One of the most deeply rooted myths of the art and antiques market is the belief that rarity automatically means high value. Owners often say: “It is the only example,” “There is no other,” “It is an absolute unique piece” — and expect the market to respond with enthusiasm. Meanwhile, the market reacts coolly. Because rarity alone is not yet value. It is merely a characteristic. Value is determined by demand. And demand follows a logic that can be ruthless to unique objects.
From forty years of observing the market, one conclusion is clear: rarity without demand is a curiosity, not capital.
Rarity is a fact, demand is a mechanism
Rarity means that an object appears rarely or has no comparisons at all. Demand means that there is a real group of buyers willing to pay a certain price for a given type of object. These two concepts are often confused, although they describe completely different phenomena.
The art and antiques market is not a museum of curiosities. It is a market of comparisons, references, and repeated purchasing decisions. Paradoxically, a serial work—if recognizable, documented, and repeatedly traded—can be a safer investment than a unique object that no one has ever bought before.
Why the market favors series
Serial works—prints, editioned sculptures, recurring painterly motifs—have one enormous advantage: they generate data. There are previous sales, price ranges, and patterns of increases and declines. For the market, this information is invaluable.
Collectors, investors, and institutions do not buy only an object—they also buy knowledge about how that object has behaved on the market. A series provides:
the ability to compare quality between examples,
price predictability,
lower risk of overpaying,
greater liquidity upon resale.
That is why a serial work by a recognized artist, even if not outstanding, can achieve stable and high prices, while a formally more interesting unique object remains difficult to sell.
The unique object as a problem, not an advantage
Uniqueness means lack of reference. And lack of reference means risk. The market then asks questions that often have no good answers: Will anyone else want to buy this? How do you price something that has never been sold before? Does the object fit into any collecting category? Can it be sold outside the local market?
If these questions remain unanswered, rarity ceases to be an advantage. It becomes a burden. A unique object requires narrative, while the market prefers data.
Demand is selective, not fair
A common mistake made by owners is the belief that the market “should appreciate” rarity. But the market does not operate on moral obligation. It operates on purchasing decisions.
If collectors are not building collections around a given type of object, if institutions show no interest, if dealers see no possibility of resale—demand does not arise, regardless of uniqueness.
Market history contains many examples of one-of-a-kind objects that failed to find buyers for years, and serial works that circulated between collections at ever higher prices. This is not a paradox. It is a mechanism.
Relative rarity and absolute rarity
It is worth distinguishing two concepts that are often conflated: absolute rarity—a single object with no comparisons; relative rarity—an object that appears rarely but is known to the market.
The market responds far better to relative rarity. A work that appears once every few years but is recognizable, documented, and desired can reach very high prices. An absolutely unique object, lacking context, is treated cautiously—or avoided altogether.
Collecting context matters more than uniqueness
An object gains value when it fits into an existing collecting model. Collectors build collections around themes, artists, techniques, and periods.
A serial work fits such a model more easily. A unique object often requires creating a separate category—something few buyers are willing to do.
That is why the market often rewards “understood” objects rather than “exceptional” ones. Exceptional uniqueness without demand remains a descriptive feature, not a price-forming factor.
Price is not a reward for rarity
The most important lesson to remember is this: the market does not reward uniqueness.
The market pays for what is desired, recognizable, comparable, and resalable. A unique object can be worth a great deal—but only when real demand exists to absorb that rarity.
Without demand, rarity does not raise price. Sometimes it even lowers it.
Conclusion
Rarity and demand are two different poles of valuation. Rarity is a fact; demand is a process.
A serial work may be more expensive than a unique one because the market knows how to handle it. A unique object requires faith. And the art market, contrary to appearances, does not operate on faith—it operates on decision.
Therefore, in professional valuation the question is not: “Is this rare?” but rather: “Who would buy this—and why?”
