(Before 1962 the 5% was a mixture of tin and zinc.)

Just for color. I never tried heating a Zincoln too far with my mini-torch. I know a light heating just makes the copper plating change colors. Any 95% copper cent will turn silver with enough heat!

Terra Branford New Member United States 35 Posts	Posted 04/06/2018 04:11 am I managed to turn a 1975 penny goldish colored by soaking it in a water/white vinegar/salt/baking soda/ solution while cleaning it with a rag. I came out shiny, clean and gold with kinda pretty clouds of layered amber colors. Report this Post to the Staff
