PSA and PSA/DNA have combined services to offer you autographed baseball grading. Now your autographed baseballs, both single signed and multi-signed, can be authenticated by the industry's leading experts and graded by the best in the hobby. Each baseball is subjected to PSA/DNA's 4-step authentication process: from physical examination of the autograph by our experts to the detailed Letter of Authenticity. That's not all. Our experts will follow up with an evaluation on the condition of the baseball and autograph/s. Each item is assigned a grade for the signature/s, baseball, and an overall grade. This new service will not only provide you with the peace of mind about the authenticity but it will also provide you with the peace of mind about the quality.
