Introduced in 1966, the 5-cent coin is the lowest-denomination coin in Australia
Twenty 5-cent coins make up an Australian dollar. The 5-cent coin is the lowest-denomination coin in Australia and was introduced on February 14, 1966, replacing the pre-decimal sixpence. In its first year, 30 million coins were struck at the British Royal Mint in London, and another 45.4 million were produced at the Royal Australian Mint in Canberra. Since then, with the exception of 1981, the coin has been produced exclusively in Canberra.
The 5-cent coin was introduced alongside decimal currency in Australia. The original reverse design of the echidna on the standard circulating coins has not been changed since its introduction. The obverse design was altered in 2016 to mark the 50th anniversary of decimal currency, but the echidna design has remained constant. The only commemorative coin in this denomination was issued in 2016.
The purchasing power of the 5-cent coin has decreased due to inflation. As of 2018, it represents 0.27% of the country's minimum hourly wage for workers aged 21 or over. There has been some debate about removing the coin from circulation due to its low value and high production costs. However, there are no confirmed plans to remove it.
The Royal Australian Mint chief executive, Ross MacDiarmid, estimated that the coin would likely cease to be used sometime in the second half of the 2020s due to a drop in demand. The production cost of the coin was 12 cents in 2022, and the metal content of the 5-cent coin is worth only 2.5 cents or 50% of its face value.

One kilogram of 5c, 10c, and 20c coins is worth $17.70
The Australian five-cent coin is the lowest-denomination circulating coin of the decimal Australian dollar. It was introduced on February 14, 1966, replacing the pre-decimal sixpence. Since the withdrawal of the one-cent and two-cent coins in 1992, the five-cent coin has been the lowest-denomination coin in general circulation. Due to inflation, the purchasing power of the five-cent coin has decreased over time.
In Australia, one kilogram of any combination of 5-cent, 10-cent, and 20-cent coins is worth $17.70. This is because each of these coins has a face value of 1.77 cents per gram of mass. For example, a kilogram of fifty-cent pieces, which have a higher denomination, is worth $32.15.
While the five-cent coin is still in circulation, there has been a significant decline in demand for circulating coins in Australia over the last few years. The Royal Australian Mint has indicated that the 5-cent and 10-cent coins may eventually be phased out, allowing them to "fade away, 'naturally'".
Despite the potential for the 5-cent coin to be phased out, it continues to be a part of Australia's currency and can still be used in transactions. As such, a collection of one kilogram of 5-cent, 10-cent, and 20-cent coins can provide a notable value of $17.70. This highlights the cumulative value of these lower-denomination coins, even as higher-denomination coins, such as the fifty-cent piece, offer greater value per gram.

The 5-cent coin is worth 0.27% of Australia's minimum hourly wage for workers 21 or over
The Australian five-cent coin is the lowest-denomination coin in circulation. It was introduced on February 14, 1966, and replaced the pre-decimal sixpence. Since the one-cent and two-cent coins were withdrawn in 1992, the five-cent coin has been the lowest-denomination coin in general circulation.
Due to inflation, the purchasing power of the five-cent coin has decreased over time. As of 2018, the five-cent coin's value represented 0.27% of Australia's minimum hourly wage for workers aged 21 or over. This means that it would take 370 five-cent coins to equal the hourly minimum wage for this demographic. As of July 1, 2025, the national minimum wage in Australia is $24.95 per hour or $948 per week (based on 38 working hours).
The Fair Work Commission is responsible for reviewing and adjusting the minimum wage annually. This is significant because it represents the only guaranteed wage increase across the economy. Unions in Australia, such as the Australian Workers' Union, advocate for wage increases, while big businesses typically lobby for freezes or reductions.
The minimum wage in Australia is the lowest amount that an employee can be legally paid for their work. It is important to note that the minimum wage may be set by the award or agreement that covers an employee's industry or occupation. These awards outline specific pay rates, penalties, and allowances that may differ from the national minimum wage.

The Australian 5-cent coin is similar in size to the American 10-cent coin
The American dime, on the other hand, has been in circulation since 1796 and is made of a copper-nickel clad composition. While the Australian 5-cent coin is similar in size to the American dime, there are some distinct differences between the two coins. The Australian 5-cent coin features a depiction of an echidna on one side and the head of state, Queen Elizabeth II, on the other. The coin is produced exclusively in Canberra, except for the year 1981 when it was also produced at the Royal Mint in Llantrisant, Wales, and at the Royal Canadian Mint in Winnipeg.
The American dime, or 10-cent coin, is the smallest-denomination coin in circulation in the United States. It is worth noting that the Australian 5-cent coin is not identical in size to the American dime, but they are close enough in dimensions that it can lead to confusion between the two coins. This similarity in size has resulted in instances where people have accidentally mixed up the coins, particularly when travelling between the two countries.
The value of the two coins also plays a role in this mix-up. In Australia, if someone receives an American dime instead of an Australian 5-cent coin, they effectively gain 9 cents due to the higher value of the American coin ($0.10 USD = $0.14 AUD). This profit incentive may encourage people to intentionally pass off American dimes as Australian 5-cent coins, taking advantage of the similar sizes and colours of the coins.
To conclude, while the Australian 5-cent coin and the American 10-cent coin (dime) have different values and designs, their similar sizes can lead to mix-ups and provide opportunities for profit, particularly when exchanged in the respective countries. This highlights the unique relationship between the coinage of these two nations and the impact of currency exchange rates.

20 nickels equal $1.00
The Australian five-cent coin is the lowest-denomination coin in circulation in Australia. It was introduced on February 14, 1966, replacing the pre-decimal sixpence. Due to inflation, the purchasing power of the five-cent coin has decreased over time. As of 2018, it represented only 0.27% of the country's minimum hourly wage for workers aged 21 and over.
To answer the question of how many five-cent coins make up a dollar, we turn to basic arithmetic. Since each five-cent coin is worth 5 cents, it follows that 20 coins of this denomination would total $1.00. Therefore, 20 nickels equal $1.00.
It is worth noting that the Australian five-cent coin shares similar dimensions and colour with the American 10-cent coin or dime. This similarity has led to instances where people have profited from mixing up the two coins.
Interestingly, the 5-cent coin in Australia has the same weight-to-value ratio as the 10-cent and 20-cent coins. Specifically, one kilogram of any combination of these three denominations of coins is worth $17.70. However, this calculation assumes that each 5-cent coin weighs exactly 2.825 grams, whereas the actual weight is slightly higher at 2.83 grams.
