Antiques and art appraisal field manual basics
A field manual turns appraisal work into a repeatable checklist. Use it to define the assignment, document the object, separate provenance from attribution, test materials and condition, choose comparables, and write a report that can be reviewed later.
Free first read
Check whether your appraisal file is complete
Upload object photos, marks, condition issues, provenance documents, dimensions, and intended use. The free screener can flag missing evidence before a signed report.
Start with a free screener. Use a signed report when you need insurance, estate, donation, resale, or formal documentation.
1. Use the four field pillars
Provenance, rarity, condition, and demand drive most antique and art value conclusions. Provenance supports ownership and authenticity. Rarity only matters inside a desirable market. Condition controls risk and buyer confidence. Demand is confirmed through recent, relevant sales rather than anecdotes.
2. Build the object biography
Document maker marks, retailer labels, inscriptions, exhibition tags, restoration invoices, old photographs, bills of sale, and family records. Separate documented provenance from reported history, and state gaps clearly.
3. Combine connoisseurship with targeted testing
Start with visual inspection: wood species, joinery, tool marks, metal seams, ceramics footrings, glaze wear, canvas supports, paper watermarks, and signature behavior. Add testing only when it answers a value-bearing question.
Field manual evidence table
This table is not a price-comp table. Use it to verify that the appraisal file supports the final value conclusion.
| Photo | Evidence | Date | Record | Value impact | What to retain | Source |
|---|---|---|---|---|---|---|
| Scope | Assignment and value type | Effective date | Scope file | Sets market level and research depth. | Intended use, users, value definition, inspection limits, assumptions, and report type. | Client/report file |
| Object | Identification | Inspection date | Object record | Controls attribution and comparable selection. | Maker, period, materials, dimensions, marks, labels, inscriptions, and images. | Object photos / notes |
| Docs | Provenance | Record dates | Ownership timeline | Can increase confidence or reveal risk. | Invoices, exhibition history, labels, estate records, export notes, and unresolved gaps. | Owner/archive records |
| Condition | Condition and restoration | Inspection date | Condition file | Controls originality, risk, and market tier. | Damage, repairs, replaced parts, overcleaning, stability, and conservation documentation. | Detail photos / conservator notes |
| Market | Comparable sales | Sale dates | Comp set | Anchors the value range. | Venue, lot, price basis, buyer premium, condition, size, attribution, and adjustments. | Auction/dealer records |
| Report | Reconciliation | Report date | Final report | Makes the conclusion reviewable. | Accepted and rejected comps, assumptions, limitations, value reasoning, and certification. | Signed report / workfile |
Takeaway: a field manual is useful only when each conclusion can be traced to retained evidence.
Need the evidence reviewed?
Upload photos and documents before relying on a value.
The free screener can check whether your appraisal file has enough identification, condition, provenance, and market evidence.
Use the free screener4. Build comparable sales deliberately
Use comparables that match maker or attribution, period, medium, size, subject, condition, provenance, sale venue, date, and market geography. Normalize buyer premium, currency, and timing, and explain why outliers were accepted or rejected.
5. Treat restoration as market evidence
Conservation can stabilize and preserve value, but over-restoration, refinishing, overcleaning, replacement parts, and concealed repairs often reduce market confidence. Document what changed, who performed the work, and whether treatment is stable and reversible.
6. Write notes that withstand review
A report should state object identification, condition, provenance, methodology, comparables, assumptions, limiting conditions, value conclusion, effective date, and image support. Preserve the workfile so the conclusion can be updated when new evidence appears.
FAQ
What should an appraisal field manual include?
It should include intake scope, object identification, provenance, condition, materials analysis, comparable market evidence, value definition, assumptions, limitations, and report-writing notes.
When should scientific testing be used?
Use testing when it answers a specific value-bearing question that visual review cannot settle, such as material age, pigment consistency, metal composition, hidden structure, or ceramic firing date.
How should restoration be handled in an appraisal?
Describe the restoration specifically, note whether it is stable and reversible, and explain how it affects marketability, originality, risk, and comparable selection.
