Issue foreign coins (5)
I believe the answer is:
scion
'issue' is the definition.
(I've seen this in another clue)
'foreign coins' is the wordplay.
'foreign' is an anagram indicator (foreign order of the letters).
'coins' anagrammed gives 'SCION'.
(Other definitions for scion that I've seen before include "Offspring" , "Young family member" , "Young child" , "Issue" , "Offshoot" .)
