Valuable brick home acquired (5)
I believe the answer is:
ingot
'valuable brick' is the definition.
(I've seen this in another clue)
'home acquired' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'acquired' becomes 'got' ('get' can be a synonym of 'acquire').
'in'+'got'='INGOT'
(Other definitions for ingot that I've seen before include "A lump of metal like gold" , "E.g. a gold bar" , "Mass of cast metal" , "Block (of steel, gold, etc)" , "Gold Stick" .)
