How to Verify an SGA Autograph Is Authentic

Authenticity is everything in the memorabilia market. Here's what to look for:

• Hologram sticker — Every piece sold by Game Day Legends includes a tamper-evident hologram sticker that can be cross-referenced against our authentication database.
• Certificate of Authenticity (COA) — A COA from a reputable third party (such as Beckett Authentication or JSA) or directly from the signing event should accompany the item.
• Signing event provenance — The most reliable pieces are signed at controlled, witnessed events. We document each signing with photo and video evidence wherever possible.
