I believe the answer is:

unsociable

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

'disinclined to associate' is the definition.
I can't tell whether this definition defines the answer.

'sort of usable coin' is the wordplay.
'sort of' indicates anagramming the letters.
'usable'+'coin'='usablecoin'
'usablecoin' with letters rearranged gives 'UNSOCIABLE'.

'with a' acts as a link.

Can you help me to learn more?

(Other definitions for unsociable that I've seen before include "Hermit-like" , "Withdrawn" , "cold" , "hostile" .)

I've seen this clue in the Sydney Morning Herald.
