Interesting, I'm anxious to see what the experts say. Cool coin.

I don't think it lamination....whatever it is it doesn't go over or through the wheat stalk...it stops before it. This makes me believe it is something on the coin. I am far from an expert but this is my gut feeling.

The 1943 cent was made with "zinc coated steel" planchets. I wonder if this coin has a partially coated reverse.

I think this is PMD from a chemical exposure. |

It could simply be some glue residue on the coin

If chemical exposure, why are none of the devises affected? I would expect glue to discolor in some way after over 60 years but again, what do I know.

I'm not saying it IS glue I'm saying it could be glue, It certainly looks like it from your photo's. A simple soak in acetone will test this out. If it is glue the acetone should soften and remove it. |

hum, I was not saying that you were completely wrong, you may be right, I was just putting an idea out there of what I was thinking. Time to break out the acetone and find out.

I am unsure as to how it could be lamination. I did not think the steel cents were made with thin layers pressed together like coppers were.

After reading on google for 20 minutes, I believe I have found a similar example of what I have here. Nothing more than zinc erosion. I found a related story here with pics towards the bottom of the post - http://www.cointalk.com/t198447/ |

The zinc coating on these cents was very thin and quickly wore off. Another contributing factor to this quick wear was that the Mint plated the cents BEFORE they were punched out of the metal strip. In other words, the whole flat pieces of steel were plated on both sides with zinc, and then the round penny-shaped blanks were punched out, leaving the edges of the blanks unplated. Because low-carbon (low-grade) steel was used, it was prone to rusting easily. Once the edges starting degrading, the zinc coating soon followed, although it wouldn't have lasted long in any case in circulation.
