They're holding the Coppers' and Super's suspect? (6)

I believe the answer is:

purses

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

'they're holding the coppers'' is the definition.
The definition suggests an adverb but the answer is not.

'super's suspect?' is the wordplay.
'suspect?' is an anagram indicator (I've seen 'suspect' mean this).
'supers' anagrammed gives 'PURSES'.

'and' acts as a link.

Can you help me to learn more?
