Australian coins are the currency used in Australia, featuring a range of denominations from 5 cents to $2. Each coin has unique designs that represent various aspects of Australian culture and history, such as native animals and notable figures. The coins are made from different metals, with the lower denominations typically made of copper and nickel, while the higher denominations often use a combination of metals for durability. The Royal Australian Mint produces these coins, ensuring they meet specific standards for quality and design. Coins are widely used for everyday transactions, making them an essential part of the Australian economy.
