Token putsch over working (6)
I believe the answer is:
coupon
'token' is the definition.
(thesaurus)
'putsch over working' is the wordplay.
'putsch' becomes 'coup' ('coup' can be a synonym of 'putsch').
'over' says to put letters next to each other.
'working' becomes 'on'.
'coup'+'on'='COUPON'
(Other definitions for coupon that I've seen before include "Entry form" , "Token" , "means to buy goods" , "Voucher or ticket" , "betting slip" .)
