Who signed it sets the base. What was signed, whether it's authenticated, and whether it's made out to you then multiply that up or down — and two of those three surprise most people.
Estimated value
$32 – $320
$80–$800 base, then ×0.40 for the format, paperwork and inscription.
Get it authenticated and it's worth $80 – $800
PSA, JSA and Beckett charge roughly $20 to $50 for a straightforward signature. On anything above about $100 that fee pays for itself several times over — an unauthenticated autograph sells for a third to a half of the same item with a slab.
A range, not an appraisal. Who signed it swamps everything else, and within any tier a specific name can be worth ten times another. Look up sold listings for that exact person and format before you set a price.
Can't make out the signature?
Half of autograph collecting is working out whose name that scrawl is. Photograph it and the AI compares the letterforms against known exemplars.
Identify the signatureWhat moves an autograph's price
Two of these surprise people. A certificate from a dealer nobody has heard of is worth barely more than no certificate at all. And having your own name on it — the thing that felt special when you got it signed — takes about a third off, because the next buyer isn't called Jack.
| Factor | Option | Effect | Why |
|---|---|---|---|
| What was signed | Cut signature or album page | ×0.6 | Just the signature, no context. The cheapest way to own one. |
| What was signed | Signed photo | ×1 | The benchmark every price guide quotes. |
| What was signed | Signed book | ×1.1 | Slight premium over a photo if it's a first edition. |
| What was signed | Ball, jersey or equipment | ×1.8 | Displays well and is harder to fake. On a baseball, the sweet spot beats a side panel. |
| What was signed | Handwritten letter or document | ×2.5 | Content in their own hand. The strongest format there is. |
| Authentication | None | ×0.4 | No paperwork. Buyers assume the worst and bid accordingly. |
| Authentication | Dealer certificate | ×0.6 | A COA from a shop nobody has heard of adds very little. |
| Authentication | PSA, JSA or Beckett | ×1 | The three that auction houses and eBay filters actually recognise. |
| What it says | Signature only | ×1 | What most collectors want. |
| What it says | Personalised ("To Jack") | ×0.65 | Counterintuitive but consistent: a stranger's name on it cuts the value. |
| What it says | Inscribed with a quote or stat | ×1.15 | "HOF 95" or a signature line adds to it, unlike a personalisation. |
What the very best have sold for
For scale. Note that four of the five are not signed photos — they are documents and objects, which is the format premium doing its work at the top of the market too.
| Item | Sold for |
|---|---|
| George Washington — his annotated copy of the Constitution and Bill of Rights | $9,800,000 |
| Abraham Lincoln — signature on the Emancipation Proclamation | $3,700,000 |
| Babe Ruth — signed baseball (2012) | $388,375 |
| Marilyn Monroe & Joe DiMaggio — signed baseball (2021) | $384,000 |
| Marilyn Monroe — photo inscribed "I love you Joe" to DiMaggio | $300,000 |

Why knowing your Autographs value matters
The autograph market is uniquely susceptible to forgery, with some estimates suggesting a significant percentage of autographs in circulation are not genuine. This makes authentication the single most important factor in autograph valuation. Beyond authenticity, the signer's fame, the item signed, the signature's quality, and inscriptions all affect value. A hastily scrawled signature on a torn piece of paper from a major historical figure is still valuable, but the same signature on a relevant document or photograph is worth much more. Value Identifier provides both identification and authenticity risk assessment.

Key factors that determine Autographs value
Signer Significance
Presidential signatures, entertainment legends, sports Hall of Famers, and historical figures command the widest ranges and highest premiums.
Authentication
Third-party authentication (PSA/DNA, JSA, Beckett) dramatically increases value and saleability compared to unauthenticated signatures.
Medium & Item
Signatures on relevant items (a musician's guitar, an author's book, a baseball player's baseball) are valued higher than signatures on plain paper.
Signature Quality
Bold, complete signatures are preferred over abbreviated, faded, or smudged examples. Legibility and visual appeal matter to collectors.
Rarity & Supply
Autographs from individuals who rarely signed or who are deceased command premiums over prolific signers whose signatures are abundant.
Tips for scanning your Autographs
Photograph the signature close-up in sharp focus, ensuring the complete autograph is visible without shadows or obstructions.
Include the full item in a separate photo. The context (book, photograph, baseball, document) is important for accurate valuation.
Capture any authentication stickers, COA cards, or certificate documents that accompany the autographed item.
Use even, non-reflective lighting to ensure ink color and signature details are accurately represented for AI analysis.
Autographs market overview
The autograph market has been transformed by third-party authentication services that provide standardized verification. Authenticated autographs trade with significantly more confidence and at premium prices compared to unauthenticated examples. The market for historical and political signatures remains strong among institutional and serious private collectors, while sports and entertainment autographs have a broader consumer base.
Autographs valuation FAQ
Can Value Identifier authenticate autographs?+
The AI compares signature characteristics against known exemplars for many public figures, flagging inconsistencies that may indicate forgery. However, definitive authentication requires professional forensic examination by services like PSA/DNA or JSA.
Does the item matter for autograph value?+
Yes, significantly. A signature on a relevant item (player's jersey, author's first edition, musician's record) is typically worth 2-5x more than the same autograph on a plain index card or photograph.
How much does authentication add to value?+
Authenticated autographs typically sell for 2-10x more than unauthenticated equivalents, as authentication eliminates forgery risk that dominates buyer concerns in this market.
Are secretarial signatures valuable?+
Secretarial (secretary-signed) autographs have minimal collector value, as they were not personally signed by the individual. Value Identifier's analysis helps flag signatures that may be secretarial based on known patterns.
