Brand-new moneymaker (4)
I believe the answer is:
mint
I believe this is a double definition.
'brand-new' is the first definition.
(thesaurus)
'moneymaker' is the second definition.
(a mint is a coin factory)
(Other definitions for mint that I've seen before include "Culinary herb" , "packet" , "sweet herb" , "Huge sum of money" , "Aromatic plant - make money" .)
