How much does it cost to authenticate an autograph?

There is no single figure. Authentication is priced per item, and what you pay is driven by the declared value of the piece, the turnaround you choose, and how much documentation you want back. The one reliable way to get a number is to describe the specific item and ask — which, for entertainment material, Piece of the Past will do over the phone or by email.

What the fee is actually buying

Three things, in rough order of cost. Examiner time, which is the bulk of it — comparison work against exemplars cannot be rushed without becoming something else. Access to reference material, which is the part collectors cannot replicate at home. And the documentation itself, which means a serial-numbered letter plus a registry entry that has to be kept live for as long as that letter exists.

There is a fourth thing you are buying that never appears on the invoice: the guarantee standing behind the opinion. An examiner who backs their work with a refund policy has priced that risk into the fee, and that is entirely reasonable.

The variables that move the price

Declared value is usually the largest factor, because it sets both the examiner’s exposure and the level of documentation. Turnaround is the next — expedited tiers cost more everywhere. Then the physical nature of the item: a signed photograph is a simpler proposition than a costume, a prop, or a multi-page contract.

Finally, the paperwork you ask for. A sticker on the item and a fully illustrated letter of authenticity are different products at different prices. Add shipping and insurance in both directions, which people routinely forget when budgeting.

The cost you do not pay when it is authenticated at source

Buying from a dealer that authenticates what it sells changes the arithmetic, because there is no separate authentication invoice. At Piece of the Past the documentation is part of the purchase: a full letter of authenticity that describes and illustrates the piece, carries its own serial number, and can be checked in the company’s registry by scanning the QR code on the letter.

Those COAs are also full-force transferable, so the value of the paperwork is not spent the moment you decide to sell. That is worth weighing against the total cost of buying an undocumented piece elsewhere and then paying to have it examined — particularly since the second route also carries the risk of paying a fee to be told the item is wrong.

Deciding whether it is worth it at all

Authentication is insurance on a purchase price, so scale it accordingly. Paying a meaningful fee to authenticate a modest item rarely makes sense; skipping authentication on a four-figure purchase almost never does. The fee only looks expensive next to the price of the piece — it looks cheap next to the price of a convincing fake.

If a seller resists authentication on a valuable item, that resistance is itself information, and it is free.
