Young member of the family squandering coins (5)

I believe the answer is:

scion

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

'young member of the family' is the definition.

'squandering 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 "Coins (anag)" , "Offspring" , "Plant shoot; descendant of a noble family;" , "Young family member" , "Young shoot or twig" .)

I've seen this clue in The Irish Independent.
