Descendant collecting coins (5)

I believe the answer is:

scion

I'm a little stuck... Click here to teach me more about this clue!

'descendant' is the definition.
(scion is a kind of descendant)

'collecting coins' is the wordplay.
'coins' can be anagrammed to 'SCION'.
However, I'm not sure how this is indicated.

Can you help me to learn more?

(Other definitions for scion that I've seen before include "Descendent - heir" , "Offshoot" , "Young shoot/twig" , "Plant shoot; descendant of a noble family;" , "Young shoot or twig" .)
