Pre-Columbian art appraisal: what you need and why

Do I need an appraisal or a buyer's offer?

Start with the question you need answered. If you want to know whether a buyer is interested in a jar, a first opinion and an offer may be enough. If someone needs a written valuation for insurance or an estate, ask what kind of report they require before commissioning one. The intended reader and use should be agreed at the beginning.

An identification names what a piece appears to be. Authentication considers whether that attribution is supported by the object and its evidence. An appraisal estimates value using a stated basis. These tasks can inform one another, but a document headed 'appraisal' does not automatically include an independent investigation of authenticity. Ask what has actually been examined and what is assumed.

Why can insurance value differ from sale value?

An insurance appraisal commonly considers the cost of replacing a piece with a comparable example. A valuation for a possible sale considers a different question: what the piece might achieve in a defined market. An estate assignment also needs its intended use and valuation date clearly specified. There is no universal figure that answers every purpose.

This distinction explains why a buyer's offer need not match an insurance appraisal. Neither document can be assessed sensibly without knowing its purpose, date, market and assumptions. When comparing opinions, compare those foundations first. What moves pottery value sets out the object qualities behind a valuation; how we value concerns a buyer's offer.

What does a pre-Columbian art appraiser look at?

A specialist needs to identify the object closely enough to choose meaningful comparisons. 'Ancient pottery' is too broad a category: form, material, likely culture, period, condition and quality all need attention. A comparison should explain similarities and differences, rather than rely on a shared animal subject or a similar silhouette.

• Attribution. What supports the proposed culture, period and kind of object, and how confident is the identification? An uncertain attribution should remain visible in the report.
• Originality and condition. Which surfaces and parts are original? Repairs, added sections and repainting can change both the appearance and the comparison with other examples.
• Quality and subject. Modelling, painting, proportions and the particular subject help distinguish a routine example from an accomplished one within the same kind of work.
• History and supporting evidence. Earlier collections, publications, sale records and test reports should be connected to the actual piece, rather than simply repeated from an old description.
• Market evidence. The report should explain why its comparisons suit the purpose. Completed sales are relevant to a sale-market analysis; replacement research may also consider current retail offers.

How do I choose an appraiser near me?

For an appraisal of pre-Columbian artifacts, subject experience matters alongside appraisal training. Ask whether the person regularly evaluates the particular material and culture involved. Someone who knows later household ceramics may be an excellent antique appraiser without being the right person for an ancient painted vessel. A nearby generalist may be able to bring in a suitable specialist.

Professional directories, including those of the Appraisers Association of America and the International Society of Appraisers, are starting points for checking specialties and credentials. Check the person's current designation, training and relevant experience rather than treating a membership badge as an answer to every question. Ask whether an in-person examination is included and what limits apply if the work is based on photographs.

Agree the scope and fee basis in advance. Choose a fee arrangement independent of the appraised value, such as an agreed project or hourly fee. Ask about any interest in buying the piece and how that affects the assignment.

What should I prepare for a pottery appraisal?

Give each piece an identifier and use it on the photographs and document list. This is especially useful when several similar vessels belong to an estate. Separate what a document says from what the family remembers, and make uncertainty explicit. 'Possibly the jar in this photograph' is more useful than an unsupported identification presented as fact.

• Photographs of the whole piece from several views, including the base, rim, interior and any visible marks, labels, damage, repairs or later paint.
• Dimensions and the material you believe it is made from, clearly distinguished from an expert identification if none has been made.
• Receipts, earlier appraisals, correspondence, old photographs, catalogue entries and laboratory reports, including all pages and any identifying images.
• The purpose of the report, its intended reader and the date at which value is needed.
• A short account of how the piece came into the collection and which details remain unconfirmed.

What should the written report explain?

Look for a description and photographs that identify the piece, the intended use, the effective valuation date, the kind of value estimated and the research supporting it. The appraiser should explain the examination, relevant condition, comparisons and limits. Ask for an explanation of specialist terms rather than accepting a conclusion you cannot interpret.

A laboratory report can support an age assessment of fired clay, but it is not itself a valuation. An earlier appraisal can be useful background, but its attribution and market evidence may need reconsideration. How pottery authentication works and what provenance means explain these separate kinds of evidence.

If you are thinking about selling

We buy single pieces and whole collections; we do not sell. A first opinion comes from clear photographs. Send photographs and what you know for a reply within two working days, with an offer in writing or a plain statement of what we cannot take. There is no fee and no obligation. That is a buying enquiry, distinct from commissioning an independent appraisal.
