Descendant of different coins (5)
I believe the answer is:
scion
'descendant' is the definition.
(I know that scion is a type of descendant)
'different coins' is the wordplay.
'different' is an anagram indicator (letters placed in a different order).
'coins' is an anagram of 'SCION'.
'of' acts as a link.
(Other definitions for scion that I've seen before include "Young shoot or twig" , "Young family member" , "Offshoot" , "Offspring" , "Branch" .)
