Authenticating items to be sold on Amazon is a way of ensuring the value of the product. Authentication and grading is done by a third-party grading service and provides an impartial grading of the product. This is a feature sellers may use in order to guarantee potential buyers of the product quality. Often, once a product is authenticated, it is encased in an archival-quality holder to safeguard it and this is provided by the authenticating third-party service.
