I believe the answer is:

mints

I'm a little stuck... Click here to teach me more about this clue!

'makes money' is the definition.
(I've seen this in another clue)

I can't explain the rest of the clue.

(Other definitions for mints that I've seen before include "Pennyroyals" , "produces coinage" , "Plants including the pennyroyal" .)

I've seen this clue in the Evening Standard.
