Dole out some coppers, some coppers reportedly (8)
I believe the answer is:
dispense
'dole out' is the definition.
('dispense' can be a synonym of 'dole out')
'some coppers some coppers reportedly' is the wordplay.
'some coppers' becomes 'dis' (DIs, detective inspectors).
'some coppers' becomes 'pens' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'reportedly' becomes 'e' (I've seen this in other clues).
'dis'+'pens'+'e'='DISPENSE'
Can you help me to learn more?
(Other definitions for dispense that I've seen before include "Supply (as chemist)" , "Dish out, medicine say" , "let off?" , "Execute" , "Prepare and give out, as chemist does medicines" .)
