I have an old map. How much is it worth?
As a federally funded agency, the Library of Congress is unable to appraise or authenticate old maps and atlases, works of art, or other collectibles. Nevertheless, appraisal and authentication services may be available, possibly for a fee, from a commercial dealer in antiquarian maps and atlases, globes, or rare books.
A list of antique map dealers for your area can be found here.
