The Last Price Is the Oldest Thing in the Record

A price records the last time somebody had to decide what an object was worth

A price is not a property of an object, it is the residue of a transaction. It records a moment when two parties had to convert an opinion into a number, and it stays valid as evidence of that moment and of nothing else. This is why the auction record is the part of a provenance that ages fastest and gets quoted longest.

What we did not expect, until we measured it across the whole archive, is how cleanly the age of that number sorts the collection in two. The dividing line is not medium, period, quality or fame. It is whether the object ended up in a museum.

Once it did, the price history stopped, usually permanently. Deaccessioning is rare and constrained, most of these objects arrived by gift or bequest with conditions attached, and nothing in the ordinary life of a public collection requires anybody to price a work again. The result is that the objects a reader is most likely to have heard of are the objects whose last recorded price is least informative.

The two halves of the archive are six decades apart

Eighty-eight of the 285 published records here carry a sale with a date attached, and splitting them by where the object is now produces two populations that barely overlap. The 64 records now in an institution have a last recorded price a median 26 years old, with a mean of 57. The 24 in private hands have a last price a median 8 years old, with a mean of 14.

The mean and the median diverge sharply on the institutional side and hardly at all on the private side, which tells you the shape of the distribution. Private objects cluster in the recent past because they keep trading. Institutional objects have a long tail running back into the eighteenth century, and that tail is made of exactly the works a museum would never sell.

Only one privately held object here has gone fifty years without a price, and it is the Beauvais Missal, which was broken up and dispersed as individual leaves: 122 of its 309 leaves have been located across more than a hundred collections, and there is no longer a single thing to sell. Our first pass produced a second apparent exception, and it was our own error. The Kandinsky in this archive shows a 1940 sale in Amsterdam and a 2023 sale to a private collector, and the 2023 entry carries no date in the field our count reads, so the object was binned as though it had not been priced in eighty-six years. We have corrected the figures above and are recording the mistake here rather than quietly fixing it, because it is the kind of error that makes a dataset look tidier than it is.

Two guilders and thirty cents, in 1881

The last price ever attached to Girl with a Pearl Earring was set in 1881 at the Braams sale at the Venduhuis der Notarissen on the Nobelstraat in The Hague. The buyer was Arnoldus Andries des Tombe, who got it for two guilders plus a thirty cent commission after Victor de Stuers, who had spotted it too, agreed not to bid against him. The Mauritshuis prints the total as f2,30.

Two things about that number are worth separating. The first is that it is not a single figure, and most accounts that quote one are conflating the hammer with the mark-up; both components are documented and this archive records them apart, as it does for every sale. The second is that we offer no modern equivalent, and we would ask any reader tempted to compute one to notice what the exercise assumes. The guilder amount is the fact. Any conversion is a derived estimate that depends on the date you choose and the index you pick, and the number people actually want, what the painting is worth today, is not a conversion of anything.

Des Tombe bequeathed the picture to the Mauritshuis in 1903. There has been no price since, and there will not be one.

Ninety francs and eleven centimes, for a Bruegel catalogued as German

The Harvesters was sold in Paris on 11 March 1816 for ninety francs and eleven centimes. The catalogue described it as the work of a master of the old German school, a landscape of the greatest detail showing the labours of the harvest, measuring 58 by 44 pouces and dated 1546.

Almost every element of that description is wrong. The painter was Netherlandish and was one of the most famous names of the preceding century. The panel is signed and dated 1565, not 1546. What survives of the description as accurate is the subject, which the cataloguer could see, and the size, which he could measure.

The two transactions that followed were private and carry no hammer price at all: Jacques Doucet sold it to Paul Jean Cels shortly before 1912, and Cels sold it to the Metropolitan Museum in 1919. The museum describes what it paid in 1919 as extraordinarily low and does not publish the figure. So the only public number this painting has ever carried is a sum in francs, set by somebody who had misidentified the school, the painter and the date.

A theft freezes the price instead of raising it

The Concert passed through at least six auctions between 1696 and 1892, and a price survives for only the last of them. On 5 December 1892 at the Hotel Drouot in Paris it went for 29,000 francs to the agent Fernand Robert, bidding for Isabella Stewart Gardner, who signalled from the room with a handkerchief. Agents for the Louvre and the National Gallery in London were underbidders and withdrew on realising they were bidding against each other.

It was stolen from the Isabella Stewart Gardner Museum on 18 March 1990 and has not been recovered. Legal title remains with the museum, and its location line in this archive reads unlocated.

The painting is routinely described as the most valuable stolen work in the world, with figures in the hundreds of millions attached. Those numbers are not prices. Nobody has been asked to pay one, no transaction has tested one, and the object cannot be delivered. The last real number attached to The Concert is 29,000 francs from 1892, and a theft did not make it larger, it made it permanent.

One price in three hundred years, and objects that can never have another

The Messiah Stradivari carries exactly one documented market transaction in its entire history. In 1890 the heirs of Delphin Alard sold it through W. E. Hill and Sons to Robert Crawford of Edinburgh for 2,600 pounds, reported at the time as the largest sum ever paid for a single violin. It has not been sold since 1904 and has not been a market object at all since it reached the Ashmolean.

Canova's Napoleon as Mars the Peacemaker sits at the far end of the same logic: it has never been at auction and now cannot be. It passed from the sculptor to the French imperial state, to the restored French regime, to the British government by purchase in 1816, to the Duke of Wellington as a gift from the Prince Regent, and to the nation by statute in 1947. The one recorded number in that sequence is a government purchase, not a hammer, and even the sterling figure usually quoted is a period conversion that should be read as an order of magnitude rather than a price.

Between them these two mark the boundary of what the market can see. An object that trades produces evidence. An object that moves by gift, bequest, statute and state transfer produces paperwork, and the paperwork does not contain a number.

How to read a price with a date on it

Read the date before the number, every time. A hammer price is evidence about the day it was struck, and on this archive's own figures the median institutional price is 26 years old and the mean is 57. Quoting a figure from 1881 or 1816 without its date is not shorthand, it is a different claim from the one the record supports.

Ask what the sale actually tested. The Harvesters at ninety francs tested a misattributed old German landscape, not a Bruegel. Girl with a Pearl Earring at f2,30 tested an unattributed picture in poor condition at a notary's sale. In both cases the number is real and the thing it measured is not the thing we now think we are pricing.

Then treat the absence of a recent price as information rather than a hole. When an object stops being priced it is usually because it has entered a collection that will not sell it, and that is a substantive fact about its status. The valuations that circulate for famous museum pieces and famous stolen ones are estimates produced for insurance, for journalism or for nothing in particular, and they are not what this archive means by a price.
