Pro · Graded cards

Look up a slab by its cert number

The cert number is printed on the label of every graded card. Type it in to see whether that number is on record, which card it was issued to, and what that grade has sold for in the last six months. A number on record does not prove the slab in your hand is genuine: compare the card to the record, and check it on the grading company's own site. Keeping it? Watch its price from the answer, at its own grade.
