In short: A work of art does not have one value but several, depending on the purpose. Insurance value answers the question of what replacement would cost. Market value answers the question of what a sale would achieve under normal conditions. Using the wrong type of value leaves you underinsured, paying too much premium or dividing an estate on the wrong basis.
Why there are several values
The art market has two levels: the retail market of galleries and dealers, and the secondary market of auctions and private sales. Whoever has to replace a work usually buys at retail and pays more. Whoever sells achieves the secondary-market price less costs. This is why insurance value is usually higher than market value, and why every valuation report must state which type of value it determines.
The main types of value at a glance
| Type of value | Question | Typical occasion |
|---|---|---|
| Insurance value (replacement value) | What would it cost to replace a comparable work in the trade? | Insurance policy, loans to exhibitions, transport |
| Market value (fair market value) | What price would a willing buyer and a willing seller agree? | Estate division, divorce, tax, gifts |
| Auction estimate | Within which range is the work likely to sell at auction? | Consignment to an auction house |
| Liquidation value | What would a sale under time pressure achieve? | Forced sale, urgent need for liquidity |
| Lending value | What cautious value will a bank accept as collateral? | Art-backed loan, Lombard loan |
Insurance value: too low costs more than too high
If a collection is underinsured, the insurer may reduce its payment in the event of a claim, even for partial damage. If it is overinsured, you pay too much premium for years without receiving more than the actual loss. Many policies are based on invoices that are ten or twenty years old. For sought-after artists the replacement value has risen markedly since then; for others it has fallen. Regular reviews, more often in volatile markets, are therefore sensible.
Market value: the basis for estates, divorce and tax
When assets are divided or assessed, market value is usually the standard: in estate divisions, under Swiss marital property law (Art. 211 Civil Code) and towards the tax authorities. Using insurance value here overstates the collection: compensation payments turn out too high, and tax may be assessed too high. Whether and how a collection is captured for wealth or inheritance tax differs by canton and should be clarified with a tax adviser.

Lending value: what the bank will count
Banks and specialist art lenders work from a cautious market value and lend a fraction of it. An insurance value is not suitable for this. More in Art lending: liquidity without selling the collection.
How to recognise a useful valuation report
- The type of value and the valuation date are stated explicitly.
- The purpose and the addressee are recorded, such as insurer, tax authority or heirs.
- Comparable sales and assumptions are documented transparently.
- Each work is clearly identified: photos, dimensions, signature, provenance.
- The valuer is independent: no value-based fee, no sales commission.
One report, several values
You often need more than one type of value, for example a current insurance value for the policy and a market value for estate planning. Both can be prepared in a single assignment, which saves effort and cost. How fees are made up is explained in What does an art appraisal cost?
How I work
In a free initial conversation we clarify what you need the value for and which type of value the relevant party requires. You then receive a binding framework for fee and timing. I work independently, with fees based on time spent and no commission from the other side.

Frequently asked questions
Why is insurance value higher than sale proceeds?
Insurance value reflects the trade price at which a comparable work would have to be replaced. A sale achieves the secondary-market price, less costs.
Can I use the insurance valuation for an estate division?
Better not. For estate division, divorce and tax, market value is the standard. An insurance valuation would usually overstate the collection.
How often should the insurance value be reviewed?
Regularly, and at the latest after major market movements, new acquisitions or a move. Many collectors have their holdings updated every few years.
Is there an official value for a work of art?
No. Every value is a reasoned assessment for a specific purpose and date. That is why every report must disclose the type of value, the valuation date and its assumptions.
