Small change for Old Bill? (7)
I believe the answer is:
coppers
'small change for old bill?' is the definition.
I can't judge whether this definition defines the answer.
'small change for old bill?' is the wordplay.
'small change' becomes 'copper' (low-value coinage).
'for' is a charade indicator (letters next to each other).
'old bill?' becomes 's' (I can't explain this - if you can you should believe this answer much more).
'copper'+'s'='COPPERS'
Can you help me to learn more?
(Other definitions for coppers that I've seen before include "Old pennies and policemen" , "Receptacles" , "hardly any 11 [LOLLY]" , "loose change?" , "The boys in blue (slang)" .)
