Top money, once? (5)

I believe the answer is:

crown

This clue is a double definition.

'top' is the first definition.
(I know that crown is a type of top)

'money once?' is the second definition.
(former UK coin)

(Other definitions for crown that I've seen before include "Royal headdress" , "sporting award" , "Old coin; top of tree" , "piece of tooth" , "Symbol of royalty" .)

I've seen this clue in the Evening Standard.
