Trump's old mate gives money (5)
I believe the answer is:
pence
'money' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for pence that I've seen before include "Copper coins" , "Small-value coins" , "Small quantity of money" , "Small sum of money" , "Fractions of a pound" .)
