Expertise confirms the authenticity of a handwritten document and certifies that the document in question was indeed written by a particular author, artist, etc.

Autographes des Siècles, having specialized in manuscripts and autographs for many years, is at your complete disposal for any document you wish to submit for our evaluation. Naturally, in order to provide a 100% reliable opinion, we need to have the original document in our possession. A computer scan, while it may confirm or refute certain information, cannot in any way guarantee that the document you present to us is completely authentic.

We are therefore available to provide a free appraisal of your autographs at the bookstore, by appointment. We can also travel (free of charge) to your home for items of significant value. After careful examination of your autographs, you will be issued a certificate of authenticity , which serves as proof and certifies the document's complete authenticity indefinitely.

An appraisal allows you to establish a price scale for your documents. Indeed, a letter from Victor Hugo arranging a meeting with a stranger will not have the same value as a letter from the same Hugo to his lover, Juliette Drouet. A letter from Paul Verlaine to his wife, Mathilde, will be valued far more highly than a note from the poet requesting 5 francs from his publisher, Vanier.
