Gathers spare change (5)
I believe the answer is:
reaps
'gathers' is the definition.
(reaping is a kind of gathering)
'spare change' is the wordplay.
'change' is an anagram indicator.
'spare' is an anagram of 'REAPS'.
(Other definitions for reaps that I've seen before include "Gleans or harvests" , "Harvests (a crop)" , "crops" , "Harvests with strange spear" , "Cuts, gathers grain" .)
