I don't have the 1/2 Crown but I can easily get one for you if no one else can provide it.
I have the crown if you want it
There is one NZ coin I am after but I don't think it will be easy to get. It is a 2012 Silver Endeavour 50 cent, it is part of a very limited number set. I love the design and have it in normal, prooflike and proof. All I need is the silver type now.

I don't have an extra Coronation Crown but I've got several dates of both the penny and half crown in the grades you seek. I'd prefer to trade rather than sell but I don't really collect any antipodean stuff. Got anything interesting? If not, you're welcome to them until the day you turn up something.
Non illegitimis carborundum est. Excellent advice for all coins.

Yeah that's the one, the problem is I do not really have any love for the rest of them apart from the 50 cent Endeavour.
I think it will end up far higher than I would want to part with for the sake of a single coin.
I will get the 1937 Crown off to you tomorrow, and it looks like the others you seek are covered from the other replies here.
As Phil said, sort it at a later date as I too am not interested in payment, I might spot something from your neck of the woods at a later date or someone might split the Endeavour set! .
