Frequently asked questions
How much does the valuation cost?
Nothing. The service is entirely free, offered with a view to a potential purchase proposal on our part—which you are free to refuse.
What if you offer to buy the book?
You are free to accept, refuse, or seek other opinions. We strongly encourage you to compare with an auctioneer or an expert accredited by CNE/SLAM before making any decision, especially for the most valuable pieces.
Is my book in poor condition, does it still have any value?
Possibly. Condition is a major but not exclusive criterion. For certain rare pieces, even incomplete or damaged, the value may remain significant. Send us your photos, and we will give you an honest assessment (including if the book has no significant market value).
