I'd appreciate any insights you can provide. I found a 1943 penny that looks like it's copper or bronze. It does not look like your typical grey 1943 steel penny, of which I have several. I used a magnet, and the coin is definitely steel, but its color is just like a red or brown penny. Any thoughts as to how it got this color? Any other possibilities. Sorry, I don't have capability of taking/posting picture. Thank you.
