2. Origin of the Australian One Dollar Coin

The $1 coin was first introduced on 14 May 1984 by the Royal Australian Mint. It replaced the one dollar banknote, which had a shorter lifespan and was more costly to maintain. The idea behind the change was to provide a more durable, long-lasting form of currency for everyday transactions.

4. Composition and Minting

Originally made of an aluminum-bronze alloy, the $1 coin is 25 mm in diameter and weighs 9.0 grams. It features an interrupted milled edge, making it harder to counterfeit.
