The first value question is whether the object can be lawfully, ethically, and confidently transferred.
Value sequence
- Confirm lawful title and transferability.
- Define the object narrowly and state uncertainty.
- Map restoration, composites, losses, and active deterioration.
- Assess provenance quality and publication history.
- Compare matched completed sales, not dramatic asking prices.
- Adjust for venue, premium, taxes, shipping, insurance, and return risk.
Why documentation changes value
Two visually similar objects may have radically different markets when one has an old, named collection history, export documentation, publication, and conservation record while the other has only a recent online certificate.
Value categories
| Value | Purpose |
|---|---|
| Fair-market value | Likely price between informed willing parties under ordinary conditions. |
| Auction estimate | A marketing range for a specific venue and sale, not a guarantee. |
| Insurance replacement | Cost to replace with a comparable documented object, often higher than auction value. |
| Liquidation | Rapid-sale value with limited marketing and greater discount. |
Provenance is not optional: Ask for the ownership chain, invoices, export basis, import history, prior publications, restoration record, and exact seller representations. “Old collection,” “estate find,” and “from Europe” are not independently testable provenance.
Compare documented collector listings
Use listings to study measurements, material, form, restoration, documentation, seller language, and market supply. Do not treat an asking price or a certificate alone as proof.
