Center struck on type 1 blank. Broadstruck on obverse, struck in collar on reverse. Much scarcer than an off-center struck.
Here is a Great Britain 3-pence obverse die cap error coin I purchased recently. It has a nice cup shape, although one side is way deeper than the other.
Crusty old coins are hard to come by as NZ coinage was basically British coinage until 1967. As for dilapidated old NZ - there are pretty run down old small towns similar to what you find everywhere in the world. People move to the cities and things are left to rot. This will give you an idea - Ohura
Ive had a loads of people look at the 1909 which I agree has various signs of damage but a few experts commented about the fact that the D is still visible at the bottom of the gouge so Its gone back into my possible errors box.
I bought them that way...actually, my boyfriend did. He works at a pawn shop and brought them home for me. He brings me all kinds of cool stuff from work, plus, the owner is an avid coin collector and has been for years and years. I would LOVE to see his collection!
