1943 zinc plated copper cent!!

It looks like at normal 1943 steel cent, except at the points of heavy wear that go through the zinc plating and nornally show the steel core, this one shows that copper in underneath!! A rare copper 1943 cent, except zinc plated like the normal steel cents were!


Or maybe it's not, maybe I did this? Who is smart enough to know how this was possibly done?

Scrub a dirty (not corroded) Zinc coated Steel with Easy-Off BAM using a toothbrush and the Zinc will turn to a Copper tone!


Like rlm said, check the coin with a magnet! I check every 1943 Steel Cent that I get with a magnet just because of the very scenario that you are talking about (a Copper Cent coated with Zinc).

When iron is submerged in Copper(II) Sulfate the iron will dissolve and then be replaced with copper metal.

Copper sulfate goes by the name of septic system Root Kill at the hardware store. Speaking of science... this months Popular science say that steel wool is flamable and will light with a match, but what they don't tell you is that it will ignite with the touch of a 9 volt battery. It's so cool!!!

Try it in an oxygen rich atmosphere sometime. You will be amazed how fast it burns.

No. I mean 50% + oxygen. 100% is better. It nearly explodes.
