The Kookaburra Halfpenny, one of twelve examples known to collectors and this coin brilliantly struck, with lustrous satin fields and very soft antique toning.


The 1921 Square Halfpenny obverse featuring an uncrowned King George V. The legend and portrait both highly detailed.

When the Kookaburra Square Penny and Halfpenny were created, Australians were recovering from the war and determined to lessen the ties with Great Britain. The mood even filtered through to our coinage!

The Government planned to introduce a square penny and halfpenny with our native bird on the reverse. And the monarch minus his crown on the obverse!

Provocative and contentious but uniquely Australian.

Australia entered a modern age post World War I. For many Australians, it was a time for breaking out socially, of questioning and changing old values and behaviour and enjoying the good life. It was a time of great change. People forgot the old and embraced the new in an attempt to leave the hardship and struggles of the war behind them.

New technology was being created, like toasters and cars, things that today we take for granted. The fashion world was exploding, great changes were embraced in styles of dress. Australians were identifying with their own culture, keen to lessen the emotional and cultural ties with Great Britain.

Creating a new, totally Australian coinage was a part of the deal which is why the Government floated the idea of the Kookaburra Penny envisaging a coin that would be unique to Australia.

The Government's plan was to discard the British-styled penny and halfpenny and to create a coin with a typically Australian design featuring the nation's native bird, the kookaburra.

To maximise impact, a new shape was planned with the move from circular to square. And bronze was to be discarded and a new metal taken up, that of cupro-nickel.

Tests began at the Melbourne Mint in 1919 and continued for three years, ending in 1921.

Today there are about two hundred kookaburra pennies held by private collectors. And about twelve kookaburra halfpennies.
