score to see it broken down.

45%Submission ROI

Expected slab value against the raw copy plus fee plus shipping.

30%Gem scarcity

How thin the population is at the top grade.

25%Slab momentum

Whether graded prices are already moving.

On grading estimates: these odds come from card age and population shape, not from an inspection of your copy. Centring and surface vary card to card, and a submission can come back well below the modelled grade. A screening tool, never a guarantee.

20,529 cards carry a graded market. 17,336 more are tracked for raw price only.

Population is the supply curve

A print run says how many exist; a population report says how many exist in the condition people pay for. A thin gem population is room the raw price doesn't have.

Fees decide the trade

The fee is fixed per card, so 2× on a $900 card beats 6× on a $20 one. Every score is net of the tier fee and shipping.

Vintage grades badly, and that's the point

Modern cards leave the pack gem mint, so the premium is thin. A 1999 card had to survive 25 years — few did, so the multiple is huge and so is the risk.
