Quarter-penny (8)
I believe the answer is:
farthing
This clue is a double definition.
'quarter' is the first definition.
(thesaurus)
'penny' is the second definition.
(thesaurus)
(Other definitions for farthing that I've seen before include "Former British coin" , "Old British coin" , "One quarter of an old penny: measure of land in old England" , "It used to be one quarter of a penny" , "Obsolete small coin" .)
