I believe the answer is:
cent
'money' is the definition.
(eg denomination of dollars)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for cent that I've seen before include "One 100th of a dollar" , "100th of a euro" , "Small amount of money" , "Small US coin" , "One-hundredth of a currency" .)
