Wow it has gone up in price! Scale in USD / Tonne. Wonder what will happen when the US 1 cent coin has more scrap value than monetary value? (afaik 97.5% Zn 2.5% Cu) and 2.5g
Not just copper but nearly all non-ferrous metals.
The amount of copper in a 1 c coin is very small, as it is essentially zinc with copper-laminated faces. I think the copper is about 70 µm thick. However, the total cost of making a 1 c coin is currently about 1.5c!!! Time for it to be scrapped, I guess. A penny for your thoughts.
British pennies turned steel about 10 years ago I think for this very reason. There are still quite a few copper ones in circulation though - a magnet can tell the difference easily enough
Apparently this is also causing a bit of a nightmare for telcos, especially in sparse countries - people are nicking the copper telephone wires to melt down...
NEW YORK (Reuters) - Shares in metals miners fell broadly in pre-market trading on Monday as recent record-driving bullishness weakened, and copper and gold declined sharply.
"Everybody has got a bit jumpy," said Mark Mathias, managing director of Dawnay Day Quantum hedge fund. "We've seen very sharp rises over the last couple of months on equities and commodities, so it's no surprise it's being marked down a bit."
Industrial and precious metals fell as bullish sentiment faltered. Copper, which hit a record high last week, fell to $7700/7900 a tonne, down 8.8 percent from Friday's close.
Gold <XAU=> slid as low as $687.60 an ounce, down 3.7 percent from $714.10/715.10 Friday in New York. The metal reached a 26-year high last week.
