'they' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'coin terms?' is the wordplay.
'coin' becomes 'mint' (synonyms).
'terms?' becomes 'ers' (I am not sure about this - if you are sure you should believe this answer much more).
'mint'+'ers'='MINTERS'
