I used to think that all $1 and $2 coins were made of entirely gold because they are a yellowish color (they are made of mainly copper). I also thought that 5 cent, 10 cent, 20 cent and 50 cent coins were made of nothing but silver (they are actually a mixture of copper and nickel). I live in Australia by the way.
