Everything you'd check before buying, done for you

Open a slab's listing on eBay and CrossCheck's panel does the legwork: no copying cert numbers, no squinting at borders. It reads ACE slabs today; other grading companies are on the roadmap.

A verdict on every slab it checks

For an ACE slab, whether it could get a PSA 10: PSA 10 candidate, Possible, Close call or Unlikely, with the reasons spelled out. Other crossings will get verdicts of their own.

Finds the slab's cert

From the listing's item specifics, else the QR code on the slab in the seller's photos, else the number printed on its label, checked against the grading company's record.

The grades at a glance

The card, set, number and grade, with Surface, Centering, Edges and Corners side by side, and a link to the cert on the grading company's site.

Centering, front and back

Both pairs of borders measured on the grading company's own images of the front and the back, at the worst point of an uneven border, the way graders judge it, each shown on a picture of the card.

Check it yourself

Not sure? Open the card in the Adjust editor: it walks you round the corners and middles of the card edge and the border at 500%, on the front and the back, and your lines decide your own verdict.

Right in the search results

Listings that have been checked show their verdict in eBay's search results, so the good ones stand out before you click.

Put the lines where you see them

Disagree with a line? Drag it. The editor takes you round the card one step at a time, the card edge's corners and middles first and then the border's, zoomed right in, with only the lines you're placing on show. Then flip to the back and do the same.

  • Corner dots that tilt a line, middle rings that bend it, locks, undo
  • A magnifier, a surface view and backgrounds that make card edges pop
  • Your lines decide your verdict, and help make the measuring better
