Great money (8)
I believe the answer is:
sterling
I believe this is a double definition.
'great' is the first definition.
(I know that sterling is a more specific form of the attribute great)
'money' is the second definition.
(I know that sterling is a type of money)
(Other definitions for sterling that I've seen before include "Genuine - money" , "Excellent, first-class" , "Excellent - British money" , "Of the highest qualiy" , "Ringlets being of solid worth" .)
