Why would anyone in there right mind zinc plate a COPPER 43-S ? And yes see if attracts strongly to a magnet .  |

It's slightly heavier than a standard steel wheat. Rust, I think can be debated. Look at the reverse. There is a clean separation there. I'm no expert. Just hopeful. Very hopeful.   |

And it sticks to a magnet. But what if it just an outer layer that sticks?

You should get another 1943 steel cent and put it up to the magnet. If this one was a real 1943 copper it wouldn't stick has strongly as the '43 steel.

atmospheric discoloration - aka rust.

Pretty sure it is a regular 1943 s.

If you run your finger very lightly over the edges of the irregular area in "Liberty", can you sense which area is higher - the spot, or the field around it?  |

It is not the outer layer of a steel cent that sticks to a magnet, it's the steel core. Zinc is not attracted to a magnet. The only substances which you are likely to find in a coin that stick to magnets are nickel and iron (steel). So if it sticks to a magnet, it's a normal steel cent and there really aren't any other options. Theoretically, if you did find a steel-plated-copper cent it would not be a unique mint error, it would be a counterfeit.
The brown colour you are seeing breaking through the zinc layer on this coin is just the rusty steel underneath.

Looks like a steel cent where a drop of a solution with copper suspended in it attached to the substrate. Maybe done with a 9 volt battery. But it doesn't look to be the reverse case.

Not copper, just stained/rusted.

There's another possibility. A drop of copper sulfate solution on a zinc-coated cent will initiate a displacement reaction since zinc metal is above copper in the activity series.
Zn(s) + CuSO4(aq) --> ZnSO4(aq) + Cu(s)
The result would be copper plating consistent with the pictures, at least on the obverse. Someone want to try it?

Tried it. That was my reasoning above. I recall using copper sulfate and/ or a cupric amino solution eons ago. Might have used a battery and an alligator clip too. I'm reasonably sure the subject coin was exposed to the solution and bonded.
