This 1970 Fifty cents piece is a good strong example and has been in my personal collection for more than 30 years.

It has been lightly circulated and makes a great addition to any coin collection.

The reverse by Stuart Devlin depicts Captain James Cook and a map of Australia showing a dotted line that follows his route along the eastern seaboard of Australia in 1770. Cook’s claim to be the first to find Australia has long since been over thrown with other European explorers beating him to the drop by several hundred years.

It was the first time we saw a 12 sided (dodecagon) coin in Australia with a design other than the coat of arms. The 12 sided design has only been superseded once when the RAM released the 14 sided version (tetra decagon) in 2012 which bore the Year of the Dragon design.

It is one of the largest general circulation coins in the world.

The coin is still a great little piece of Australian history and every coin collection should have at least one example.

The twelve-sided Australian fifty-cent piece is the third-largest denomination coin of the Australian dollar and the largest under a dollar. It is the only 12 sided coin of its size in the southern hemisphere. It was introduced in 1969 to replace the round fifty-cent coin issued in 1966.

The original, round, 50c coin was made of 80% silver and 20% copper; but as the value of a free-floating silver price became higher, the coin’s bullion value became more valuable than its face value; so that version was withdrawn from circulation and replaced with the dodecagonal cupro-nickel version.

It is by diameter the largest Australian coin currently issued and second largest after the Crown of 1937–38. It is also the heaviest Australian coin in common circulation. Many commemorative designs have been issued, the large size allowing for detailed content.
