Please radars teddy I beg of you to read this thread, it explains in detail about the NZ series
http://goccf.com/t/379889Now the coin is interesting, the die cracks if real are very interesting. Because the 3d and 6d were small and thin coins, die cracking is not unknown.
This is a fairly good coin, but I consider it overgraded. I am not sure about American grading companies, that coin is not AU55. In the British NZ grading system it is a high VF, which would translate through to the XF40 - 45 in Sheldon
The hair on the King is quite flat and there is clear wear on the cheek and trunk. Lustre looks good - but lustre survives well on NZ coins down as gFine is some cases - I am also suspecting the coin may have been cleaned but could be wrong. Still its a well above average example, most of these survive in Good to Fine condition.
All NZ coins of this vintage were made at
The Royal Mint in London.
