Looking For An Art Appraiser

You don’t need to be a museum curator to hire the right art appraiser, but you do need a plan. Whether you’re insuring a painting, settling an estate, donating a sculpture, or selling a collection, the quality of your appraisal directly affects your financial, legal, and tax outcomes. This guide explains what appraisers do (and don’t), the kinds of value you might need, how to verify credentials, what a defensible report looks like, and how to prepare so the process is efficient and accurate.

What an art appraiser does (and doesn’t)

An art appraiser is a trained personal property professional who develops an opinion of value for artworks and antiques. That value isn’t guesswork; it is supported by market data, a defined scope of work, and accepted methodology.

Key functions:

• Identify and describe the object: artist/maker, title, medium, dimensions, signature/marks, edition, date, provenance, and condition.
• Determine the relevant market(s): auction, retail gallery, dealer, or private sale, depending on the assignment.
• Research comparables: analyze recent sales of similar works, adjusted for differences in size, date, medium, edition, condition, and market timing.
• Develop and report a value conclusion: appropriate to the purpose (insurance, estate, donation, sale, equitable distribution, or collateral).

What appraisers don’t do:

• Authentication: Appraisers evaluate value; they do not certify authenticity. They may rely on catalogue raisonnés, artist foundations, scholars, or scientific testing, and will state assumptions or conditions regarding authenticity in the report.
• Restoration or conservation: They might note condition issues and recommend a conservator but won’t perform treatment.
• Contingent pricing: Ethical appraisers do not base fees on a percentage of value or on providing a predetermined number.

Terminology you’ll hear:

• Analysis vs. appraisal: “Valuation” or “opinion of value” often refer to the same work when performed to professional standards; a “price estimate” without inspection or methodology is not a formal appraisal.
• Desktop appraisal: Value developed from photos and documentation without in-person inspection. Useful in limited cases; not always suitable for insurance or IRS-related work.

Which value you need—and when

The right value definition depends on the assignment’s purpose. Using the wrong one can cost you money or cause compliance problems.

Common value types:

• Insurance (replacement value): The cost to replace the item with a comparable piece in the retail market, new or used, within a reasonable time. Typically highest, as it references retail/gallery asking prices and dealer inventories.
• Fair Market Value (FMV): The price a willing buyer and willing seller would agree to, neither under compulsion, with reasonable knowledge of relevant facts, in the most relevant market. Used for estate tax, noncash charitable contributions, and many equitable distributions. Generally lower than replacement value.
• Marketable Cash Value (net proceeds): The amount you would likely realize after typical selling expenses (commissions, fees, shipping). Useful when you plan to sell soon and want a realistic net figure.
• Orderly liquidation vs. forced liquidation: Values reflecting accelerated timelines or distressed conditions—relevant for bankruptcies or urgent sales.
• Retrospective value: Value as of a past date (e.g., date of death), often required for estates and some insurance claims.
• Prospective value: Value at a future effective date (e.g., anticipated sale season), rarer but sometimes used for planning.

Special cases:

• Donations: For significant noncash charitable contributions, FMV from a “qualified appraiser” is required, and additional documentation may apply. Expect strict adherence to appraisal standards.
• Restricted materials: Items containing ivory, rhinoceros horn, certain feathers, or archeological artifacts may face trade restrictions that materially affect value and salability.

Clarify the intended use and the effective date with the appraiser before any work begins. This drives the market selection, comparables, and report format.

Credentials, standards, and ethics

Appraisal credibility depends on the appraiser’s training, methodology, and independence.

What to look for:

• Professional education and USPAP compliance: In the United States, personal property appraisers should be up to date with the Uniform Standards of Professional Appraisal Practice (USPAP). Ask for the appraiser’s current USPAP completion date.
• Recognized appraisal organizations: Designations (such as Accredited or Certified) from reputable bodies indicate tested knowledge, supervised experience, and continuing education.
• Specialty fit: Choose someone experienced with your category—Old Masters are not the same as contemporary prints, photography, Asian art, Native American arts, design, or folk art. For mixed estates, a generalist can triage and bring in specialists as needed.
• Independence and ethics: The appraiser should not have a financial interest in the property’s disposition. They should not offer to buy the item they are appraising and should not charge a percentage of value.

Ask for:

• A current CV/resume with relevant coursework, publications, and case experience.
• Sample redacted reports (with client details removed) for the same type of assignment you need.
• A written engagement letter that defines scope, value type, intended use/user, fee structure, and timing.

Red flags:

• “Free appraisal if we can buy it” or contingent fees tied to value.
• Guaranteed outcomes (“I’ll get your painting accepted into the artist’s catalogue raisonné”).
• Refusal to provide a written report or a signed certification.
• No inspection for complex or high-value assignments when one is clearly needed.
• Overreliance on asking prices without analyzing realized sales.

Fees, scope, and reporting: how the work gets done

Every assignment begins with a defined scope of work. The clearer the scope, the more accurate the timeline and budget.

Common fee models:

• Hourly rate with a minimum: The most typical. Rates vary by region and specialty; complex research or travel time may bill differently.
• Flat fee per report or per item: More common for high-volume household contents or very straightforward items.
• Retainer or deposit: Often required to schedule site visits and begin research.

Never agree to a fee based on a percentage of value; it’s a conflict of interest.

Process overview:

1. Intake and triage: You provide photos, dimensions, signatures/labels, known provenance, previous appraisals, invoices, and your objective. The appraiser estimates scope and quotes fees.
2. On-site inspection (or desktop if appropriate): In-person inspection captures condition, construction, and details not visible in photos. The appraiser photographs, measures, and documents.
3. Research and analysis: The appraiser identifies comparable sales in the correct market and time frame, adjusts for differences, and considers market trends, condition, and provenance.
4. Value development: A reasoned conclusion is reached, sometimes as a range, consistent with the assignment.
5. Report delivery: You receive a written report with certification, methodology, and supporting data. Rush service may be available for an additional fee.

Timeline:

• Small assignments: 1–2 weeks after inspection.
• Complex/specialist work: 3–6 weeks or more, especially if archives or external experts are involved.
• Retrospective or IRS-related work can take longer due to documentation requirements.

What qualifies as a “report”:

• Full appraisal report: Complete narrative with all required elements for the intended use (e.g., insurance, estate, donation).
• Restricted appraisal report: Shorter format intended only for a single specified user and use. Not suitable for all purposes; ask whether it meets your needs before accepting a restricted format.

What a defensible appraisal report includes

A credible report is transparent, replicable, and compliant with professional standards. Ask the appraiser to confirm the report will include:

• Assignment definition: Intended use and user, property type, effective date, value definition, and relevant market.
• Object identification: Artist/maker, title, medium, dimensions, marks/signatures, edition number, date, literature and exhibition history, and provenance summary.
• Condition observations: Noting restorations, losses, craquelure, tears, stains, foxing, re-lining, repairs, or structural issues that may affect value.
• Photographs: Clear overall and detail images taken by the appraiser.
• Market analysis: Discussion of market level(s) considered (auction, retail, dealer), rationale for selection, and current market trends for the artist/category.
• Comparable sales: Citations of recent, relevant sales with dates, venues, lot numbers (if auction), and adjustments explained.
• Methodology: How the appraiser approached analysis and reconciliation of data; any extraordinary assumptions or hypothetical conditions.
• Value conclusion: A specific figure or range consistent with the assignment, stated per item and/or as a total.
• Limiting conditions and assumptions: Including any reliance on owner-supplied information and what was or wasn’t verified.
• Appraiser qualifications: Signature, certification statement, USPAP compliance statement, and CV.
• Glossary: Definitions of value terms used.
• For tax-related work: Additional statements to meet regulatory requirements, and retention of workfile materials.

If authentication is unresolved, the appraiser will either defer the assignment, proceed with a clearly stated assumption (with caution), or recommend specialist testing. That distinction should be explicit in the report.

Preparation and practical checklist for owners

A little preparation saves time and reduces your fee. Before the appraiser arrives—or before a desktop assignment—assemble as much information as you can.

Preparation tips:

• Don’t clean or repair: Well-intended cleaning can cause damage and alter value. Photograph items as-is.
• Gather provenance: Prior invoices, correspondence, exhibition catalogues, certificates, old labels on the verso, framing stickers, and prior appraisals.
• Photograph clearly: Front, back, signatures/marks, edges, labels, condition details. Include a ruler or tape for scale.
• Measure accurately: Height x width (and depth), unframed and framed if applicable; note mediums (e.g., oil on canvas, lithograph on paper).
• Group similar works: Series, editions, or sets should be documented together with edition numbers and portfolio titles.
• Access and safety: Clear pathways, ensure adequate light, and secure pets. For large works, plan assistance for safe handling.
• Legal considerations: If you’re part of an estate, trust, or divorce, confirm you have authority to order the appraisal and share documents.

Practical checklist:

• Define your purpose and deadline.
• Confirm the value type (replacement, FMV, liquidation, etc.).
• Verify the appraiser’s USPAP currency and specialty fit.
• Agree on scope, fee, and report format in writing.
• Provide provenance, invoices, and prior appraisals.
• Supply clear photos and precise measurements.
• Make the property accessible for inspection.
• Clarify any authenticity questions up front.
• Ask about turnaround and rush options.
• Request a redacted sample report for similar work.

FAQ:

• How do I choose between a generalist and a specialist? A trained generalist is ideal for mixed estates and household contents; they can identify outliers and bring in specialists. For a single high-value work or a niche category (e.g., post-war sculpture, Japanese prints), hire a specialist in that field.

• Can an online appraisal work for insurance? Some insurers accept desktop appraisals with adequate photos and documentation, especially for lower-value items. High-value, complex, or condition-sensitive works typically require in-person inspection. Always confirm with your insurer.

• What if I plan to sell soon—should I get an appraisal first? If you’re deciding where and how to sell, a consultation or market analysis may suffice. If you need a formal document for estate division, tax, or legal purposes, get a written appraisal. For consignment, some auction houses provide estimates; those are not appraisals but can inform your decision.

• Will restoration increase value? Sometimes. Stabilizing structural issues or removing discolored varnish can improve marketability, but restoration can also reduce value if invasive or poorly executed. Get a conservator’s estimate and discuss the impact with your appraiser before proceeding.

• Why do two appraisals differ? Different intended uses, effective dates, market selections, or condition opinions can produce different results. Appraisals should explain these variables; if both are credible and compliant, differences often trace back to purpose (replacement vs. FMV) or timing.

Closing thought: The best appraiser for you is one whose training fits your property, whose ethics are unimpeachable, and whose report you can hand to an insurer, executor, judge, or tax professional without hesitation. Define the assignment clearly, demand transparency, and prepare well—you’ll end up with a document that protects your interests and the art you care about.
