Sorry to say you are mistaken; a "CERTIFICATE" is a certified copy.

"In a more particular sense, the written declaration, under the hand or seal or both, of some public officer, to be used as evidence in a court, or to substantiate a fact. A certificate of this kind may be considered as given under the oath of office."
