What a Valuation Report Includes

A professional valuation report is not simply an inventory with prices beside it. It is a dated, reasoned and accountable opinion that should identify exactly what was valued, why it was valued, which market and definition of value were used, what evidence was examined, what assumptions or limitations applied and how the valuer reached the conclusion.

The format varies by jurisdiction, professional standard, collecting field and intended use, but a defensible report should allow an informed reader to follow the assignment from instruction to evidence, from evidence to reasoning and from reasoning to conclusion. Its quality lies not in its length or visual polish, but in whether it makes those links explicit.

Collector scenario

Two reports, one collection and two completely different answers

A collector receives one document that lists a rare boxed game at $8,000 and another that concludes $4,500. At first glance, one valuer appears simply to be wrong. On inspection, the first figure is a retail replacement value including tax and specialist sourcing costs for insurance. The second is an estimated auction hammer price for sale planning, before buyer's premium and seller's commission.

The reports do not contradict each other; they answer different questions. A strong report makes that difference impossible to miss. A weak report leaves the collector comparing numbers that were never intended to be comparable.

The report as an argument

Six layers every serious valuation report should reveal

The most useful way to read a report is not as a sequence of headings, but as a chain of accountability. Each layer should support the next.

Assignment

Why the report exists

The report should identify the client, intended users, purpose, ownership interest, basis of value, relevant market and effective date. These terms define the question the valuer was asked to answer.

Subject property

What was actually valued

Each material object or group should be described precisely enough to distinguish it from similar examples, including variant, condition, completeness, authenticity status and supporting provenance where relevant.

Evidence

What information supports the opinion

The report should distinguish direct inspection, verified records, client-supplied information, assumptions and comparable market evidence rather than blending them into one undifferentiated account.

Reasoning

How the conclusion was reached

A professional report explains the market selected, methodology used, important comparables, adjustments, weighting and uncertainty. It should reveal the route from evidence to conclusion.

Conclusion

What value was concluded

The final amount or range should be expressed in a named currency, under a defined basis of value, at a stated date, with clear treatment of tax, premiums, fees and other transaction costs.

Accountability

Who stands behind the report

The responsible valuer should be named, qualified, independent, signed and accountable for the work, with conflicts, assistance, departures and professional standards disclosed.

The collector's central test

Could another competent reader understand what the valuer was asked to do, identify the objects, see which information was trusted, follow the analysis and understand exactly what the final figure represents? If not, the document may be a useful informal opinion, but it is not yet a fully transparent professional report.

Opening framework

The report must first define the assignment

Before any item description or price appears, the report should establish the legal, professional and market context in which the opinion is being given.

Identify the report, client and responsible valuer

The title page or opening section normally identifies the report, the client, the owner where different, the collection or property, the responsible valuer, the valuer's firm and contact details, and any report or case reference. It may also state confidentiality or circulation restrictions.

The named individual matters. A firm can provide administration and institutional standing, but the report should still reveal who performed or supervised the valuation, their qualifications, specialist experience and status as an internal or external valuer.

State who may rely on the report

A report should distinguish the person who commissioned the work from the owner of the objects and from any intended third-party users. An insurer, solicitor, executor, tax authority, lender or court may need to rely on the report, while unrelated third parties may be expressly excluded.

This is not administrative boilerplate. A valuation prepared for one purpose is not automatically fit for another, and unrestricted circulation may expose both collector and valuer to uses that were never investigated or priced into the assignment.

Define purpose, intended use and ownership interest

The report should say exactly why the valuation was prepared: insurance scheduling, loss, probate, tax, donation, matrimonial division, secured lending, sale planning, collection management, litigation or another named use. Phrases such as “for valuation purposes” are too vague to establish the correct market or value basis.

It should also identify whether the whole object, a fractional interest, a partnership interest, a grouped collection or some other ownership interest was valued.

Name and define the basis of value

Market value, fair market value, retail replacement value, auction value, orderly liquidation value and forced-sale value are not interchangeable labels. The report should identify the basis, give or cite its definition and explain why it is appropriate to the purpose.

A professional report should never rely on the word “value” alone. The definition controls the assumed parties, market, level of compulsion, time available, transaction setting and treatment of costs.

Myth

A collectible has one true value, and a good valuer's task is to discover that single number.

Reality

A collectible can support several defensible conclusions because insurance replacement, open-market exchange, auction sale and liquidation each model a different transaction.

Dates

Three dates that should not be collapsed into one

Collectors often look only at the date on the cover. A formal report may need to distinguish three separate moments.

Inspection date

When the object or supplied material was examined. This records the condition and information available to the valuer at the time of inspection.

Effective valuation date

The date to which the opinion of value applies. For probate, tax, litigation or retrospective assignments, this may be earlier than both inspection and report issue.

Report date

When the report was completed and issued. Market events between the effective date and report date may need to be disclosed if they affect interpretation.

Market definition

The report should identify the market, not merely cite prices

The same collectible may trade through specialist dealers, major auctions, regional auctions, private collector networks, graded markets or general online platforms. Those markets are not economically identical.

A useful market section should explain whether the conclusion reflects specialist dealer retail, auction hammer, premium-inclusive buyer cost, seller net proceeds, private treaty, wholesale or another level. It should also identify the geographic or sector context where material.

Asking price versus achieved sale

Hammer price versus buyer's total cost

Gross sale price versus seller's net proceeds

Graded market versus ungraded market

Specialist market versus general marketplace

Individual sale versus collection block sale

Scope of work

A report must explain what the valuer did - and did not do

Scope is where the document defines the extent of inspection, research and testing. Restrictions are not automatically defects, but undisclosed restrictions are.

Inspection and access

In-person, remote or desktop assignment
Inspection dates and locations
Objects, groups or sample items examined
Whether frames, packaging, cases or holders were opened
Whether internal or concealed components were accessible
Measurements, weights or functional checks undertaken

Research and specialist work

Databases, catalogues and archives consulted
Extent of comparable-market research
Authentication investigated or assumed
Scientific or technical testing undertaken
External experts or assistants involved
Legal title, export or ownership issues excluded

Information architecture

The report should separate evidence from assumption

One of the clearest signs of professional discipline is the way the report classifies information.

Observed

Directly examined facts

Marks, dimensions, packaging, visible wear, missing components, holder details and other characteristics the valuer personally inspected or measured.

Verified

Externally corroborated facts

Catalogue references, grading records, auction archives, maker databases, invoices, archival correspondence or provenance documents checked against reliable sources.

Supplied

Information accepted from others

Statements, photographs, certificates or histories supplied by the owner, client or third party but not independently confirmed by the valuer.

Assumed

Conditions adopted to complete the assignment

Matters such as lawful title, genuineness of a signature, contents of sealed packaging or absence of concealed restoration where verification was not possible.

Assumptions that deserve prominence

Material assumptions should not disappear into generic terms at the back of the document. They may include lawful title, genuineness of a signature, untampered grading holders, contents of sealed packaging, transferability across borders, absence of concealed defects or an assumed method of sale.

A special assumption or hypothetical condition goes further by asking the valuer to model a circumstance that differs from known facts or does not yet exist, such as valuing an item as though disputed authenticity had been confirmed. Because changing the assumption can change the value radically, it should be explicit and close to the conclusion it affects.

Object schedule

Each collectible must be identifiable as the thing that was valued

A professional report does not need the same level of detail for every low-value object, but significant items should be described so that they cannot be confused with materially different examples.

•Recognised title or object name

•Maker, artist, designer, publisher or manufacturer

•Franchise, series, product line or edition

•Date, period, country or region

•Materials, technique, dimensions and weight

•Model, catalogue, serial or reference number

•Printing, impression, state, language or variant

•Packaging form and original accessories

•Signatures, inscriptions, stamps and labels

•Certification, grading or inventory number

•Modifications, restoration and distinguishing features

•Ownership interest and report schedule number

Variant precision is particularly important for mass-produced collectibles. Copyright text, logo placement, print run, mould, box style, colour, regional code, insert, card back or manufacturing error may separate an ordinary issue from a scarce and materially more valuable one.

Condition judgement

Condition, completeness, originality and authenticity are separate axes

A single grade can conceal several different questions. Strong reports expose the attributes that actually influence market comparison.

Physical condition

Wear, fading, creasing, corrosion, cracks, stains, repairs, restoration, refinishing, contamination, concealed defects and operational status where relevant.

Completeness

Presence of original inserts, accessories, components, packaging, documentation and matched parts. A visually pristine item may still be materially incomplete.

Originality and alteration

Replacement pieces, reproduction parts, recolouring, trimming, rebacking, resealing, relabelling, customisation or other changes that affect identity and market acceptance.

Authentication status

Whether authenticity was established, attributed, assumed, supported by a named authority, left inconclusive or questioned. Valuation should not imply authentication work that was not performed.

Myth

A third-party grade or sealed holder eliminates the need for the valuation report to discuss condition and identification.

Reality

The report should still identify the grading company, grade and certification number, consider whether the holder matches the object and appears untampered with, and explain the limits of reliance.

Provenance and images

Supporting identity beyond the object description

Provenance

Where relevant, the report should record previous owners, acquisition history, auction or dealer appearances, exhibition or publication references, collection labels and documentary support.

It should distinguish documented, partly documented, reported and unknown provenance. Family history can be valuable evidence, but it should not be presented as established fact when it remains oral or unsupported.

Photographs

Images should be cross-referenced to the report inventory and should show the views needed to identify the object: front, reverse, packaging, labels, numbers, signatures, damage, repairs, variant details and components.

Photographs strengthen identification but do not replace written description. A picture may not reveal dimensions, hidden repairs, completeness or the exact market assumptions applied.

Valuation analysis

The methodology should show how evidence became a conclusion

For most collectibles, the primary approach is market comparison. The report should reveal the sequence rather than merely state that comparables were considered.

Define the relevant market

Select the market consistent with the purpose, basis of value and likely participants.

Find relevant evidence

Locate completed sales, reliable private evidence, appropriate offerings and other market indicators.

Test reliability

Assess recency, source quality, transaction status, price components and whether the evidence is genuinely comparable.

Compare material attributes

Consider identity, edition, rarity, condition, completeness, authenticity, provenance and sale circumstances.

Adjust or weight

Explain why some evidence deserves more influence and why other apparently similar results were rejected.

Reconcile

Bring the evidence into a final point value, range or set of conclusions under the stated basis and date.

Comparable evidence that deserves challenge

Active listings treated as completed transactions
Hammer prices mixed with premium-inclusive prices
Restored and unrestored examples compared without adjustment
Different variants grouped because the titles look similar
Outlier sales used without explanation
Old sales imported without considering market movement or currency
Different grading systems treated as directly equivalent
Collection-lot prices divided mechanically across dissimilar items

Conclusion

The final number must say what it includes

A clear conclusion is more than a currency figure. It is a figure attached to a date, value basis, market, ownership interest and set of cost assumptions.

The report may conclude a point value, a defensible range, item-by-item values, group values, a collection total or separate conclusions under different bases. It should state whether a collection total is simply the sum of individual values or incorporates a premium or discount for selling together.

It should also explain the treatment of currency conversion, VAT or sales tax, customs duties, buyer's premium, seller's commission, shipping, insurance, certification, restoration and other costs. Two figures can appear different simply because one is gross and the other net.

Where the evidence is weak or volatile, the report should discuss material uncertainty rather than conceal it behind false precision. A range can be more honest than an exact figure when the buyer pool is narrow, comparables are scarce or authenticity remains unresolved.

Professional accountability

Certification, independence and limiting conditions

Certification

The valuer normally confirms that the factual statements are accurate to the best of their knowledge, the analysis is independent, assistance is disclosed and compensation was not contingent on a predetermined result.

Standards

The report may cite RICS, IVS, USPAP, ASA, ISA, AAA, a statutory regime or court rules. It should claim only standards that genuinely apply and disclose material departures.

Limitations

Legitimate disclaimers define reliance, title, authenticity, latent defects, future market change and circulation. They cannot repair inadequate inspection, weak research or unsupported reasoning.

Purpose-specific reporting

The core structure remains, but the emphasis changes

The intended use often determines which report sections require the greatest depth and which formal declarations or statutory elements must be added.

Insurance

Replacement-focused reporting

Usually requires individual scheduling of significant objects, photographs, a stated replacement market, treatment of tax and transaction costs, and clarity that the result is not an estimate of auction proceeds.

Probate and estate

A legally anchored date and basis

Often requires a statutory or open-market definition, the date of death, ownership shares, evidence close to that date and compliance with the relevant tax authority or estate process.

Tax and donation

Enhanced qualification and evidence

May impose formal appraiser qualifications, declarations, acquisition disclosures, prescribed wording, detailed comparable analysis and jurisdiction-specific forms.

Litigation

Transparent expert reasoning

Usually demands a clear separation of fact, assumption and expert opinion; disclosure of instructions and materials considered; full reasoning; and compliance with procedural rules and statements of truth.

Sale planning

Advice beyond the value conclusion

May include venue, lotting, reserve, certification, conservation, timing, likely costs and liquidity, but this commercial advice should remain distinct from the formal valuation basis.

Specialist threshold

When a general report is not enough

A collector should consider additional specialist input when value depends on disputed authenticity, technically complex restoration, a rare variant with poor documentation, sealed contents, hazardous materials, legal restrictions, culturally sensitive material or a market so narrow that one or two private transactions dominate the evidence.

The professional response is not to pretend uncertainty has disappeared. It is to identify the gap, obtain the necessary expertise where proportionate and explain what remains unresolved.

Collector review

A practical checklist for reading the finished report

The collector does not need to reproduce the valuer's work, but should be able to test whether the report is complete, coherent and fit for its intended use.

Instruction and use

Client, owner and intended users
Purpose and intended use
Ownership interest valued
Restrictions on reliance, publication or circulation
Effective valuation date, inspection date and report date

Applicable professional or statutory standard

Object-level evidence

Sufficient identification of each significant collectible
Variant, edition, printing, state or issue where material
Condition and completeness stated separately

Information relied upon and assumptions
Methodology and comparable evidence
Market commentary where relevant
Item, group and collection conclusions
Material uncertainty and limiting conditions
Signed certification and valuer declaration

Diagnostic cards

Common warning signs

Any single issue may be explainable, but clusters of these signs justify questions before the report is relied upon.

A price without a defined value basis

A number labelled simply as 'value' may be unusable. Insurance replacement, fair market, auction, liquidation and seller-net figures answer different questions.

Descriptions that cannot identify the object

Generic wording such as 'old comic', 'boxed game' or 'silver coin' prevents the report from proving which object was valued and which market evidence is relevant.

Condition reduced to an unexplained adjective

Words such as excellent, fine or mint are unreliable unless the market convention is identified and the underlying defects, repairs and completeness are recorded.

No visible reasoning

A report that shows a photograph and a figure but no market, evidence, comparables or reconciliation is closer to an informal price opinion than a defensible valuation.

Unsupported claims of authenticity

The report should explain whether authenticity was independently investigated, assumed, accepted from a certificate or determined by a recognised specialist.

Conflicted commercial incentives

Extra caution is required where the person assigning the value also offers to buy the object, receives a contingent fee or benefits from a predetermined conclusion.

What a good report should allow the reader to answer

Who instructed and prepared the valuation?
Who may rely on it, and for what purpose?
What exact objects and ownership interests were valued?
Which basis of value and market were used?
On what date does the opinion apply?
What was physically inspected and what was supplied remotely?
Which information was observed, verified, supplied or assumed?
How were condition, completeness, authenticity and provenance handled?
Which market evidence was accepted or rejected, and why?
How was the final value reconciled?
Which costs, taxes, premiums and commissions are included?
What uncertainty or limitation affects reliance?
Is the report signed, independent and professionally accountable?

Key takeaways

A professional valuation report documents an assignment and a chain of reasoning, not merely a price.
The purpose, basis of value, relevant market and effective date define what the number means.
Object identification, condition, completeness, authenticity and provenance should be specific enough to support the market comparison.
Observed facts, verified evidence, supplied information and assumptions should be distinguishable.
Comparables require interpretation; similar titles or visible asking prices are not automatically reliable evidence.
Material uncertainty should be explained rather than hidden behind false precision.
The report should identify the responsible valuer, disclose conflicts and assistance, state applicable standards and include a signed certification.
A report prepared for one purpose should not be reused for another without checking whether its basis, date, scope and intended users remain appropriate.
