Certificate of Authenticity
Certificate of Authenticity: What It Proves and What It Does Not
A card in the box is a claim by the seller. Here is what would have to be true for it to be proof.
What a certificate actually is
A certificate of authenticity is a written assertion by a seller or maker that a specific item is what it is said to be. On its own it is testimony, not evidence — and it is testimony from the party with the strongest interest in the answer.
The counterfeiter's position is simple: anyone able to reproduce the product to a tolerance a buyer accepts can certainly reproduce a printed card. Foil, embossing, sequential numbering and security paper raise the cost of forgery by a few pence each. They do not change the category.
What would make a certificate mean something
It must point outward. A certificate that only asserts is worthless; a certificate that carries a per-item identifier resolving to an independent register is a pointer to evidence.
The identifier must be unique to the one unit, and the register must notice re-use. If the same number is checked from six places in a month, the register must say so rather than confirm all six.
The register must be append-only. A record the issuing house can quietly amend after a dispute has no evidentiary weight, and any competent adversary will say so.
It must state its limits. A certificate that asserts origin, materials and maker is stronger than one that vaguely asserts genuineness, because narrow claims can be tested and broad ones cannot.
How to issue one properly
Assign a per-item identifier at the point of manufacture or intake, distinct from the SKU. Record it before the item ships, not when a buyer asks.
Print the identifier on the certificate and mark it on the item itself in a way that is hard to transfer. A certificate that can be moved to another unit authenticates the paper, not the object.
Publish a verification route that does not require the buyer to contact you, and log every check — the time, and roughly where from.
Say plainly on the face of it what is not attested: condition, valuation, fitness for a purpose, and anything that happened after the item left your hands.
What this house built
The Seal of Provenance issues the per-item mark, holds it in a register the issuing house cannot silently rewrite, and reports the verification history — including the same mark presented from places it should not be.
The paper in the box is then what paper should be: a pointer to the record, not a substitute for it.

The Seal of ProvenanceAsked of the house
- Is a certificate of authenticity legally binding?
- It is generally treated as a representation by the seller about the goods, which can matter in a dispute, but it is not proof in itself. Its practical weight comes from whether it points to an independent, verifiable record.
- Can counterfeiters fake a certificate of authenticity?
- Routinely. Anyone capable of reproducing the product can reproduce a printed card, including foil, embossing and sequential numbering. Security printing raises the cost of forgery slightly; it does not make the certificate evidence.
- What should a certificate of authenticity include?
- A per-item identifier separate from the SKU, the issuer and issue date, narrowly stated claims about origin, maker and materials, an independent verification route, and an explicit statement of what is not attested.
- Should the certificate or the item carry the identifier?
- Both, and the mark on the item should be hard to transfer. A certificate whose identifier exists only on the paper can be moved to a different unit, which authenticates the document rather than the object.
