Coin occupying hole (6)

Ross

I believe the answer is:

invent

'coin' is the definition.
(I've seen this before)

'occupying hole' is the wordplay.
'occupying' becomes 'in' (I've seen this in other clues).
'hole' becomes 'vent' (vent is a kind of hole**).
'in'+'vent'='INVENT'

(Other definitions for invent that I've seen before include "Discover Devise, concoct" , "Cook up" , "Create like Edison" , "Make up (something false)" , "Coin" .)

I've seen this clue in The Times.
