Pieces of gold and silver, perhaps (8)
I believe the answer is:
elements
This clue is a double definition.
'pieces' is the first definition.
(element can mean a piece of something)
'gold and silver perhaps' is the second definition.
(I know this)
'of' acts as a link.
(Other definitions for elements that I've seen before include "Components or weather conditions" , "He and I are two" , "Essential parts or the weather" , "Component parts" , "Eg, helium and silver" .)
