Authenticity is our #1 priority at Signature Sports Marketing. We understand that counterfeit autographs are widespread in this industry, so we want to ensure that our customers know every item they purchase from us is 100% authentic. All of our memorabilia comes directly from private signings that we've conducted or from only the most reputable companies, such as Beckett Authentication Services, PSA/DNA and James Spence Authentication.
We guarantee and stand behind the authenticity of every item we sell. We have participated in thousands of athlete signings including Patrick Mahomes, Joe Montana, Drew Brees, Brett Favre, Emmitt Smith, Barry Sanders and Jim Brown. We issue our own SSM Certificate of Authenticity along with matching tamper-resistant holograms affixed to the signed item and certificate. Any item that comes from our reputable suppliers will also include its own certificate of authenticity and/or holograms. Every piece of memorabilia we sell is guaranteed to pass any third-party authentication process.
