Dear Mr. Brewer,
Thank you for posting your request on History Hub!
The National Archives as the repository for the permanently valuable non-current records of the Federal Government has no authority to appraise historical documents that you may have. You may wish to contact the Appraiser Association of America that maintains a list of their members who are qualified to appraise historical documents.
We hope this is helpful. Best of luck with your research!
Thank you Charlie I will check them out. Aaron Brewer
