These are my favorite silver coins and the only ones that I still buy annually. I have all of the 1oz issues back to 1990. I have 1 10oz, which shocked me with its size, but I never bought a 2oz or a kilo. Apparently, the Australian mint produced some years only by demand, but they sometimes have a cap of 300,000 or 500,000. This page seems to show those figures.
I don't. I've got a bunch of ASEs though, and some really nice Franklin Mint pieces celebrating British things lol. I also love my Victory in the Pacific Australian gold!
If you were impressed with the 10oz, it is certainly worth checking out the kilo. Sometimes you can catch them for a reasonable premium of $1-$2 per oz over spot (although that was more common before the 2020 spot increase).
I have a 2016 Kookaburra but that’s about it. I do like how the fields have a proof kind of look. Or at least proof like.
