I need a penny for an experiment of sorts, but i have never seen a penny in my life! I figure a coin made out of any of the same/similar material will work just as good, so can anyone shine a little light on what Australian coins are made of? Thanks
5c, 10c, 20c and 50c coins are 75% copper and 25% nickel$1 and $2 coins are made from aluminium bronze, which is 92% copper, 6% aluminium and 2% nickelThere was also a kind of round 50c coin for a while, which was made of 80% silver, but they took it out of circulation after the price of the silver became higher than the value of the coinThe old 1c and 2c coins were mostly copper; about 97%The rest would be zinc and a little tin.
