Bad lot left dud coins in Birmingham suburb (6,9)

I believe the answer is:

sutton coldfield

'birmingham suburb' is the definition.

'bad lot left dud coins' is the wordplay.
'bad' indicates an anagram.
'lot'+'left'+'dud'+'coins'='lotleftdudcoins'
'lotleftdudcoins' anagrammed gives 'SUTTON COLDFIELD'.

'in' is the link.

(Another definition for sutton coldfield that I've seen is " somewhere in the Midlands".)

I've seen this clue in The Times.
