A cert lookup can confirm whether the grading company returns a record for the number you entered. Compare that record's card description, grade, qualifiers, and available images with the card and holder you are considering.
A matching record does not independently authenticate the physical holder. Recheck every character, inspect the holder for visible alteration, and pause a purchase if a material detail conflicts. Ask for clearer photos or guidance from the grader or seller when the result is unclear.
Certification data is also not a value estimate. Use it as one input, then compare recent completed sales for the exact card, grade, label version, and marketplace before deciding what to pay.
Determine whether the card was graded by PSA, BGS, CGC, SGC, or TAG so you can use that company's official lookup route.
Copy the certification number exactly as shown on the holder. Some current labels also include a barcode or QR code, but the number is the comparison key.
Use the quick lookup tool above or visit the grading company’s website directly. Enter the cert number and review the returned record for the card description and grade.
Compare the card description, grade, qualifiers, and any available images with the holder. A material mismatch is a reason to pause and investigate further.
Look for visible gaps, damage, or signs of opening. A physical inspection adds context, but it also cannot make a final authentication determination by itself.
The same card graded by different companies often gets different numbers. Use this table to translate a PSA grade into its rough equivalent across PSA, BGS, CGC, SGC, and TAG.
| PSA | BGS | CGC | SGC | TAG (1000-pt) |
|---|---|---|---|---|
| PSA 10 | BGS 9.5–10 (Pristine needs 50/50) | CGC 9.5–10 Pristine | SGC 10 Pristine | 950–1000 |
| PSA 9 | BGS 9 / 9.5 | CGC 9 / 9.5 | SGC 9 / 9.5 | 875–949 |
| PSA 8 | BGS 8 / 8.5 | CGC 8.5 | SGC 8.5 | 800–874 |
| PSA 7 | BGS 7 / 7.5 | CGC 7.5 | SGC 8 | 700–799 |
| PSA 6 | BGS 6 / 6.5 | CGC 7 | SGC 7 | 600–699 |
| PSA 5 | BGS 5 / 5.5 | CGC 6 | SGC 6 | 500–599 |
