Earle42 Bedrock of the Community United States 10038 Posts	Posted 10/07/2018 8:31 pm From the article: Quote: As part of the coin's authentication process, ANACS commissioned a spectrographic analysis to determine its complete metallic composition. The results determined the coin is 93.3556 percent copper, .009 percent silver, 6.5138 zinc, 0.0434 percent nickel and 0.772 percent iron. The standard composition should have been 95 percent copper and 5 percent zinc. How much squash could a Sasquatch squash if a Sasquatch would squash squash?

Conder101 Bedrock of the Community United States 17884 Posts	Posted 10/09/2018 12:06 pm Take just about any sample of metal and you are going to find trace elements in it. The silver and nickel levels don't strike me as odd, the iron is a little high. Probably at least some of the copper the mint uses comes from recycled sources. At some point it becomes more expensive to refine out those traces than it is worth. The odd percentages of copper and zinc are because of the difficulty of making bronze or brass with an exact composition. Zinc boils and vaporizes off at a lower temperature than copper melts. So you have to dissolve copper into molten zinc. But eventually you reach a point of saturation where you can't dissolve any more and you have to start raising the temperature to get the copper to melt into it. But then you start losing zinc. So normally you have to start with an excess of zinc and then get all the copper into the melt before the zinc loss reduces the zinc below the alloy mix you are shooting for.
