City servant taking coffer to the Queen (10)

Ross

I believe the answer is:

manchester

'city' is the definition.
(Manchester is an example)

'servant taking coffer to the queen' is the wordplay.
'servant' becomes 'man' (man is a kind of servant).
'taking' is a charade indicator (letters next to each other).
'coffer' becomes 'chest' (I've seen this before).
'to the queen' becomes 'er' (Elizabeth Regina).
'man'+'chest'+'er'='MANCHESTER'

(Other definitions for manchester that I've seen before include "English city" , "City of NW England" , "MUFC" , "Endurance - it's them (anag)(10.6)" , "City of the Halle Orch." .)

I've seen this clue in The Independent.
