Casino token; golf shot (4)
I believe the answer is:
chip
This clue is a double definition.
'casino token' is the first definition.
(I've seen this in another clue)
'golf shot' is the second definition.
(chip is a kind of golf shot)
(Other definitions for chip that I've seen before include "Sliver of wood or piece of potato" , "Gambling token" , "Murphy sliced" , "Golf shot; item of fried food" , "Maybe silicon or potato" .)
