The annual Kookaburra release from The Perth Mint is their standard bearer for silver coins, and has been since first issued in 1990. Very occasionally though, it appears struck in 99.99% pure gold. And, in 2021, that's exactly what has occurred! Issued in an uncommon Kookaburra specification as a quarter ounce, 99.99% pure gold proof coin, it is hard to imagine the national bird to be more desirable, more collectable, and yet still so attainable! Limited to a mintage of just 500, worldwide, you’d have to reckon that the 2021 1/40oz Kooka is going to fly!
