I'm a little stuck... Click here to teach me more about this clue!

'money' is the definition.
(I've seen this before)

I cannot understand how the remainder of the clue works.

(Other definitions for notes that I've seen before include "Stone with jottings" , "Short written messages" , "Written comments" , "eg E F G (mus.)" , "Marks on a stave" .)

I've seen this clue in the Evening Standard.
