Authenticating an artwork is a specialist process that incorporates research, specialist knowledge, and, in some cases, scientific analysis.
At Mintus, our in-house team confirms the authenticity of the artworks we select in conjunction with independent third-party specialists.
Within the art market, three tools are used to verify whether an artwork is authentic: provenance, technical analysis, and connoisseurship.
In the case of many historical artists, the combination of these three approaches is used to compile a catalogue raisonné which is a comprehensive, illustrated, and annotated catalogue of all known artworks by an artist. This is sometimes divided into a particular time-period or medium (material) of an artist’s practice.
Some artists have associated Estates, Foundations or Authentication Boards that will use the listed tools to decide an artwork’s authenticity, and will provide accompanying documentation stating their decision. For example, the Henry Moore Foundation will authenticate any new works that don’t feature in Henry Moore’s current catalogue raisonné. Similarly, Banksy has an authentication board called Pest Control, which provide Certificates of Authenticity for his work.
At Mintus, we carefully consider the provenance and, where applicable, the catalogue raisonné of all our offerings, taking into account any additional documentation in order to confirm an artwork’s authenticity. Similarly, we contact relevant authentication boards when applicable. The experience of the in-house team, spanning gallery and auction house environments, ensures the best industry practices are followed during every step of the authentication process.If there is ever any doubt about the authenticity of the artwork, we don’t consider the work as a potential art investment offering.
