In 1946, after the war was over, the Mint resumed the traditional five cent coin composition of copper and nickel, which is still used today.Copper: introduction to the chemical element, · The remaining ore is then heated in a huge furnace called a smelter, which burns off some of the remaining impurities and leaves a material called copper matte, which is at least 50 percent copper. A second heating process follows in which the copper matte is heated with silica and air to remove more waste, leaving a very refined material called blister copper that can be over 97 percent pure.Coin Production | . Mint, · Copper coins, such as the penny, started as pure copper, but rising copper prices led to changes in composition. In 1857, the Mint added nickel to the copper, but switched to tin and zinc in 1864.
