Before retiring from driving truck in Feb., 2016 I had a dedicated route that started from a wiring harness producer in Warren, Ohio. From there the wire scrap went to Ft. Wayne, IN to be processed into a more manageable form. From Ft. Wayne it went to Buffalo, NY for smelting to be formed into different copper based products. Some of it was processed into copper billets/ingots, some of it was blended with zinc and other trace elements for different grades and types of brass. One of the other operations at this facility was making cartridge grade brass and the blanking/pre-form operations for cartridge cases. On a couple of different trips into this facility I noticed many Canadian pennies laying on the floor around the loading docks. The pennies always looked like they had been "beat-up". I asked about the pennies laying around and about the damaged condition, and they told me this. Canada had eliminated pennies from their currency and these were brought in to be smelted for the metal that was in them (copper coated zinc). They were de-faced to remove any monetary value and turned in scrap metal.
