Find slabs
the market
got wrong.
Discover graded Pokémon cards that may be listed below recent sold-market prices. We check the details, compare real sales, and show which listings deserve a closer look.
Not every listing can be scored. No profit promises, authentication or whole-market claims.
How a sweep works
Search the market
We look through active eBay listings for graded cards matching your interests.
Identify the slab
We check the card, set, number, variant and grading details.
Check real sales
We compare qualified completed sales, excluding evidence that doesn’t match.
Spot the opportunity
We compare the ask with the sold-market median and calculate a Deal Score when evidence is sufficient.
Deal Score and Confidence: what’s the difference?
Deal Score · 0–100
How attractive the asking price is compared with the median of qualified recent sales.
Confidence · LOW / MEDIUM / HIGH
How strong the evidence supporting that comparison is.
A high Deal Score means the ask looks attractive. High Confidence means stronger evidence. Neither guarantees profit or authenticates the slab.
Every number has a source
Market information is classified before it is used. Asking prices, completed sales, third-party references and identity confirmations are never mixed together.
Insufficient evidence
When too few qualified sales exist, SlabSweep says so instead of inventing precision.
Active ask
A current listing price. Never counted as a sale.
Verified sold
A completed transaction that passed comp qualification.
Market reference
Third-party market pricing. Context, not a transaction.
Identity authority
Catalog or certification confirmation of what the card is.
