Someone may not care that Good Samaritan paid it (8)
I believe the answer is:
twopence
I believe this is a double definition.
'someone may not care that' is the first definition.
(as in 'I wouldn't give tuppence for it')
'good samaritan paid it' is the second definition.
('he took out two pence' - Luke 10:35)
(Other definitions for twopence that I've seen before include "bit of history" , "very little bread" , "Not much money" , "Low-value coin" , "Fiftieth of a pound" .)
