Buying art can feel like a matter of taste, but taste does not protect you from overpaying for a misattributed work, a clever reproduction, or a piece with hidden condition problems. An appraisal is what separates buying with evidence from buying on faith.
Whether you are purchasing a single painting for your home, a print for a collection, or a group of works for resale, a professional opinion of value and authenticity should come before the money changes hands. This article explains what an appraisal actually tells you, the mistakes buyers make when they skip it, and why the person writing the report matters as much as the report itself.
A Price Tag Is Not an Appraisal
The number on a gallery tag, an auction estimate, or a seller’s asking price is a marketing figure, not a professional opinion of value. A price tag reflects what someone hopes to receive. An appraisal reflects what the evidence supports.
A credible appraisal is based on research: the artist’s identity and attribution, the medium, dimensions, condition, edition information, signatures, provenance, exhibition history, and sales of comparable works. It explains the market that was considered and why the conclusion is reasonable. A price tag does none of that.
The gap between the two can be enormous. A work sold as an “original” may be a later reproduction, a posthumous print, or a piece with uncertain authorship. Without an appraisal, the buyer is the one absorbing that risk.
The Most Common Buying Mistakes
Most overpayments do not come from a lack of interest in art. They come from one of a few predictable mistakes.
The first is trusting the seller’s story. A signature, a certificate, or a family anecdote can all be genuine and still not establish value. Signatures can be copied or added later. Certificates are only as reliable as the authority behind them. A professional appraiser checks the claim rather than repeating it.
The second is assuming that a famous name means a valuable piece. Every major artist produced work of widely varying value. An early print is not the same as a later edition. A small sketch is not a major canvas. A work from a weak period or an unpopular subject can trail the artist’s headline auction results by a wide margin. Value is specific to the object, not the name.
The third is ignoring condition. Tears, flaking paint, fading, staining, amateur repair, and altered dimensions can all reduce value sharply, even when a work is authentic. Many buyers never look closely enough to notice these issues until they try to resell or insure the piece.
Use an Appraiser Who Belongs to a Recognized Organization
Not everyone who calls themselves an appraiser is qualified to give you a defensible opinion of value. One of the simplest ways to protect yourself is to work with an appraiser who belongs to a recognized professional organization.
Membership in a group such as the International Society of Appraisers (ISA), the American Society of Appraisers (ASA), or the International Fine Art Appraisers (IFAA) signals that the appraiser follows established standards of practice, ethics, and continuing education. These organizations hold members to written codes of conduct and require that appraisals be performed independently and objectively.
This matters for two reasons. First, an independent appraiser has no incentive to inflate a value to close a sale or to deflate it to buy low. Second, a report written to recognized standards will hold up when it is later reviewed by an insurer, an attorney, an accountant, or an executor. An opinion you cannot rely on later is not worth much at the time of purchase.
Ask the appraiser about their credentials, their area of specialty, and whether their fee is independent of the value they conclude. A fee tied to the appraised value creates an avoidable conflict when the assignment calls for impartiality.
What a Pre-Purchase Appraisal Should Cover
A useful pre-purchase appraisal addresses more than a single number. It should identify the work as thoroughly as possible, note any questions about attribution or condition, and place the piece in the correct market.
Expect the report to include the artist or attribution, the title if known, the medium, dimensions, signature and markings, condition observations, and any relevant provenance. It should explain which market was considered, whether that market is retail, auction, or a specialized collector category, and how comparable sales were selected.
When attribution is uncertain, the correct answer is often further research rather than a confident but unsupported claim. A good appraiser will be direct about what is known and what requires more investigation. That honesty is far more useful to a buyer than a number built on assumptions.
How an Appraisal Protects You After the Purchase
The value of an appraisal does not end at the point of sale. It becomes the foundation for everything you do with the work afterward.
If you insure the piece, the insurer will want a documented value. If you later consign or resell it, you will need a realistic basis for setting expectations. If the work becomes part of an estate or a charitable donation, a formal appraisal is often required. In each case, the report you obtained at purchase protects you by establishing a documented, defensible starting point.
A work bought without an appraisal leaves you guessing on all of these questions. You may carry insufficient insurance, overstate the value to a buyer, or discover at resale that the “bargain” was not one. The cost of the appraisal is almost always small compared to the cost of the mistake it prevents.
Buy With Evidence, Not Hope
Art is an acquisition you should be able to stand behind long after the purchase. An appraisal from a qualified, independent professional is the way to make sure you can.
If you are considering a purchase, bring the work or its documentation to a credentialed appraiser before you commit.
