How Much Is My Autograph Worth?

Every valuation carries a silent assumption: that the signature is genuine. Remove that assumption and the figure does not shrink, it disappears. A forged signature on a genuine period photograph is worth what the photograph is worth without it, and usually less, because a knowledgeable buyer now has to explain the ink to whoever they sell it to next.

So the first move is not a price search. It is working out what you are holding: an original signature, a preprint, a secretarial, an autopen, or a photograph of a signature. How to tell if an autograph is real covers the checks you can make yourself in ten minutes with a lamp and a magnifier.

Collectors tend to assume fame does most of the work. It does less than you would think. Two signatures from the same person, in the same decade, can sit an order of magnitude apart because of what follows.

The hand

Not how famous the person was, but how much of their signature exists. Someone who died before the convention circuit began left a fixed supply. Someone who signed at shows for twenty years did not, however large their name is.

What it is on

A signature on a blank card, a studio photograph, a script, a contract or a screen-used prop are four different objects with four different markets. Format sets the ceiling before anything else is considered.

Condition

Ink strength first, then surface. A signature that has ghosted into a gloss photograph is a heavy deduction and the most common way a surviving piece loses most of its value. Trimming, tape, fading and restoration all bite.

Provenance

What you can show about where it came from. A named source who can be found and asked is worth real money on a heavily faked name, and almost nothing on a name nobody bothers to fake.

What makes an autograph valuable takes those four apart in detail. The firm's own piece on the top three factors to consider is the short version from the selling side.

When someone says "a signed photo of X is worth Y", they are quoting one point on a curve. The same signer, in the same year, spans a range like this:

• Signed in character, on a recognisable image from the role people know the person for — the top of the range.
• Signed on a generic modern headshot bought in bulk for a show table — the bottom of it.
• Inscribed to a stranger — almost always a deduction, because the next buyer is not that stranger.
• Inscribed to a documented colleague, co-star or family member — often a premium over a clean signature, because the inscription is now provenance.
• Signed on production paperwork rather than on a photograph bought for the purpose — a different market again, and usually a stronger one.

Comparable sales are the only honest input an owner has access to on their own, but they are easy to misread. The discipline is narrow:

• Use sold prices, never asking prices. Anyone can list anything at any number, and unsold listings sit at the top of search results for years.
• Match the format before you match the name. A signed index card is not a comparable for a signed 8x10.
• Read the total, not the hammer. Auction results quoted without the buyer's premium understate what the buyer actually paid.
• Check the date. A death, a franchise revival, a documentary or an anniversary can move a name in a fortnight and leave last year's results stranded.
• Discount results you cannot see the item in. A comparable without photographs is a rumour.

Retail value and what lands in your account are different numbers, and the gap is the service you are buying. There is no version of this where the fastest route also pays the most.

Outright purchase

A dealer buys the piece from you today. Lowest headline figure, no fees, no waiting, no risk that it fails to sell. For most single pieces this is the sane option.

Consignment

The dealer sells it for you and takes a percentage. Higher expected result, slower, and your money arrives after the sale rather than before it.

Auction

The room decides. The right piece in the right sale beats every other route; the wrong piece in the same sale sells for less than a dealer would have paid you.

Selling it yourself

You keep the margin and you inherit the work: photography, description, postage, disputes and the buyer who claims a genuine piece failed someone's opinion. Fine for a single common signature, punishing for an estate.

Where to sell an autograph collection works through which of those fits which kind of material.

A conversational figure is enough to decide whether to sell. It is not enough for an insurer, an executor or a court. A written appraisal states a defined value — replacement, fair market or forced sale — as of a date, by someone who can defend it.

• Insurance scheduling, where an unvalued collection is an uninsured one.
• Estates and probate, where the figure has to survive scrutiny by people with opposing interests.
• Division of property, for the same reason.
• Donation, where the documentation requirements are stricter than most owners expect.
