Some paper money of distinction? (4)
I believe the answer is:
note
I believe this is a double definition.
'some paper money' is the first definition.
(note is a kind of paper money)
'distinction?' is the second definition.
(I know that distinction can be written as note)
'of' is the link.
(Other definitions for note that I've seen before include "Be mindful of" , "Short written message" , "Tone of distinction" , "Quaver, say" , "Bill" .)
