What is autograph authentication?

Autograph authentication is the process of verifying the genuineness of a signature or autograph, typically on memorabilia, documents, or collectibles. Experts use a combination of forensic analysis, signature comparison, and historical research to determine if an autograph is authentic or forged. This process helps collectors, buyers, and sellers ensure the legitimacy and value of signed items. Authentication often results in a certificate or letter of authenticity from a recognized authority in the field.
