All good :)
Nobody's selling them yet, afaik. The full allocation of 1500 was bought before they were minted (originally slated to be 2500, but only 1000 or so were sold, so Sevin dropped the mintage down to 1500 again and they all got snapped up).
They're in transit right now, so follow #steemsilvergold and you'll see a lot of unboxing videos in the next week or so.
Travel to Australia will take a little longer, but we're used to that.
