In Lancashire it's called brass (4)

I believe the answer is:

cash

'brass' is the definition.
(I've seen this before)

'in lancashire it's called' is the wordplay.
'in' indicates the answer is hidden within the clue.
'CASH' is hidden in the letters of 'lancashire called'.

(Other definitions for cash that I've seen before include "Spondulicks" , "Hard currency" , "Singer Johnny, d. 2003" , "Till" , ""Readies"" .)

I've seen this clue in the Evening Standard.
