The price is the value of a work obtained at auction. Of course, the price of an artist can fluctuate depending on the economy, the career of the artist. To be credible, the listing must be sustainable over several years. Every painting or statue is different.

Finding an artist's rating is inquiring about the value of a painting, a sculpture or any work of an artist in order to sell it. Indeed, before selling your work of art, it is necessary to know the quotation of the artist. This rating determines the price to be set at the time of sale.

But there are many sources of information, and it is not always easy for a neophyte to navigate. Unfortunately, an average artist rating will not tell you the value of your painting or sculpture.

The price is the value of a work obtained at auction. Of course, the price of an artist can fluctuate depending on the economy and the artist's career. To be credible, the listing must be sustainable over several years.

Every painting or statue is different. Many criteria must be taken into account: the period, the rarity of works on the market, the quality of the cast for a bronze, the subjects treated in painting in line with what is most sought after on the art market for the artist concerned.

Some artists, although listed at international fairs, are not yet on the secondary market. We must therefore differentiate the official rating of an artist at auction, such as a justice of the peace and the rating of an artist in a very confidential setting of galleries or fairs. Some works can be sold at exorbitant prices in the framework of international fairs and do not convince any amateur in auction.

To determine the value of a painting or a sculpture is to communicate an estimate range between a low estimate and a high estimate. Very often, the low estimate corresponds at auction to the reserve price, below which the work will not be sold. This allows you to determine an average value of your property. The price of the artist for sale is based on the auction or hammer price, not including the costs of the sale in addition to the auctions which are between 20 and 25%.


Most of you have legitimate questions, seeing very high artist ratings advertised for some painters and paintings advertised at much lower amounts.

Art cannot be compared to the stock market and there is no monthly settlement of securities. We also do not set the rating or the price of a painting like that of a precious stone which can be scientifically evaluated by its weight in carats, its purity, the calibration of its color as well as the quality of its size. .

To talk about painting by a living artist, his career spans years and within a relatively hermetic world, made up on one side by professionals, whether art critics , international dealers or auctionners, and on the other by true amateur collectors, whose taste and knowledge presided over their choices.

Often regarded as a benchmark in terms of price, the interpretation of a public sale quotation should be approached with great caution.

First, because a price obtained at auction for a specific work may never be repeated, including for the same painting and at the same place if the sale takes place under other circumstances and on another day.

Imagine two similar paintings going up for auction at the same time, one at the Drouot hotel in Paris, in a cataloged sale that attracted many enthusiasts from all over the world, and the other in a regular weekly sale in a small town in Upper Loire, the price difference could be from one to one hundred for a contemporary work.

Let's not compare with a painting from an old master that will always be backed up for sale by the professionals who are always mysteriously informed when an interesting painting surfaces somewhere.

Between the painting sold in Paris and that of the Haute Loire, what is the good rating that should serve as a reference? Probably neither if the first got a particularly high price while the other sold for an unusually low sum.

However, the two results will be published in Artprice (a website that seems to meet a lot on the coast) and a potential buyer will have a hard time navigating it if he wants to form an opinion.

We cannot stress enough the random nature of an auction with conditions that we will never find identically. The public will be different, the economic context too, other paintings in the same sale may also be in competition and disperse the bidders.

To obtain a good price at auction, it also takes several amateurs to compete for the object, otherwise the auctioneer is forced to go up 'in the void' to the reserve price against the only bidder present in the room. It has often happened to me to obtain bids much higher than the usual price of an artist because I was present every month in different auction rooms and it happened that a painting obtaining a record auction was withdrawn. previously several other public auctions without having reached its reserve price.

Keep in mind that there are no strict rules in the art and you have to work on a case by case basis. It is a little simplistic to think that it is enough to bring an AKOUN guide to improvise a picture dealer.

In this regard, the question is often asked about the difference between the AKOUN rating displayed by EBAY members and the price they ask for their table. It is therefore necessary here to explain precisely how the AKOUN rating works and how it is established.

This so-called 'average' dimension, which is already ready to smile given that each painting that is sold is different from its neighbor, is calculated on the average basis of a painting measuring 65 X 50 cm, corresponding to a 15 Landscape. So, if only paintings measuring 22 X 27 cm are up for auction, or 3 F, AKOUN will multiply the price by 5 to obtain the average odds of a 15 P. It suffices that several 3 F paintings measuring 22 X 27 cm sold for 500 euros to find an AKOUN rating of 2,500 euros corresponding to a 15 P. It is quite possible that these paintings having reached 500 euros were at auction with a reserve of 250 euros and that a competition between several bidders brought them to double that price. For this reason, you can find on Ebay tables with a reserve price of 250 euros or for immediate purchase while their AKOUN rating is 2,500 euros. There is nothing wrong with this and there is no point in sending derogatory emails about it.

In addition, to establish its rating, AKOUN's main source is the results that merchants and artists send it at the end of each year before December 15. At least three results are required for an average rating to be established. So if you have auctioned 30 or 40 paintings of an artist in a year, it will suffice to send the most significant results to AKOUN to obtain a rating, let's say ... optimized. Far be it from me to criticize the AKOUN guide which is extremely practical in a reduced format, but it should be borne in mind that a public sale result is only the witness of a past event which is not necessarily reproducible.

In short and if you read everything correctly ... The RATING of an ARTIST really only exists in relation to the demand for the works of this artist ... If the artist is not really known ... It will be the PRICE at which he sells his own paintings that will determine the cost ... But only in front of his potential buyers ... For others, his rating will mean nothing ... Because the COAST is not at all a science exact, and want more than one guess ...

Clearly, it is the buyer who makes the estimate of the artist ... If the buyer buys his painting at 500 euros, his quotation is 500 euros.

The certificate of authenticity

When selling one of your works, in order to be more professional and offer all the guarantees to your buyer, the artist must provide a certificate of authenticity.

A certificate of authenticity is a document necessary for the attribution of a work. Your customers will be very sensitive to this particular attention that values you as an artist and guarantees the authenticity of your works. Without a certificate of authenticity, it is impossible to evaluate the work according to its provenance or to relate it to an artist. Its only value depends on its size, technique, materials used and the subject represented.
