Coin associated with a sovereign (5)
I believe the answer is:
crown
I believe this is a double definition.
'coin' is the first definition.
(I know that crown is a type of coin)
'a sovereign' is the second definition.
(thesaurus)
'associated with' is the link.
(Other definitions for crown that I've seen before include "Visible part of a tooth" , "sporting award" , "Top of the head; coin" , "Coronet" , "Hit on the head (informal)" .)
