Money once made from fake tapes about Spain (6)
I believe the answer is:
peseta
'money once' is the definition.
(former Spanish currency)
'fake tapes about spain' is the wordplay.
'fake' is an anagram indicator (I've seen this in other clues).
'about' means one lot of letters goes inside another.
'spain' becomes 'e' (abbreviation for Espana).
'tapes' with letters rearranged gives 'pesta'.
'pesta' enclosing 'e' is 'PESETA'.
'made from' is the link.
(Other definitions for peseta that I've seen before include "little cash is required" , "Formerly, unit of Spanish money" , "Spanish coinage" , "Pre-Euro Spanish currency" , "Old Spanish unit of money" .)
