Steiner Sports Authenticity Guarantee

Each and every hand-signed collectible that carries a tamper-proof hologram is witnessed by a Steiner Sports representative. Once the collectibles have been autographed, they are catalogued and inventoried.

A notarized affidavit is prepared and signed by the athlete and a Steiner Sports representative. The notarized affidavit records the date and location of the signing and also details the items that were signed by the specified athlete. This document is then secured within the Steiner Sports main offices.

Each hand-signed collectible is examined for quality and signature condition. If the collectible meets the Steiner Sports standard of excellence a tamper-proof Steiner Sports hologram is affixed to the product.

Once the hand-signed collectible has passed the steps listed above, a Steiner Sports Certificate of Authenticity is created for the collectible. The collectible is then sealed and stored within our main office and is not handled until it is delivered to a sports collectible enthusiast.
