Coin, rare, placed in the middle (7)

Ross

I believe the answer is:

centred

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

'placed in the middle' is the definition.
(I've seen this before)

'coin rare' is the wordplay.
'coin' becomes 'cent' (cent is a kind of coin).
'rare' becomes 'red' (I can't justify this - if you can you should give a lot more credence to this answer).
'cent'+'red'='CENTRED'

Can you help me to learn more?

(Other definitions for centred that I've seen before include "Moved to the middle" , "half way across?" , "Placed in the middle" , "Positioned centrally" .)

I've seen this clue in The Telegraph.
