Money bet on gorilla (10)

Ross

I believe the answer is:

silverback

'gorilla' is the definition.
(silverback is a type of gorilla)

'money bet on' is the wordplay.
'money' becomes 'silver' (as in pieces of silver).
'bet' becomes 'back' (I've seen this before).
'on' is a charade indicator (letters next to each other).
'silver'+'back'='SILVERBACK'

(Another definition for silverback that I've seen is " gorilla?".)

I've seen this clue in The Guardian.
