Custos Proof™by Custos Cards

Free · Check a Card

Buying a graded card? Check the cert first.

Type the cert number from the label. We send you straight to the grading company's own record, and to the registries where people report stolen cards.

Look up a cert

Type it from the slab or a photo you trust, not from a link the seller sent.

Match the photo, not just the number.

A real cert number can be put on a fake label. Compare the card, the grade and the label to the grader's own record and photos.

No record is a red flag.

If the grader has no card with that number, or the record shows a different card, stop and ask the seller why.

Check the stolen lists too.

Owners report stolen cards by cert number. A match there means walk away and tell the registry.

Selling one by mail?

Custos Proof gives you four timed photos, a bill of sale your buyer confirms, and a claim packet if anything goes wrong.

Worth too much to mail?

One vetted courier carries it by hand from pickup to delivery, in Las Vegas or coast to coast.
