Money a distant object for one worth nothing (5,8)

I believe the answer is:
brass farthing
'for one worth nothing' is the definition.
I can't judge whether this defines the answer.
'money a distant object' is the wordplay.
'money' becomes 'brass' (brass can informally mean money).
'a distant' becomes 'far' (I've seen this before).
'object' becomes 'thing' (an object is a thing or item).
'brass'+'far'+'thing'='BRASS FARTHING'
Can you help me to learn more?
(Other definitions for brass farthing that I've seen before include "It's hardly worth anything" , "Coin of minimal value" , "Something of minimal value" .)
