tanner

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

'hide worker's' is the definition.
(I've seen this in another clue)

I don't understand the rest of the clue.

(Other definitions for tanner that I've seen before include "Leather worker -- old coin" , "Leather worker - old sixpence" , "Hide worker; old coin" , "One beating" , "He cures hides, for an old sixpence" .)

I've seen this clue in The Daily Mail.
