Australian 1966 Decimal Coin Mint Marks

Due to the large number of coins required for the February 14 1966 changeover to decimal coinage in Australia several mints both here and abroad were used to produce the 1966 cupro nickel and bronze coinage. Coins were struck at the London, Perth, and Melbourne branches of the Royal Mint and at the new Royal Australian Mint in Canberra. There were no mintmarks on any of the coins to allow easy determination of which mint a coin was produced at. According to the Controller of the Mint at the time, Jim Henderson:

…it was intended that all Australian coins would be struck in the Royal Australian Mint after the initial changeover to decimals had been satisfied, it was not considered necessary to distinguish the coins by a specific mark identifying the mint of origin. There are, therefore, no mintmarks, as such, on the decimal coins.

However, it was possible (by the use of die markers) to distinguish what mints coins were minted at. These marks were disclosed by the Controller of the Mint in two letters to The Australian Coin Review in April 1967 (for the bronze 1c and 2c coins) and August 1971 (for the Cupro Nickel 5c, 10c, and 20c coins). All of the 80% silver round 50c coins were minted at the RAM in Canberra. This blog article will (eventually) be a single source of information online to allow you to identify the 1966 decimal coins by their mint of origin.

Australian 1966 20c Mint Marks

Australia 1966 20c – London Mint -no gap (left), Canberra Mint -gap (right)

The 1966 20c coin was minted at the Royal Australian Mint in Canberra (28,196,000 coins) and the London branch of the Royal Mint (30,000,000 coins). I find this coin a little tougher to pick between the two mints. The water swirl that ends in a point next to the platypus’ head on the reverse is supposed to have no gap (or a very small gap) between the swirl and the head on the London coin, and show a distinct gap on the Canberra minted coin. However if the strike is slightly weaker on the London minted coins then there can be a small gap present and the coin must be examined closely to be sure of the mint of origin.

The 1966 10c coin was minted at the Royal Australian Mint in Canberra (10,940,000 coins) and the London branch of the Royal Mint (30,000,000 coins). Distinguishing the two coins isn’t too hard and can be seen easily above. Look on the reverse of the coins for the three lyre bird feathers toward the top of the coin. The die marker is on the centre feather, on the Canberra coin the last spur of the feather has been removed. You can see this clearly on the image above, the spur is circled on the London minted coin, and the same spot (with the missing spur) circled on the Canberra minted coin.

The 1966 5c coin was minted at the Royal Australian Mint in Canberra (45,384,000 coins) and the London branch of the Royal Mint (30,000,000 coins). Distinguishing the two coins isn’t too hard and can be seen easily above. Look for the spines on the echidna’s front right shoulder, the spine circled in red above is long on the London minted coins and only about half the length on the Canberra minted coins.

Australian 1966 2c Mint Marks

Top, Canberra – No Blunted Claws, Bottom, Perth – Blunted First Claw

The 1966 2c coin was the highest mintage 1966 coin and was minted at the Melbourne branch of the Royal Mint (66,575,000 coins), the Perth branch of the Royal Mint (217,735,000 coins) and the RAM in Canberra (66,575,000 coins) . Distinguishing the mint of manufacture of this coin is done by looking at the front feet of the frill necked lizard. If the right most claw of the front right foot is blunted then the coin was minted in Perth. If the second claw from the right on the left foot is blunted then the coin was minted in Melbourne. If there are no blunted claws then the coin was minted in Canberra. The image above shows the Canberra minted coin at the top with an indicator of which claw is blunted for the Melbourne minted coin. The bottom image is of a Perth minted 2c.

The 1966 1c coin was the second highest mintage 1966 coin and was minted at the Melbourne branch of the Royal Mint (238,990,00 coins), the Perth branch of the Royal Mint (26,620,000 coins) and the RAM in Canberra (146,140,000 coins) . Distinguishing the mint that manufactured this coin is done by looking at the left-most whiskers of the possum. If the left most whisker is blunted then the coin was minted in Melbourne, if the second from the left most whisker is blunted then the coin was minted in Perth. If neither are blunted then the coin was minted in Canberra. The images above show the Canberra minted coin at the top and a Melbourne minted coin below. The image at the bottom of this article shows a Perth minted 1c coin.

1991 25th Anniversary of Decimal Currency 50 cent

Australia 1991 25th Anniversary of Decimal Currency 50c

Australia 1991 25th Anniversary of Decimal Currency 50 cent

The 14th of February 1966 was ‘C Day’, when Australia changed from the pounds, shillings, and pence system to a decimal system of dollars and cents. It was a massive event with shopping tills and calculators across the country needing to be modified or replaced, the government had to have more than a billion new coins minted and ready to be sent into circulation, and the public had to be extensively educated in the new decimal system. Preparation had begun years before with the new mint opening in Canberra in 1965. Because Australia needed so many new coins, decimal coins for 1966 were minted in London, Melbourne, Perth, and the brand new Royal Australian Mint (RAM) in Canberra. 1991 was the 25th anniversary of the introduction of decimal currency in Australia and the RAM chose to celebrate with an attractive commemorative 50 cent coin that was released into circulation.

Decimal coins in 1991 had the Raphael Maklouf portrait of Queen Elizabeth II on the obverse. The reverse of this commemorative coin was designed by RAM master sculptor Horst Hahne using the rams head from the Australian shilling which was minted from 1938 to 1963 and his own legend which reads “50 Cents : 25th Anniversary of Decimal Currency”. The rams head is a depiction of that originally sculpted by George Kruger Gray. 4,704,000 of these coins were struck in copper nickel for circulation, another 169,557 to brilliant UNC standards for mint sets, and 41,590 in proof for the 1991 proof sets. 25,000 were also struck in sterling silver for the 1991 Masterpieces in Silver set.

The 1991 25th Anniversary of Decimal Currency 50c is one of the lowest mintage circulating commemorative 50c coins and as such you don’t often see them in your change. There were still nearly 5 million of them made though, so it is by no means a scarce coin and only really worth more than face value if it is uncirculated, when it is worth $7-$10. A proof cupro nickel coin might fetch up to $20 while the sterling silver coin from the Masterpieces in Silver set can be had for $30. Interestingly security rolls of this coin are quite scarce and do fetch decent prices of $150 and up.

1982 Commonwealth Games 50c : Australian 50 Cent Coins

1982 Commonwealth Games 50 Cent Coin

1982 Commonwealth Games 50 Cent Coin

The 1982 Commonwealth Games 50c coin released to commemorate the Commonwealth Games which isĀ an elite sporting event held every 4 years and participant nations come from the Commonwealth of Nations (which was formerly the British Empire). The games have been held since 1930 (when they were known as the Empire Games) and changed name several times until 1978 when they finally became known as the Commonwealth Games. Australia had held the games twice until 1982 when they were held in Brisbane (the 12th Commonwealth Games). As a child at the time of the Brisbane Commonwealth Games I clearly remember the huge winking kangaroo, Matilda, that made it’s way around the stadium during the opening ceremony. Putting aside the memories of childhood the games in Brisbane were a very popular event in Australia, with Australia and England having an exciting head to head contest at the top of the medal tally board. To celebrate such a large sporting event the RAM issued an attractive 50c coin into circulation which can be seen above.

The obverse of the 12 sided, 15.5 gram, cupro nickel 50c coin coin bears the standard young portrait of Her Majesty as sculpted by Arnold Machin. The reverse of the coin was designed by Stuart Devlin. The reverse design shows the logo of the 1982 Brisbane Commonwealth Games over a map of Australia surrounded by icons representing 12 of the sports conducted during the games. The legend around the reverse reads “XII Commonwealth Games Brisbane 50 Cents”. 23,287,000 of the coins were struck for circulation, a further 195,000 in brilliant UNC condition for mint sets, and 100,000 were struck to proof standards for the 1982 proof sets. The coin was also struck in silver for the 1989 Masterpieces in Silver set, but was dated 1989 and had the newer Raphael Maklouf obverse.

Like the 1970 Captain Cook 50c, the 1981 Charles and Diana 50c and the 1977 Silver Jubilee 50c the 1982 Commonwealth Games 50c was hoarded away in great numbers in the hope that they would someday be worth a fortune. Tragically that day has yet to arrive and you can easily buy a nice uncirculated coin for just $4. A coin from a mint set may fetch a couple of dollars more. A pristine proof 1982 50c could fetch about $20 while the silver coin from the 1989 Masterpieces in Silver set would get about the same. If you’re lucky enough to find a circulated 1982 Commonwealth Games 50c in your change please buy yourself a very small chocolate bar with it because it’s worth exactly 50c!

1977 Silver Jubilee 50c : Australian 50 Cent Coins

1977 Silver Jubilee 50 Cent

1977 Silver Jubilee 50 Cent

Queen Elizabeth II ascended to the throne of the United Kingdom and the Commonwealth in 1952 after the death of her father George VI. Interestingly she was not actually crowned until 1953. 1977 was the 25th anniversary of her ascension (the ‘silver jubilee’),and celebrations were held throughout the UK and the British Commonwealth, with the official day of celebration set as February 6, 1977. The Royal Australian Mint joined in on the party with the released the 1977 50c, a commemorative 12 sided, 15.5 gram, cupro nickel coin for general circulation.

The obverse of the coin bears the standard young portrait of Her Majesty as sculpted by Arnold Machin. The reverse of the coin (like all other decimal coins up until 1986) was designed and sculpted by Stuart Devlin. A typical royal design by Devlin (similar to some of his other work in silver) it comprises 25 crowns in a ring around a central device and the legend “Silver Jubilee 50 Cents”. 25 million of the coins were struck for circulation, a further 128,000 in brilliant UNC condition for mint sets, and 55,000 were struck to proof standards for the 1977 proof sets. The coin was also struck in silver for the 1989 Masterpieces in Silver set, but was dated 1989 and had the newer Raphael Maklouf obverse.

Like many of the early commemorative 50c coins the Silver Jubilee coins were hoarded away in great numbers, and you can easily buy a nice uncirculated coin for just $4 or $5. A coin from a mint set may fetch a couple of dollars more. A pristine proof 1977 50c could fetch $20 to $30 while the silver coin from the 1989 Masterpieces in Silver set would get about the same. A circulated 1977 Silver Jubilee 50c coin is worth, somewhat sadly, 50c.

1981 Royal Wedding Charles and Diana 50c

Australia 1981 Royal Wedding Charles and Diana 50c

Australia 1981 Royal Wedding Charles and Diana 50c

Prince Charles is the eldest child of Queen Elizabeth II, first in line to the throne and potentially the next King of England and the Commonwealth. Nuptials between Prince Charles and Lady Diana Spencer took place on 29th July 1981 (which was named a national holiday in celebration) in front of a worldwide TV audience of 750 million people. It was labelled a fairytale wedding as Diana was the first British commoner to marry an heir to the throne since the 1500’s. The couple were dominant public figures constantly under scrutiny from royal watchers. They later had 2 children, 2nd in line to the throne Prince William and 3rd in line Prince Harry.

In Australia up until as close to the event as June 1981 it wasn’t clear that a commemorative issue was even going to be released with industrial action at the Royal Australian Mint affecting coin issues and the minting process. However, after keeping their plans under wraps the RAM finally announced that to celebrate this royal marriage the Royal Mint in Wales was to strike a commemorative 50c piece to circulate in Australia. Designed by Stuart Devlin the reverse of this coin features profiles of Charles and Diana (known as jugate) facing left with the legends reading “HRH The Prince of Wales and Lady Diana Spencer Fifty Cents”. This was an official design given the Royal seal of approval by the Queen but is affectionately known to collectors as the Chuck and Di 50c.

The obverse bears the Arnold Machin portrait of a young Queen Elizabeth II (used from 1966 through to 1984). 20 million of these 15.5 gram cupro-nickel coins entered circulation but they are not that easy to find in your change as a lot have been hoarded in money boxes and jars. It’s not uncommon to find high grade coins because if this hoarding and they don’t gain much premium if any over their face value of 50c.

These coins were restruck in Canberra as a silver proof version which was included in the 1989 Masterpieces in Silver Sets.
