Royal Australian Mint, Canberra, Australia (1965-date)


To mark the 40th anniversary in 2006 of the transition to decimalisation in Australia the Royal Australian Mint has revisited the original 50c coin in shape and composition. Only available in the Eight Coin Year Proof Set issued for 2006 was this 31.51mm round 50 cent made from 80% silver and 20% copper. It weighs slightly less than it's dodecagonal cousins at 13.28grams. Also included in the proof set was a special 1 and 2 cent coin. This 50 cent coin was shaped round just like the first 50 cent coin in 1966 but has the Ian Rank Broadley Obverse instead of the original Arnold Machin Obverse .

The same silver coin was also issued in the 2010 Heritage set which is quite rare at only 400 minted and also issued in the "In Come the Dollars in Come the Cents" 2016 set.

All other 50 cent coins since 1966 up to current date were made as Dodecagonal (12-sided) coins
(Except for the 14 sided Lunar Year of the Rooster etc 50 cent coins.)

There was also another round silver 50 cent coin issued by the RAM in 2006. It was part of the Fine Silver Proof Set and it had the original Arnold Machin second portrait of Queen Elizabeth II. See link below.
