See you shortly in conversation with Penny? (6)

I believe the answer is:

copper

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

'penny?' is the definition.
(copper is a kind of penny)

I don't understand how the rest of the clue works.

(Other definitions for copper that I've seen before include "A reddish-brown metal" , "Element; butterfly" , "Metal, Cu" , "Metal - washing-machine?" , "Old policeman or reddish metal" .)

I've seen this clue in the Irish Times and the Irish Times (Crosaire).
