Price of a ring? (4)

I believe the answer is:

toll

I believe this clue is a double definition.

'price' is the first definition.
(I know that price can be written as toll)

'a ring?' is the second definition.
(ring a bell)

'of' acts as a link.

(Other definitions for toll that I've seen before include "Fee for road/bridge" , "What sounds" , "Peal, chime" , "Bridge or road tax" , "Charge for passage" .)

I've seen this clue in the Evening Standard.
