Old coin, Chinese one with note in typical moneybox? (7)
I believe the answer is:
pfennig
'old coin' is the definition.
(pre-Euro German coin)
'chinese one with note in typical moneybox?' is the wordplay.
'chinese one' becomes 'enn' (I can't explain this - if you can you should believe this answer much more).
'with' is a charade indicator (letters next to each other).
'note' becomes 'f' (musical note).
'in' is an insertion indicator.
'typical moneybox?' becomes 'pig' (piggy bank).
'enn' after 'f' is 'fenn'.
'fenn' inserted within 'pig' is 'PFENNIG'.
(Other definitions for pfennig that I've seen before include "One / One-hundredth of a Deutschmark" , "Approximately two point two zero five pounds" , "Hundredth of an old Deutschmark" , "old rhino" , "Old German monetary unit" .)
