I had a gold piece with a certain image (4)
I believe the answer is:
idol
'certain image' is the definition.
'idol' can be an answer for 'image' (idol is a kind of image). I am not sure about the 'certain' bit.
'i had a gold piece' is the wordplay.
'had' is a charade indicator (letters next to each other).
'a gold piece' becomes 'dol' (I am not sure about this - if you are sure you should believe this answer much more).
'i'+'dol'='IDOL'
'with a' is the link.
Can you help me to learn more?
(Other definitions for idol that I've seen before include "Film star" , "A matinee -- is a handsome actor" , "Hero, star" , "Superstar; graven image" , "Who's greatly respected" .)
