Selling a lot vs. selling singles
Should you sell your slabs one at a time or as a lot? The real tradeoffs in time, fees and price, and how Cardwel handles lots.
This article explains how Cardwel values a graded sports card before making an offer, so you know exactly where our number comes from.

Every offer we make starts from one question: what has this exact card actually sold for lately? Not what it is listed for. Not what it sold for at the peak. What a buyer paid, recently, for the same card in the same grade from the same grading company.
We pull recent completed sales for the card across the major marketplaces and auction houses, plus established price guides. A 2018 Prizm Luka Doncic rookie in PSA 10 and the same card in BGS 9.5 are different cards to the market, so we only compare like with like.
Why not asking prices? Anyone can list a card for any number. Sold prices are the only proof of what the market will pay.
One grade point can double or halve a card's value, especially at the top end. The grading company matters too, because buyers pay different premiums for PSA, BGS and CGC on different cards. We price from the slab you have, not the slab you wish you had.
Some cards sell the same day they are listed. Others sit for months. A card that moves quickly is worth closer to its comps to a buyer like us, because we are not carrying it for long. Slow movers and cards with very few recent sales get a more careful look.
Two cards with the same grade are not always equal. Centering, color and print quality still show through the case. We also check that the slab is intact and that the cert number matches the card inside.
