![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
slot
'coin taker' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for slot that I've seen before include "Space for coin or programme" , "Long narrow slit" , "Small opening, for a coin say" , "Long narrow opening" , "Scheduled time - hierarchical position" .)
