In order to ensure the accuracy of every grade they assign, PSA offers a cash-back policy for cards that remain in their tamper-evident holders.

This guarantee is fundamental to PSA’s concept of third-party grading and ensures that collectors can buy and sell with confidence.

In an industry rife with counterfeits, scams, and inexperienced graders, PSA card grading provides collectors with the security of knowing that their cards have been expertly authenticated and graded. PSA employs some of the most advanced technology in the collectibles industry in order to provide the best possible service for its customers.

In addition, PSA uses a standardized 10-point grading scale that is widely accepted by dealers and collectors alike. This scale provides a consistent and objective way to evaluate the condition of a card. To ensure unbiased grading, PSA graders are not given access to any customer information. This allows them to focus solely on the physical characteristics of the item being graded. With such rigorous standards in place, it is no wonder that PSA is considered the leader in collectible authentication and grading.
