Questions about identifying autographs

Researching an unfamiliar signature? Use our free printable autograph research worksheet to keep photos, possible signers, and comparison notes together.

Can I identify an autograph from a photo?

A clear photo can help you research a possible signer. Autograph Identifier AI analyzes the selected image and suggests an identity, visual clues, and next steps. Compare the suggestion with documented examples and the history of your item. Read our photo identification guide for a practical checklist.

What should I photograph?

Keep the complete signature in focus and include enough of the ball, jersey, card, photograph, or document to show its context. Avoid reflections and do not edit or redraw the signature. Save a separate photo of the entire item for your own research.

Does identifying the signer prove an autograph is real?

No. Identifying a possible signer and establishing authenticity are different tasks. A copy can resemble a genuine signature. Use the app's observations as research leads and seek professional review for valuable items. Our authenticity guide explains the limitations.

How should I use an autograph value estimate?

Treat it as a starting point. Compare recent completed sales of similar items, considering condition, authentication, inscriptions, and provenance. An AI estimate is not a guaranteed sale price or an insurance appraisal. See the autograph value guide.

Where do I scan my autograph?

Scanning happens in the iOS app. Download Autograph Identifier AI on the App Store, then take or select a photo. Some features require a subscription; review the current options in the app.
