Antique object (5)
I believe the answer is:
relic
'antique object' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for relic that I've seen before include "Memento; souvenir" , "Object surviving from the past" , "Ancient artefact" , "Personal saintly memorial" , "item of historic interest" .)
