For most collectors, one Square Kookaburra coin is simply not enough. The addition of the Square Halfpenny completes the picture.
But as you can see from our comments above. Acquiring a Square Halfpenny is never going to be easy.
There are about 150 Square Pennies available to collectors of varying designs and varying dates. And there are, we estimate, about 12 Square Halfpennies.
And the Square Halfpenny is engaging. We have seen clients go weak at the knees when they take delivery of their Kookaburra Square Halfpenny.
It is a coin that NEVER fails to impress. It generates excitement … that so much influence can be contained in one tiny coin.
The Square Penny and the Square Halfpenny are regarded as two of Australia’s classic coin rarities along with our first silver coins, the Holey Dollar and Dump. And our first gold coins, the Adelaide Pounds.
They are highly historical and have sustained buyer interest, underpinning their investment value.
The Square Kookaburra coins were thrown into the spotlight in 1954 when Sir Marcus Clark O.B.E. sold his extensive and famous collection of Australian coin rarities.
It is on record that his 1921 Square Penny and 1921 Square Halfpenny sold for £36. Even more interesting is that in the same auction an Extremely Fine Ferdinand VII Holey Dollar sold for just over twice that amount at £72 10/-. (The investment potential of the Square Penny and Square Halfpenny lies in the fact that the Holey Dollar is now a $450,000-plus item.)
The popularity of the kookaburras continued throughout the 1960s and 1970s with extensive reporting of their appearances occurring in the then industry magazine, The Australian Coin Review.
Strong collector and investor interest in the Square Kookaburras continues to this very day.
