G'day,
New Zealand introduced its own silver coinage in 1933.
Bronze coins followed in 1940.
So, this coin is the first of its type.
New Zealand went decimal in 1967.
The bird on the penny is a "Tui"; see:
http://en.wikipedia.org/wiki/Tui_(bird)All of the design elements are readily apparent, but I can see a few dings on the obverse. I don't like the gunk in the "4": if it were mine, I'd probe it with a bamboo toothpick - gently.
I'd say its VF+.
A nice coin, that I'd be happy to have in my collection.
