Bet here as coin thrown about (6)
I believe the answer is:
casino
'bet here' is the definition.
(a place for betting)
'as coin thrown about' is the wordplay.
'thrown' is an anagram indicator.
'about' means one lot of letters goes inside another.
'coin' anagrammed gives 'cino'.
'as' put within 'cino' is 'CASINO'.
(Other definitions for casino that I've seen before include "Building for gambling" , "gambling-place" , "Gambling emporium" , "Las Vegas establishment" , "Gaming house" .)
