the claims made by the US government‚ regarding the spectrophotometric analysis of a copper penny hold true. Before 1982‚ the Lincoln cent contained 95% copper and 5% various mixtures of zinc and tin. As the cost of copper increased‚ the cost to produce the penny was more than the actual face value of the penny. This caused the US government to change the composition of the penny. The pennies we know today consist of a copper coating‚ which contains mostly zinc metal‚ and has a 2.5% mass. The contents
