Authentication

The signature is authenticated by JSA (James Spence Authentication), an independent third-party authenticator.

Some of our pieces also carry a Custom Authentics hologram serial as a second record alongside the certification. Learn about serial verification.

Common questions

Where is the signature? On the jersey, in black ink. Placement varies from piece to piece because each jersey is signed individually.

Will my piece look exactly like the image? The image is a preview of the finished display, since each piece is framed after you order. The two player photographs vary from piece to piece, as do the signature placement and certification serial.

Why does it take 2 to 3 weeks? The signature is authenticated and certified before we do anything. Only then is the piece framed by hand and packed with its certificate.

Can I return it? No. All sales are final. If your piece arrives damaged in transit, contact us within 48 hours of delivery. Full details are on our shipping and returns page.
