Coin is remote object (8)
I believe the answer is:
farthing
'coin' is the definition.
(farthing is a kind of coin)
'remote object' is the wordplay.
'remote' becomes 'far' (similar in meaning).
'object' becomes 'thing' (an object is a thing or item).
'far'+'thing'='FARTHING'
'is' is the link.
(Other definitions for farthing that I've seen before include "Former British coin" , "One quarter of an old penny: measure of land in old England" , "Smallest coin once" , "Old piece" , "of negligible value" .)
