What Sothebys Appraises—and What They Don’t

Sotheby’s focuses on fine and decorative arts and high-value collectibles, supported by specialist departments with deep category knowledge and sales data across global markets. Common categories include:

• Fine art: Old Masters, Impressionist & Modern, Post-War & Contemporary, American art, Latin American art, Asian art, African & Oceanic art, Islamic art, and more.
• Photographs, prints, and multiples: From early processes to contemporary editions.
• Decorative arts and design: Furniture, silver, ceramics, tapestries, design objects.
• Jewelry and watches: Period and contemporary pieces, signed jewels, independent watchmakers.
• Books & manuscripts: First editions, archives, maps, autographs.
• Wine & spirits: Vintage and rare bottles, casks, and collections.
• Select collectibles: Film posters, sports memorabilia, and other categories as curated by specialist teams.

What’s typically out of scope? Real estate, heavy machinery, most firearms, and categories that fall under other specialist industries. For certain niches (e.g., classic cars), Sotheby’s affiliated partners may handle valuations; for property better suited to regional markets, Sotheby’s can often suggest trusted alternatives.

The rule of thumb: If Sotheby’s actively sells a category at auction or private sale, they tend to support it with appraisal expertise. If they don’t handle a category in the marketplace, they may decline or refer.

Appraisal Types: Auction Estimates vs Formal Reports

Understanding appraisal purpose and value definitions is critical. Sotheby’s provides different valuation pathways depending on your needs.

• Auction estimates (preliminary or sale-specific):

  • What they are: An opinion of what an item might achieve at auction in current market conditions, typically expressed as a range.
  • Use cases: Deciding whether to consign, planning a sale strategy, initial triage of a collection.
  • Format: Often provided from images and information; final estimates are confirmed after in-person inspection before cataloging. These are not designed for insurance, tax, or legal purposes.

• USPAP-compliant formal appraisals:

  • What they are: Written appraisal reports prepared in accordance with the Uniform Standards of Professional Appraisal Practice (USPAP) and, where applicable, IRS requirements.
  • Use cases: Insurance scheduling or claims, estate tax, charitable contribution, equitable distribution (divorce or partnership dissolution), collateral lending, damage/loss, and financial reporting.
  • Value definitions (selected):
    • Fair Market Value (FMV): The price a willing buyer and willing seller would agree upon, neither under compulsion and both having reasonable knowledge of relevant facts. Common for estate tax and donations.
    • Retail Replacement Value (RRV): The cost to replace the item with a comparable one in the retail market; typically used for insurance.
    • Marketable Cash Value or Orderly Liquidation Value: Used in certain business or collateral contexts.
  • Features: Effective date of value, clearly defined intended use and users, methodology, comparables, limiting conditions, and signatures of qualified appraisers or specialists.

Choosing the right appraisal type hinges on intended use. Insurance carriers generally require RRV; tax authorities require FMV and adherence to specific regulations. Auction estimates, while useful, are not a substitute for formal reports in regulated contexts.

How the Sothebys Appraisal Process Works

Although projects vary by category and scope, most Sotheby’s appraisal engagements follow a structured path:

1. Initial inquiry and triage

• You share images, dimensions, inscriptions/signatures, medium, and any known history or prior valuations.
• Sotheby’s specialists assess category fit, potential value, and the appropriate appraisal type.

2. Scope and terms

• You receive a proposal outlining intended use, property list, timing, fees, and any site visit requirements. For large estates or multi-category collections, teams coordinate across departments.

3. On-site or in-office inspection

• For higher-value or complex works, an in-person inspection is standard to verify materials, condition, and authenticity indicators, and to identify restoration or issues invisible in photos.
• Measurements, condition notes, and high-resolution images are taken. For smaller items, you may be asked to bring them to a regional office.

4. Research and analysis

• Specialists review provenance, exhibition and publication history, artist market performance, and comparable sales across relevant markets and timeframes.
• For insurance valuations, they consider retail sources and replacement availability. For tax or gift/donation, they apply FMV and IRS conventions, including appropriate comparables and discounts if warranted.

5. Report preparation

• The written report specifies the value definition, effective date, methodology, assumptions, and limiting conditions. Each item receives an identification, description, and the concluded value.
• For charitable contributions at certain thresholds, appraiser qualifications and additional IRS-specific content are included.

6. Delivery and next steps

• You receive the report in digital and, if requested, hard-copy form. Sotheby’s can also provide valuations formatted for insurers or estate attorneys.
• If you’re considering selling, the appraisal can inform a sale strategy (auction or private sale), but the formal appraisal remains separate from any consignment agreement.

Typical turnaround ranges from a few days to several weeks depending on quantity, complexity, travel, and research depth. Significant estates or cross-border collections can take longer due to logistics and multidisciplinary review.

What drives accuracy and credibility:

• Category specialization: Department-specific expertise aligned to your property.
• Current market data: Global auction and private sale comparables, not outdated price guides.
• Clear intended use, value definition, and effective date: Ensures the report is fit for purpose and defensible.

Fees, Timing, and Confidentiality

• Fee structures

  • Formal appraisals are fee-based, often hourly or by project, and independent of value to avoid conflicts of interest.
  • Minimums may apply; travel and photography can be billed separately.
  • Preliminary auction estimates are commonly complimentary when aligned with potential consignment; formal written reports for tax, insurance, or legal use are paid services.

• Timelines

  • Single items: Often days to a couple of weeks.
  • Multi-property collections: Several weeks to months, especially when multiple departments are involved or when travel is necessary.

• Updates and revaluations

  • Insurance: Many collectors refresh RRV appraisals every 3–5 years or after major market shifts or restoration.
  • Estates and donations: Effective dates are fixed to a valuation date; if circumstances change, a new report with a new effective date is required.

• Confidentiality and independence

  • Appraisal contents, values, and client data are handled confidentially.
  • Where Sotheby’s also offers sale services, appraisal and consignment functions are kept procedurally distinct; formal appraisals carry their own scope, assumptions, and intended use.

• Limitations to remember

  • An appraisal is an opinion of value as of a specific date—not a guaranteed sale price.
  • Condition discoveries, provenance clarifications, or market shifts can alter value conclusions.

Practical Checklist: Get Appraisal-Ready

Use this concise checklist to streamline your Sotheby’s appraisal and improve accuracy:

• Identify intended use: Insurance, estate tax, donation, equitable distribution, collateral, or sale planning.
• List your property: Titles, artists/makers, mediums/materials, dimensions, edition numbers, serials, hallmarks.
• Gather documentation: Invoices, prior appraisals, certificates of authenticity, expert opinions, restoration records.
• Compile history: Provenance (ownership chain), exhibition history, literature references.
• Take clear photos: Front, back, details of signatures/labels/hallmarks, condition issues, frames/backs/versos.
• Measure precisely: Height, width, depth; note unframed vs framed dimensions and weight if relevant.
• Note condition: Cracks, repairs, overpainting, replaced parts, foxing, stains, wear; do not attempt new repairs before inspection.
• Confirm access: If onsite, ensure safe access to storage, lighting, ladders, and any required handling support.
• Clarify deadlines: Insurance renewals, tax filing dates, settlement timelines, or sale windows.
• Secure insurance and handling: For transit or in-office inspection, confirm packing, courier, and insurance arrangements.
• Set expectations: Fees, turnaround, deliverables, and who may rely on the report (intended users).
• Avoid last-minute cleaning: Do not polish silver, relacquer furniture, or clean paintings; improper cleaning can diminish value.

FAQ: Sothebys Art Appraisal Services

• Do I need a formal appraisal or is an auction estimate enough?

  • If you plan to insure, file taxes, donate, allocate assets, or borrow against an item, you need a formal USPAP-compliant appraisal with the correct value definition. If you simply want to explore selling, a preliminary auction estimate is usually sufficient to start.

• Can a Sotheby’s appraisal be used for IRS charitable contributions or estate tax?

  • Yes. Sotheby’s prepares IRS-compliant appraisals that state Fair Market Value and include qualified appraiser information and appropriate comparables. Your tax advisor can confirm the documentation required for your specific filing.

• Will Sotheby’s buy my item outright?

  • Sotheby’s primarily acts as an agent through auctions and private sales. In some cases, financial advances or guaranteed sale arrangements exist, but outright purchase is not the default model. A specialist can outline sale options after valuation.

• How accurate are online or photo-based valuations?

  • Specialists can provide preliminary views from images and documentation, but final values—especially for formal appraisals—depend on in-person inspection to verify condition, materials, and authenticity indicators.

• What if my items are below Sotheby’s threshold?

  • Sotheby’s may suggest regional auction houses or independent appraisers that fit your property and market level. Aligning the item with the right sales channel often yields the best net outcome.

By understanding how Sotheby’s structures appraisal services—what they appraise, which report you need, how values are determined, and how to prepare—you equip yourself to make informed, timely decisions. Whether you’re protecting a family heirloom, optimizing an estate plan, donating for impact, or charting a sale, a well-scoped Sotheby’s appraisal can turn a great object into a clear path forward.
