certificate of authenticity
Proof of legitimacy
A certificate of authenticity is an official document attesting that an item is genuine.
Art dealers, auction houses, and memorabilia sellers issue them to verify provenance and justify value: The painting came with a certificate of authenticity from the gallery.
Their reliability varies—some are rigorous, others barely worth the paper they're printed on.
Often abbreviated COA.
