Good antique piece of tableware initially declared secure (4-6)

I believe the answer is:

gold-plated

'secure' is the definition.
(gold-plated can mean secure or reliable)

'good antique piece of tableware initially declared' is the wordplay.
'good' becomes 'g' (abbreviation).
'antique' becomes 'old' (similar in meaning).
'piece of tableware' becomes 'plate'.
'initially' suggests taking the first letters.
The initial letter of 'declared' is 'd'.
'g'+'old'+'plate'+'d'='GOLD-PLATED'

I've seen this clue in The Guardian.
