Excellent money (7)
I believe the answer is:
capital
This clue is a double definition.
'excellent' is the first definition.
(thesaurus)
'money' is the second definition.
(I've seen this before)
(Other definitions for capital that I've seen before include "Havana, say" , "A country's main city" , "city such as London" , "City - finance - very good" , "Fantastic!" .)
