Hide worker's old coin
I believe the answer is:
tanner
I believe this is a double definition.
'hide worker's' is the first definition.
(I've seen this in another clue)
'old coin' is the second definition.
(historical sixpence coin)
(Other definitions for tanner that I've seen before include "One preparing leather" , "One working in hide" , ".One who cures animal hides" , "Leather worker -- old coin" , "Hide worker; old coin" .)
