[QUOTE="desertgem, post: 3534661, member: 15199"]A copper alloy cent is 3.11 Plus/or minus 0.13grams so 2.98grams to 3.24 grams ( you have to have a scale which will weigh the 2 decimal places) The copper coated zinc cents is 2.50 plus or minus 0.10 grams or 2.40-2.60 grams. In between 2.60 - 2.98 , you might need specialized instruments such as XRF to test, and 99.99% will not be what a person wants. Put it away for 10 years and your cell phone may have a free app. :) Jim[/QUOTE]
