Note in Vogue held by gambler (4)
I believe the answer is:
chip
'vogue held by gambler' is the definition.
I can't tell whether this definition defines the answer.
'note in' is the wordplay.
'note' becomes 'c' (musical note).
'in' becomes 'hip' (both can mean fashionable).
'c'+'hip'='CHIP'
(Other definitions for chip that I've seen before include "Gaming counter" , "Piece off block (or on shoulder?)" , "Fragment of wood or potato" , "On the shoulder, it's a sign of resentment" , "Gambling counter; golf shot" .)
