Stipulated coin, without condition, note (9)
I believe the answer is:
specified
'stipulated' is the definition.
('specify' can be a synonym of 'stipulate')
'coin without condition note' is the wordplay.
'coin' becomes 'specie' (term for coined money).
'without' indicates putting letters inside ('without' can be similar in meaning to 'outside').
'condition' becomes 'if' (as in 'a big if').
'note' becomes 'D' (musical note).
'specie' enclosing 'if' is 'specifie'.
'specifie'+'d'='SPECIFIED'
(Another definition for specified that I've seen is " Clearly identified".)
