Read the name on the certificate, sticker or hologram. eBay advises buyers that COAs and LOAs are only as valuable as the reputation of whoever issued them [1].
eBay publishes a list of people and organizations whose COAs and LOAs are not allowed on its site [1]. The FBI's Operation Bullpen found that forgers commonly used COAs to make fake signatures look genuine [2].
Most large programs offer a lookup by certification or hologram number, including PSA [3], JSA [4], Upper Deck [5] and Fanatics [6]. Use the issuer's own website, not a link in a listing. Our directory links to each official lookup we found.
PSA warns that verifying a number "does not eliminate risk", because criminals sometimes copy real certification numbers from public sources [3]. Check the photo, signer and item type in the record against the item in front of you.
A missing record isn't automatically a bad sign. Upper Deck says items from before 2002 and many show-signed items aren't in its online database [7], and JSA has said new certifications can take weeks to post [8]. Contact the issuer directly.
