Antique and art appraisal workflow basics
A reliable antique or art appraisal follows a simple order: gather, inspect, compare, decide. Skipping ahead to a price before the object is identified, measured, photographed, and checked for condition usually leads to weak comps and unreliable value ranges.
Use this workflow for paintings, prints, furniture, silver, ceramics, jewelry, watches, textiles, and mixed estate items. The category changes the inspection details, but the appraisal logic stays the same: build an evidence file, test the object, choose relevant market data, and state the value conclusion with its assumptions.

Step 1: Gather object facts and documents
Start with the basics: category, maker or artist, title or subject, materials, dimensions, marks, inscriptions, labels, provenance, ownership history, and intended use. Photograph the whole object, all sides, signatures, labels, damage, repairs, and any paperwork.
Step 2: Inspect materials, construction, and condition
Inspection turns a broad identification into a specific market object. For paintings, look at support, surface, signature, frame, repairs, and UV clues. For furniture, check woods, joinery, hardware, surface, and replaced parts. For silver and jewelry, document marks, metal content, fabrication, stones, wear, and repairs.
Condition is not a side note. Cracks, relining, overcleaning, fading, chips, restoration, missing parts, dry mounting, and replaced hardware all change which comps are useful.
Step 3: Compare against the right market evidence
Comparable sales should match the maker, object type, date, medium, size, condition, quality, subject, provenance, and market level as closely as possible. Retail asking prices, auction estimates, hammer prices, and private-sale reports are not interchangeable. Record the sale venue, date, lot, price, fees if relevant, and why the comp is similar or different.
Workflow evidence table
This table is a workfile guide rather than a price-comp table. It shows what evidence should exist before an appraisal conclusion is strong enough to rely on.
| Photo | Step | Date | Record | Value impact | What to verify | Source |
|---|---|---|---|---|---|---|
| Workfile | Gather full object photos and measurements | Inspection date | Photo set | Prevents wrong-size and wrong-category comps. | Front, back, sides, details, scale, frame/base/underside. | Owner photos / appraiser notes |
| Workfile | Record marks, labels, signatures, and paperwork | Document date | Provenance file | Can support attribution, ownership history, or sale-channel choice. | Exact transcription, location, document match, external records. | Receipts, labels, catalogs |
| Workfile | Inspect materials and construction | Inspection date | Condition notes | Condition controls market tier and comp selection. | Repairs, replacements, fading, cracks, mounting, restoration. | Appraiser inspection |
| Workfile | Select comparable sales | Sale dates | Comp set | Anchors value to the right market level. | Maker, medium, size, quality, condition, provenance, sale venue. | Auction/dealer records |
| Workfile | Adjust and reconcile | Effective date | Value conclusion | Turns evidence into a supported range or point value. | Adjustments, weighting, assumptions, intended use, currency. | Appraisal workfile |
| Workfile | Choose next action | Decision date | Sale, insurance, estate, or conservation plan | Aligns value type with the real decision. | Fair market vs replacement value, timeline, risk, fees, shipping. | Client objective |
Takeaway: a price is defensible only when the file shows how the object was identified, inspected, compared, and reconciled.

The free screener can flag missing photos, weak comps, condition questions, and whether a signed report is worth ordering.
Use the free screenerStep 4: Decide the value type and next action
The same object can require different values depending on use. Insurance often asks for replacement value. Estate, donation, and equitable distribution work often need fair market value. A quick resale decision may use a practical auction or private-sale range. State the value type before reconciling the comps.
Workflow red flags
- Pricing from one unsourced online listing.
- Using retail asking prices as auction realized prices.
- Ignoring condition differences between the item and comps.
- Assuming a signature is authentic without material support.
- Choosing comps before confirming size, medium, and date.
- Using an insurance value for a fast-sale decision.

Wrap-up
A four-step appraisal workflow keeps the value conclusion tied to evidence. Gather the file, inspect the object, compare it to the right market, then decide the value type and next action. The better the workfile, the less guesswork in the appraisal.
