- The Certificate of Authenticity (COA) is the only official document verifying that the painting is original and was created entirely by Kostas Loustas.
- A certified work of art potentially sells at a higher price than a work without documentation.
- It is an essential document for insuring the artwork against theft or damage, as well as for lending purposes (exhibitions, etc.).
- Certification by the legal heir/representative prevents the circulation of fake works in the market, thus protecting the artist’s reputation and the owner’s investment.
- The certificate establishes the first official reference point in the chain of ownership. This history is vital for a potential future resale and for the historical record of the artwork.
- It ensures that the work can be easily traced and verified, even after multiple changes of ownership, as the certificate always accompanies the work.
- The issuance of the certificate contributes to the recording of Kostas Loustas’s work and the broader effort of the Loustas Fine Art Estate to enrich its archive.
- It is issued in both Greek and English.
