Art collection appraisal: how to keep the cost under control

When a collection contains a large number of works, appraisal costs are not controlled by giving up the checks that make the valuation defensible, but by defining precisely the scope and the terms of the assignment.

The cost structure: time

Each work requires a rigorous methodological process: identification, direct examination, measurement, photographic documentation, research into comparable sales and a written, reasoned opinion of value. With dozens or hundreds of objects, the total number of hours can weigh disproportionately against the value of the minor works. For this reason, the essential preliminary step is to establish precisely what the client actually needs.

Defining the assignment in advance

Before the analysis begins, the following must be defined precisely:

The purpose of the appraisal: insurance cover, division of an inheritance, sale, collateral for a loan or a simple inventory. The purpose determines the type of value to be applied (for example fair market value or replacement value).
The valuation date: current or retrospective.
The scope and level of detail: the list of works to be appraised and the degree of analytical detail for each.
The location of the works: where every work is kept, including storage, vaults and secondary residences.

Different levels of analysis

Not every work requires the same depth of analysis:

Major works: they require specific market research and a fully reasoned value in the report.
Homogeneous works of modest value: serial or similar objects (such as multiples or prints by the same artist) can be grouped into homogeneous categories, with the valuation criteria stated in the appraisal. These methodological choices are agreed in advance in the engagement letter.

Working in phases

The assignment can be organised in stages: a first survey phase identifies the works that need closer technical study; the second sets their final valuation. In this way the client keeps full control over the scope and the cost of each phase.

What cannot be negotiated

For the appraisal to remain defensible, the examination of the works and the research into comparable sales cannot be waived. When direct examination is not possible for every work, the works not examined are valued on the basis of photographs and documentation, and the report says so. Leaving out the examination or the comparable sales exposes the appraisal to any challenge from third parties: a cheaper valuation that lacks methodological soundness ends up costing more.

Using existing inventories and records

Records, measurements and photographs already organised make it possible to reduce the time spent recording the works, and this is taken into account in the quote. However, an inventory does not replace the appraisal: the value remains the formal outcome of the appraiser's investigation and cannot consist of a simple ratification of values set by others.

Timing of the examination and logistics

If the works are to be moved or transferred, the direct examination and the check on the condition of the works must take place before they are packed, avoiding duplicated time and handling costs.
