Sold gold and cited no problem (9)
I believe the answer is:
auctioned
'sold' is the definition.
(auctioning is a kind of selling)
'gold and cited no problem' is the wordplay.
'gold' becomes 'Au' (Au is the chemical symbol for gold).
'and' says to put letters next to each other.
'problem' is an anagram indicator.
'cited'+'no'='citedno'
'citedno' with letters rearranged gives 'ctioned'.
'au'+'ctioned'='AUCTIONED'
(Other definitions for auctioned that I've seen before include "Hammered away" , "Dealt with lots" , "Idea count (anag.)" , "Disposed of lots" , "Sold to the highest bidder" .)
