Poker token (4)
I believe the answer is:
chip
'poker token' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for chip that I've seen before include "Gaming counter" , "Piece of old block, potato, etc" , "Gambling token" , "Sliver of wood or piece of potato" , "Piece of fried potato" .)
