When artists sell their work, they must provide a Certificate of Authenticityin order to be more professional and give all the guarantees to the buyer. A Certificate of Authenticity is essential for the attribution of a work.
Without a Certificate of Authenticity, it's impossible to determine the artwork's origin or to attribute it to an artist. The only value it has will depend on its size, the technique, the materials, and the subject represented.
A Certificate of Authenticity is the key to the successful sale of your works. You must provide a Certificate of Authenticity to the buyer (even if he or she does not ask for one) along with the invoice.
Without a Certificate of Authenticity, most doors will remain closed; no estimate, no transaction. A Certificate of Authenticity is mandatory to establish that a work of art is authentic and has been created by the Artist.
No mention in a raisonné catalog about the financial value of the artwork. Without a Certificate of Authenticity, it's impossible to evaluate the artwork, its only value depends on its size, its technique, the materials used and the subject represented.

THE CERTIFICATION OF THE VALUE OF ART. EXPERTS AND EXPERTISE
Raymonde Moulin | Alain Quemin
Annals Year 1993 48-6 pp. 1421-1445
Part of a thematic issue: Worlds of art
Today we are witnessing the proliferation of expertise and recourse to experts has become a fashion phenomenon which does not spare artistic policy. The competence of the professional culminates in expertise and if all experts are not professionals in the sense that the word has in Anglo-Saxon sociology, they generally aspire to become so. Political and administrative officials, for their part, have become accustomed to appealing to the objectification capacity of experts. The commission of experts thus appears as the updated version of the very general and very old consultation process of the republican administration, both protection and alibi.

To minimize the risk of choice, political leaders in the artistic field as in other fields, surround themselves with experts by handing over the competence of specialists. Expertise thus becomes one of the major mechanisms for constructing the value of art. It is not forbidden to question, finally on the certification of experts authenticating the value of art and on the criteria to which they refer to build the certification of the value of art and the reputation of artists. Artistic markets, and especially the contemporary art market, are contexts in which uncertainty dominates, uncertainty about the value of goods; on the value of the skills required to achieve professional success, whether it is experts or artists. The term expertise has multiple meanings of which we are far from having exhausted the list. Limiting our analysis to the definition of expertise in French usage, we noted the delayed effect of professionalization on activities related to art, on the one hand; the increased role of expertise in the dual form of attribution and validation in building the value of art, on the other hand. The certification of value conditions the price even if, because values constitute an articulation of the artistic field and the market, the price can be one of the criteria for the certification of value.
