I was going through wheat pennies i found a while back searching penny rolls. I always use a magnet to check for the top 1943 copper coated steel penny. But only one odd penny was attracted to a magnet, a 1936 penny. attached is front ,back ,and photo of it on a magnet. Any help please...
Looks fine to me. Can you post a picture of the Cent actually getting picked up by your magnet? Maybe by its edge under the magnet. Also. Keep the magnet away from your computer. It could damage the screen.
Maybe it was coated in buckyballs... http://blogs.discovermagazine.com/d-brief/2015/08/05/copper-magnetic/
Copper cents weigh 3.1g (3.11) and there is no coating. What's magnetic? Nickel, iron, steel, cadmium? Copper cents are 95% copper and 5% tin and zinc. Nothing magnetic could be in high enough quantities (if at all) in a copper alloy used for cents in 1936. I will guess there is some adhesive on the coin sticking it to the magnet.
Could be a bit of steel (wire or nail fragment, etc.) embedded in the planchet. Would take an industrial x-ray unit to see it. Cal
That's kind of what I'm thinking. The magnet shown looks to be out of a hard drive, and those are quite strong.
Interesting. Tell and show us more. What does it look like, what's the diameter, what's the weight? Cal
Use the corner/edge of the magnet and check to see if the coin is magnetic equally everywhere or if it is localized.
