Not bad it is a nice coin!
I love me the gothics - it is not that bad, I would say its full VG, these coins had notoriously high relief on the shields and thus they can be worn flat by Fine and quite dull at VF.
Plus you have a historic work of art there, they were the culmination of the Victorian obsession with medievalism (You know like all those Victorian mansions with pointed windows).
Loving Halfcrowns. British and Commonwealth coins 1750 - 1950 and anything Kiwi.
If it's round, shiny and silvery I will love it.
