We strongly encourage accessing our database to verify and authenticate the validity of any and all certification numbers. Verification of certification numbers on the Hero Grader certification database does not guarantee the elimination of risk or fraud through unscrupulous individuals. If you did not receive the book directly from Hero Grader, the best way to confirm the authenticity of one of our graded books is to compare the database scan to the book you may be buying or selling through high resolution scans or in person comparison.
