Advanced art and antique appraisal basics
Advanced appraisal work combines scholarship, material inspection, provenance research, market analysis, and reporting discipline. The goal is not just a number; it is a value conclusion that can be explained, reviewed, and relied on.
Use this framework for higher-risk objects, insurance files, estate work, donation decisions, disputed attribution, and collection planning. The more consequential the decision, the more important it is to document each assumption and source.

Six pillars of a defensible appraisal
- Identification: category, maker or artist, materials, dimensions, date, marks, and attribution level.
- Authentication: material consistency, stylistic fit, expert opinions, and proportionate testing.
- Condition: damage, restoration, repairs, completeness, stability, and inspection limits.
- Provenance: ownership chain, invoices, labels, prior sales, exhibitions, and title concerns.
- Market analysis: comparable sales, value type, market level, adjustments, and timing.
- Reporting: scope, intended use, intended users, assumptions, limiting conditions, and workfile support.
Advanced appraisal evidence table
This is not a price-comp table. Use it to confirm that the report has enough support before a value conclusion is relied on.
| Photo | Evidence | Date | Record | Value impact | What to verify | Source |
|---|---|---|---|---|---|---|
| Workfile | Identification and attribution | Inspection date | Object ID | Defines the market and comp set. | Maker, materials, dimensions, date, marks, attribution language. | Object photos / appraiser notes |
| Workfile | Authentication support | Research date | Testing or expert file | Can materially change value or saleability. | Material consistency, expert opinion, scientific limits, red flags. | Specialist/lab records |
| Workfile | Condition and conservation | Inspection date | Condition report | Controls discounts, risk, and market tier. | Damage, repairs, restoration, stability, reversibility. | Condition photos / conservator notes |
| Workfile | Provenance and title | Record dates | Document chain | Can raise confidence or reveal risk. | Labels, invoices, catalog records, ownership gaps, restrictions. | Owner/archive records |
| Workfile | Comparable sales | Sale dates | Comp set | Anchors value to market evidence. | Venue, realized price, fees, size, condition, quality, provenance. | Auction/dealer records |
| Workfile | Report and standards | Effective date | Appraisal report | Makes the conclusion usable for the intended decision. | Scope, value type, users, assumptions, limiting conditions, certification. | Report/workfile |
Takeaway: advanced appraisal is evidence management. The number is only as strong as the workfile behind it.

Find the weak evidence before relying on the value.
Upload photos, condition details, marks, provenance, and your intended use. The free screener can flag whether a signed report is worth ordering.
Use the free screenerMarket analysis and value definitions
Choose the value type before choosing comps. Fair market value, retail replacement value, auction estimate, and orderly liquidation value describe different markets and assumptions. Explain why each comp is relevant and how condition, provenance, quality, and venue change its weight.
Ethics, standards, and reporting
Advanced reports should state competency, independence, intended use, intended users, effective date, inspection limits, assumptions, and certification. Keep the workfile: photos, notes, documents, comparable sales, correspondence, and testing records.
