What's Inside an American Penny? Exploring Copper Content Through the Years #CoinCollector The composition of American pennies has changed over the years. Prior to 1982, pennies were made of 95% copper and 5% zinc. Due to rising copper prices, from mid-1982 onward, pennies have been primarily made of zinc (97.5%) with a thin copper plating (2.5%). This shift significantly reduced the amount of copper in each penny, making older pennies heavier and more valuable in terms of copper content compare

Phil Cook on Instagram: "Pure copper pennies (those minted prior to 1982) have a hidden secret: you can use them like little heaters! This works because when copper is heated, it will catalyze the oxidation of ketones (I use acetone here) which releases a lot of heat, enough to keep the penny glowing red hot as the reaction occurs on its surface! #chemistry #chemteacherphil"
