fortcollins Pillar of the Community United States 3671 Posts	Posted 09/07/2019 8:23 pm Zinc cent blanks are manufactured privately, by Jarden Zinc. Jarden uses a proprietary process for plating, resulting in double thickness on the edge and an extremely thin layer on the faces of the blanks. The blanks are rub through an upsetting mill, but are not annealed before striking. The Denver mint did not strike any foreign coins between the Liberian coinage ending in 1975 and the date of your coin. Reverse plating is a standard middle school chemistry class experiment. It can be done with a potato battery, simply by reversing the anode and cathode during the process. Your coin appears to be either a reverse plating experiment or the victim of environmental damage (such as a Katrina coin or a Harvey coin, immersed in toxic wastewater).

Sarge50 Pillar of the Community United States 768 Posts	Posted 09/07/2019 8:43 pm Just a thought.....isn't Zinc Supported to stick to a Magnet? I put a magnet to this coin and it DOES NOT stick to it? Could the stripping experiment, or environmentally damage have demagnetized it? Thanks for your responses? Report this Post to the Staff
