Certificates of Authenticity (COAs) are widely misunderstood in the collectibles market. Although they appear “official,” COAs are not regulated documents—and counterfeiters frequently forge or alter them to create the illusion of legitimacy. Fake COAs are now used across autographs, art prints, memorabilia, coins, props, and historical documents, making COA evaluation just as important as evaluating the item itself.
