“The Steiner Seal Means It’s Real” is the motto of Steiner’s memorabilia division, and every product they sell delivers on that promise.   Steiner Sports broke into the sports business world in 1987 and since then, the company has established itself as a leading supplier of authentic, signed memorabilia. Steiner has exclusive autograph deals with a number of athletes including Derek Jeter, David Ortiz, Tony Hawk, Johnny Damon, Joe Torre, Tiki Barber, Paul O’Neil and Curt Schilling. Steiner acquires its signed merchandise through paid athlete signings. Each piece of memorabilia is inspected for quality. If a signed collectible passes this examination, it is affixed with a Steiner Sports hologram in the presence of a Steiner Sports representative. Once the tamper-proof holograms have been affixed to the product, it is catalogued and inventoried. A notarized affidavit is prepared and signed by both the athlete and a company representative. This document records the date and location of the signing and includes details about the specific item signed. This document is kept within the Steiner Sports flagship office. After this, a Steiner Sports Certificate of Authenticity is created for the item. The Steiner Sports Certificate of Authenticity is the size of a credit card and made of durable plastic. The text on the card reads, “This certificate is your assurance that the enclosed item of sports memorabilia has been personally signed by the state sports/celebrity/celebrities.” It also displays the Steiner logo, a facsimile signature of company president Brandon Steiner, and on the reverse include a hologram specific to the product as well as a description of the item and matching barcode. Some Steiner products, however, come with a card-stock COA rather than the card version. Once the COA has been issued, the item is secured within the Steiner Sports main office and is not handled again until purchase.
