Strike for money (5)
I believe the answer is:
pound
I believe this is a double definition.
'strike' is the first definition.
(thesaurus)
'for money' is the second definition.
(I've seen this before)
(Other definitions for pound that I've seen before include "Author" , "Ezra --, US poet" , "Batter" , "L" , "Hit repeatedly; coin" .)
