Tribute paid in silver blocks (6)
I believe the answer is:
homage
'tribute paid' is the definition.
(an homage pays tribute to someone)
'in silver blocks' is the wordplay.
'in' becomes 'home' ('he's in' can mean 'he's home').
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'blocks' is an insertion indicator (to block can mean to plug a gap in something).
'home' placed around 'ag' is 'HOMAGE'.
(Other definitions for homage that I've seen before include "Reverent regard" , "Public tribute" , "Formal expression of loyalty to a ruler - pay it" , "Public show of respect" , "Honour or respect shown publicly" .)
