Queen always surrounded by a lot of old money (9)
I believe the answer is:
guinevere
'queen' is the definition.
(King Arthur's queen)
'always surrounded by a lot of old money' is the wordplay.
'always surrounded' becomes 'vere' (I am not sure about this - if you are sure you should believe this answer much more).
'by' says to put letters next to each other.
'a lot of' means to remove the last letter (I've seen 'lots of' mean this (the majority of the word)).
'old money' becomes 'guinea' (historical type of coin).
'guinea' with its last letter taken away is 'guine'.
'vere' put after 'guine' is 'GUINEVERE'.
(Other definitions for guinevere that I've seen before include "A mistress" , "Arthur's queen" , "legendary character)" , "King Arthur's wife" , "Arthur's wife (and Lancelot's lover?)" .)
