Notes and coins one dropped in well! (5)

I believe the answer is:
money
This clue might be a double definition.
'notes' is the first definition.
(thesaurus)
'coins one dropped in well' is the second definition.
'money' can be an answer for 'coins' (I've seen this before). I am not sure about the 'one dropped in well' bit.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for money that I've seen before include "ready" , "The 6 [NECESSARY]" , "Currency; wealth" , "Legal tender" , "Medium of exchange" .)
