What You'll Learn
Australian 5-cent coins are 25% nickel
The 5-cent coin is the smallest coin and the lowest denomination or value in Australia. The 1- and 2-cent coins were removed in 1992, and the 5-cent coin is now the smallest denomination. The 5-cent coin is often referred to as a ""nickel" by Canadians and Americans. However, in Australia, it is typically called a "five-cent piece" or "five-cent coin".
The Royal Australian Mint produces the 5-cent coin, and it has been minted by the Royal Mint in London, the Royal Canadian Mint, and the Royal Mint, Llantrisant. The composition of the 5-cent coin is 75% copper and 25% nickel, which gives it a silver colour. This is in contrast to the gold-coloured $1 and $2 coins, which contain 2% nickel, 6% aluminium, and 92% copper.
The 5-cent coin is one of the "silver" coins in Australia, which also include the 10-cent, 20-cent, and 50-cent coins. These coins are not actually made of silver but are a cupro-nickel alloy. Over time, these coins can develop a ""rust-like" coating, which is likely copper oxide. This occurs when the coins are exposed to chemicals that break down the nickel, leaving the copper behind.

10, 20 and 50-cent coins are also 25% nickel
Australian coins are made from metals such as copper, aluminium, and nickel. The five-cent coin is made of 75% copper and 25% nickel. The 10, 20, and 50-cent coins are also made of 75% copper and 25% nickel. These coins are silver in colour. The one and two-dollar coins are gold in colour and are made of 92% copper, 6% aluminium, and 2% nickel.
The five-cent coin was first introduced with decimal currency on 14 February 1966. All of the first issue of five-cent coins in 1966 were produced at the Royal Mint in London. The original reverse design of the echidna on standard circulating coins has not been changed since the introduction. The one-dollar coin was introduced in 1984, and the two-dollar coin in 1988, both to replace banknotes of the same value.
The one, two, one-cent, and two-cent coins are no longer in circulation. The one and two-cent coins were removed in 1992 due to the metal exceeding face value. The five-cent coin is now the smallest coin and the lowest denomination or value.

1 and 2-cent coins are 0.5% nickel
Australia's 1c and 2c coins were traditionally called "copper" coins, although they are actually made of an alloy of copper and zinc. The 1c coin is composed of 97% copper, 2.5% zinc, and 0.5% tin, while the 2c coin has the same composition, but with 0.5% tin instead of 0.5% nickel. These coins were removed from circulation in 1992 due to the metal exceeding face value.
The 5c, 10c, 20c, and 50c coins are often referred to as "silver" coins, but they are made of 75% copper and 25% nickel. The 5c coin, which was first introduced in 1966, features an echidna design on its reverse side, which has remained unchanged since its introduction.
The $1 and $2 coins are gold in colour and were introduced in the 1980s. They are composed of 92% copper, 6% aluminium, and 2% nickel. The $1 coin was introduced in 1984 to replace the banknote of the same value, while the $2 coin was introduced in 1988.

$1 and $2 coins contain 2% nickel
The $1 and $2 coins in Australia are gold-coloured, but they are not made of gold. They are made from a combination of metals, including 2% nickel, 6% aluminium, and 92% copper.

The 5, 10, 20, and 50-cent coins in Australia are silver-coloured, but they are not made of silver either. The 5, 10, 20, and 50-cent coins are made of 75% copper and 25% nickel. The 5-cent coin, which was first introduced in 1966, features an echidna designed by Stuart Devlin. The 50-cent coin used to be circular but was changed to have 12 flat sides so that it would not be confused with the 20-cent coin.
The 1-cent and 2-cent coins, which were removed from circulation in 1992, were traditionally called "copper" coins, although they were actually made of an alloy of 97% copper, 2.5% zinc, and 0.5% tin. Over time, these coins would develop a rust-like coating, which was possibly due to the formation of copper oxide.
Nickel is a hard, silver-white metal with a high melting point and strong resistance to low temperatures. When mixed with other metals, nickel creates alloys that are strong, rust-resistant, and can be easily shaped. Nickel is rarely found in its pure form in the Earth's crust but is often found in combination with other metals, such as iron, in nickel sulfide deposits.

Australian coins are made from cupro-nickel
Australian coins are made from a variety of metals, including cupro-nickel. The 5, 10, 20, and 50-cent coins are silver in colour, while the one and two-dollar coins are gold in colour. However, none of the coins are made of silver or gold. The 5, 10, 20, and 50-cent coins, often referred to as "silver" coins, are made of 75% copper and 25% nickel. These cupro-nickel coins also contain small amounts of copper.
The one and two-dollar coins, also known as "gold" coins, were introduced in the 1980s and are composed of 2% nickel, 6% aluminium, and 92% copper. The two-dollar coin is smaller in diameter than the one-dollar coin but is slightly thicker. The one and two-cent coins, which were discontinued in 1992, were traditionally called "copper" coins, although they were made of an alloy of 97% copper, 2.5% zinc, and 0.5% tin.
Australian coins have a medallic orientation, similar to most other Commonwealth coins, Japanese yen coins, and euro coins. They are also designed with unique features to be distinguishable by touch for individuals with impaired vision. For example, the 50-cent coin has 12 flat sides around its edge, distinguishing it from the 20-cent coin, which used to be circular.
In addition to the standard coins, Australia also has collectible coins, which are legal tender and can be used as currency or converted into standard coinage at banks. These collectible coins include aluminium bronze, silver, gold, and bi-metal coins.
