Acceptable currency (5,6)

I believe the answer is:

legal tender

(Other definitions for legal tender that I've seen before include "Notes, perhaps" , "That which a creditor must accept" , "Unrefusable form of currency" , "Money which must be accepted as payment" , "Good money" .)

I've seen this clue in the Evening Standard and The Independent.
