Where to sell gold coin crooked tenor smuggled? (7)
I believe the answer is:
auction
'where to sell' is the definition.
(I know this)
'gold coin crooked tenor smuggled?' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'crooked' indicates anagramming the letters (a crooked or disrupted version of the letters).
'tenor' becomes 't'.
'smuggled?' is an insertion indicator.
'coin' is an anagram of 'cion'.
'cion' going around 't' is 'ction'.
'au'+'ction'='AUCTION'
(Other definitions for auction that I've seen before include "Caution about method of sale" , "Public sale at which bids are made" , "Competitive sale" , "Public sale to highest bidders" , "Public sale with lots" .)
