'more or less antique silver' is the definition.
I can't judge whether this defines the answer.

'gold' is the wordplay.
I cannot really understand how this works, but
'gold' could be 'or' ('or' is the heraldic name for gold) and 'or' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
