An investment idea

Australian 20-cent coins are made of a 75-25 copper-nickel alloy: 8.5 grams of copper to 2.8 grams of nickel. When I checked yesterday afternoon: copper was AUD 10,200 a (metric) tonne, and nickel was AUD 33,500 a tonne. By those numbers, the metal in a 20-cent coin is currently worth eighteen cents. I think I’ll go out and buy a shedload of 20-cent coins. Even if metal prices plunge, you’ll still be able to sell them for twenty cents.
