This was Australia's first square decimal coin.
Although this is definitely the first-ever square coin struck officially in Australia, the designs hark back to a very rare series of pattern coins that were contemplated by senior figures in the Commonwealth Government following World War I.
The Kookaburra Pennies are among Australia's rarest and most desirable coins - the design of the Perth Mint's 2002 half-ounce silver coin draws heavily on them.
The innovative shape and packaging saw this coin in strong demand right around the world, they remain popular with collectors to this day.
This coin remains in the original capsule it was sold in.
