Hundredth of a peso (7)
I believe the answer is:
centavo
'hundredth of a peso' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for centavo that I've seen before include "money overseas" , "bit of money" , "money abroad" , "A little money" , "Small coin of Mexico, Brazil, etc" .)
