Second century article, gold-plated statuette (5)
I believe the answer is:
oscar
'statuette' is the definition.
(the golden Oscar statuette)
'second century article gold-plated' is the wordplay.
'second' becomes 's' (common abbreviation).
'century' becomes 'C' (common abbreviation).
'article' becomes 'a' (the indefinite article in English).
'gold' becomes 'or' ('or' is the heraldic name for gold).
'plated' is an insertion indicator (plated can mean covered or coated).
's'+'c'+'a'='sca'
'sca' going within 'or' is 'OSCAR'.
(Other definitions for oscar that I've seen before include "Mr Wilde - film award" , "Movie award, popularly called" , "Film-prize statuette" , "The familiar Mr Wilde, playwright" , "Some players are given this" .)
