Aust. coins were made of sterling silver except pennies and Ā½ pennies (copper)and were based on silver value/weight till 1946 and when silver went up they keep the same size but made them out of 50% silver. On Feb 1966 they changed over to copper/nickel and still keep the same size. They also released a 50 cent 80% silver piece and were taken out of circulation in no time because the silver price went up soon after release.Ā Diameter:Ā 31.51 mm At decimal change over the copper coins were reduced in size to a fraction of the weight/size.Ā 

The original, round, 50-cent 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silver price became higher, the coin's bullion value became more valuable than its face value; so that version was withdrawn from circulation and replaced with the dodecagonalĀ cupro-nickelĀ version.Ā 

Diameter 31.65 (across flats[1])Ā mm

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