What does authenticity mean?
Authenticity is the quality of being genuine, original, and true — whether applied to objects, documents, works of art, or people. When we speak of the authenticity of a painting or a signature, we mean that it really is what it claims to be, not a forgery or reproduction; when we praise the authenticity of a person, we mean they are sincere and faithful to their own character rather than pretending to be someone else. The word derives from Greek roots via Latin and English 'authentic', and it has become one of the most valued qualities in modern culture: museums employ specialists to establish the authenticity of artefacts, while audiences reward public figures who display personal authenticity. Its opposite — falseness, imitation, or pretence — is precisely what the word exists to exclude. Because it spans both the material world (verification of objects) and the moral world (sincerity of persons), authenticity serves as a bridge between factual truth and human integrity.

"Collectors paid a premium for the painting after experts verified its authenticity."
"Museum conservators spent months confirming the manuscript's authenticity before putting it on display."

Do not use 'authenticities'; refer instead to 'instances of authenticity' or rephrase with countable nouns.
"Different cultures prize different forms of authenticity."
The word 'authenticity' comes from Greek roots meaning 'one who does a thing with his own hand' — so calling something authentic is literally crediting it as self-made.

Etymology of authenticity
Authenticity comes from the adjective 'authentic', which entered English in the late Middle Ages from Old French and directly from Latin 'authenticus', itself borrowed from Greek 'authentikos'. The Greek root relates to 'autos' (self) and a word meaning one who acts with his own hand or on his own authority. The abstract noun form arose in English by the early modern period, following the common pattern of forming '-ity' nouns from adjectives. It shares its ultimate root with words such as 'author' and 'authority', which also trace back to the same Greek source concerning origination and authorship.
