The money's very good (7)
I believe the answer is:
capital
I believe this clue is a double definition.
'the money's' is the first definition.
(I've seen this before)
'very good' is the second definition.
(thesaurus)
(Other definitions for capital that I've seen before include "Kabul or Harare?" , "Most important city" , "Major city - investment - great!" , "A country's main city" , "Upper case city" .)
