Australian gold coins are made from various metals, including copper, aluminium, and nickel. Gold one-dollar and two-dollar coins were introduced in the 1980s, with the one-dollar coin replacing the banknote of the same value in 1984, and the two-dollar coin following suit in 1988. These coins have a gold colour but are not made of gold. The Royal Australian Mint also produces commemorative gold coins, such as the 1980-1994 gold two-hundred-dollar coin series, which are legal tender and can be used as currency. Australian gold coins, such as the Perth Mint Gold Coins and the Australian Kangaroo Gold Coins, are known for their quality and annually changing designs. These coins are struck in 99.99% pure gold and are sought after by investors and enthusiasts alike.

Australian gold coins are not pure gold
The Australian gold coins produced by the Perth Mint are made from 99.99% pure gold. These coins are known for their quality and annually changing reverse designs. The most famous of these are the Australian Gold Kangaroos, which were first minted in 1989 and are recognised globally for their annually changing designs featuring Australia's most famous animal. The Perth Mint takes extra care to package each gold coin in plastic discs.
The Australian Dollar was first announced in 1963 and the coins were introduced in 1966. At this time, the one and two-dollar coins were not included. The dollar was equivalent in value to 10 shillings (half a pound) in the former currency. The original 50-cent piece was worth more than its currency value due to its metal content of 80% silver and 20% copper. This led to the public melting their coins and selling the raw materials for more than the coins were worth.
Since the introduction of the Australian Dollar, there have been four different effigies of Queen Elizabeth II used on the obverse of the coins. Following the Queen's death, new coins began to be minted with King Charles III on the obverse. The $1 coin was the first to change over, with the remaining denominations to be changed based on bank demand.

Australian dollar coins introduced in 1966
Australian dollar coins were introduced on 14 February 1966, although they did not initially include one-dollar or two-dollar coins. The dollar was equivalent in value to 10 shillings, or half a pound, in the former currency. The first dollar coins were made from silver, with nearly 10.6 grams of silver in every coin.
The one-dollar coin was eventually introduced on 14 May 1984, with a design featuring five kangaroos, chosen from submissions by the designer Stuart Devlin. The two-dollar coin was also introduced in the 1980s, and is smaller in diameter than the one-dollar coin, but thicker. These "gold" coins were made from aluminium bronze.
The Royal Australian Mint has released many collectable coins, including the 1980–1994 gold two-hundred-dollar coin series. Collectable coins are all legal tender and can be used directly as currency or exchanged for "normal" coinage at a bank.
Today, Australian one and two-dollar coins are primarily made from aluminium and copper.

50 cent coins withdrawn in 1967 and 1968
Australian gold coins, such as the one and two-dollar coins, are primarily made from aluminium and copper. On the other hand, the 50 cent coin, which is the focus of this discussion, has undergone changes in composition and design since its introduction.
The original 50 cent coin, introduced in February 1966, was made from 80% silver and 20% copper. This coin featured the Commonwealth Coat of Arms and was round in shape. However, due to rising silver prices, the value of the metal content exceeded the face value of the coin. As a result, the production of this silver 50 cent coin was suspended in March 1968, with the coins being withdrawn from circulation.
The decision to withdraw the 1966 round 50 cent coin was influenced by two primary factors. Firstly, the increasing value of silver made it uneconomical to continue producing the coins. Secondly, there was confusion due to the similarity in size between the circular 50 cent and the 20 cent coin. This prompted the consideration of not only changing the materials but also exploring different shapes for the new 50 cent coin.
In 1969, a new 50 cent coin was introduced to replace the withdrawn round coin. The new coin had a dodecagonal (12-sided) shape and was made from cupro-nickel, a combination of copper and nickel. This change in composition and design addressed the issues of metal value and coin differentiation. The 50 cent coin remains the largest and heaviest Australian coin in common circulation.
It is worth noting that the withdrawal of coins due to metal value concerns is not an isolated incident. For example, in 1992, the 1 and 2 cent coins were removed from circulation as their production costs no longer matched their value. This highlights the ongoing need to ensure that the composition and value of coins remain aligned to prevent economic losses and maintain the stability of the currency system.

One- and two-dollar notes replaced by coins
Australian one- and two-dollar notes were replaced by coins due to the longer service life and cost-effectiveness of coins. The one-dollar note was replaced by a gold-coloured coin in 1984, while the two-dollar note was replaced by a gold-coloured coin on 14 June 1988. The one- and two-dollar coins are primarily made from aluminium and copper.
The Australian two-dollar note was introduced in 1966 due to decimalisation, to replace the £1 note, which had a similar green colour. The note featured a watermark of Captain James Cook in the white field, which was also used in the last issue of pound banknotes. There was also a metallic strip, initially near the centre of the note, which was moved to the left side in 1976.
The one-dollar notes are still incredibly popular with collectors, decades after they were replaced. Demand for one-dollar notes skyrocketed when production of the one-dollar coin commenced, and many Australians set them aside "for the kids" so they could see what was used before coin-operated machines became widespread.
The two-dollar coin's introduction in 1988 was a poignant event for many Australians. While many people kept some notes aside for their children, most of the two-dollar notes still in existence were printed in the mid-1980s and are not in mint condition. Early two-dollar notes in mint condition are much rarer and are well worth collecting.

Australian gold coins feature the Queen
Australian gold coins are not actually made of gold. The one and two-dollar coins introduced in the 1980s are made of 2% nickel, 6% aluminium, and 92% copper. They were introduced to replace the one and two-dollar banknotes. The one-dollar coin was introduced in 1984, while the two-dollar coin was introduced in 1988.
The Royal Australian Mint announced that, following the death of Queen Elizabeth II in 2022, it would produce one million $1 coins bearing King Charles' face in 2023. The new effigy will fully replace a temporary memorial effigy of Queen Elizabeth II by May 2024. Newer coins will feature a picture of King Charles III.
The Perth Mint takes extra care to package each gold coin in plastic discs. Australian gold coins are recognised for their annually changing reverse designs, a rarity in modern minting. Australian gold coins are popular among investors and enthusiasts for their appearance and attractive pricing.
