Five-phase antique and art appraisal framework basics
A defensible appraisal does not start with a price. It starts with a structured file: identify the object, inspect condition and authenticity risk, document provenance, analyze the right market, then report the conclusion with clear assumptions and records.
This framework works for fine art, prints, furniture, silver, ceramics, jewelry, watches, textiles, and mixed estate property. The details change by category, but the sequence prevents common mistakes such as using weak comps, overstating a signature, or ignoring restoration.

Check which phase your item is missing
Upload the full object, detail photos, measurements, signatures or labels, condition issues, and any documents. The free screener can flag whether the next step is identification, condition review, provenance, comps, or a signed report.
Start with a free screener. Use a signed report when you need insurance, estate, donation, resale, or formal documentation.
How We Research Valuation Data
Our appraisal guides are based on auction results, dealer pricing data, and professional appraiser insights. We may earn a commission when you use our free screener. Learn about our editorial standards.
Phase 1: Identification and classification
Define what the object is before choosing comps: artist or maker, title or subject, materials, dimensions, date, category, marks, edition, construction, and whether attribution is firm or conditional. Vague identification creates vague value.
Phase 2: Condition, authenticity, and integrity
Condition changes market tier. Record repairs, losses, fading, relining, dry mounting, replaced parts, overcleaning, cracks, dents, regilding, chips, or alterations. For authenticity risk, separate observed evidence from assumptions and recommend specialist testing only when it would materially affect value.
Phase 3: Provenance and documentary evidence
Provenance can increase confidence, salability, and sometimes value. Build a timeline from labels, invoices, auction stickers, estate inventories, exhibition history, ownership notes, and prior appraisals. If a document cannot be tied to the object, describe it as unverified rather than proof.
Phase 4: Market analysis and valuation method
Choose comps from the correct market: auction, retail replacement, dealer resale, private sale, or liquidation context. The value type matters. Fair market value, replacement value, and fast-sale guidance can point to different numbers for the same object.
Five-phase workfile evidence table
This table is not a price-comp table. It shows the minimum evidence a report should gather before the value conclusion is defensible.
| Photo | Phase | Date | Record | Value impact | What to verify | Source |
|---|---|---|---|---|---|---|
| Workfile | Identification and classification | Inspection date | Object ID sheet | Controls category, maker, medium, and comp universe. | Dimensions, materials, marks, title/subject, date, attribution level. | Object photos / appraiser notes |
| Workfile | Condition and authenticity | Inspection date | Condition file | Determines market tier and discount/premium adjustments. | Repairs, losses, restoration, alteration, signature/material consistency. | Inspection / specialist notes |
| Workfile | Provenance documentation | Record dates | Timeline | Can reduce risk and strengthen sale-channel confidence. | Labels, invoices, catalogs, ownership chain, prior images. | Owner records / archives |
| Workfile | Market analysis | Sale dates | Comparable sales | Anchors value to real market evidence. | Maker, medium, size, date, condition, subject, venue, fees. | Auction/dealer records |
| Workfile | Reporting and ethics | Effective date | Report/workfile | Preserves reasoning, scope, assumptions, and intended use. | Value type, intended users, limiting conditions, reconciliation. | Appraisal report |
| Workfile | Record management | Archive date | Retained file | Supports future review, insurance, estate, donation, or resale decisions. | Photos, comps, notes, documents, correspondence, updates. | Client/appraiser archive |
Takeaway: the framework is useful because every phase leaves evidence. If a phase is missing, the valuation should disclose the limitation or pause for more information.

A report should state intended use, intended users, effective date, value type, inspection limits, assumptions, comparable-sales reasoning, and final value conclusion. Keep the supporting workfile: photos, notes, documents, comp records, and correspondence.
Framework red flags
- Attribution claims without matching material evidence.
- Condition notes that omit repairs, losses, or replacements.
- Provenance documents that cannot be tied to the object.
- Comps from a different market level or value type.
- Reports that give a number without explaining assumptions.
- Using a fast-sale estimate as an insurance replacement value.

Wrap-up
The five-phase framework keeps appraisal work disciplined: identify the object, inspect condition, document provenance, analyze the market, and preserve the report workfile. It is especially useful when a value decision needs to be explained later.
