I agree with the Grease Filled Die for the weakness in the date. Pretty cool to see the same weakness in two different mints!
The corrosion is obviously rust, (some cleaned away on the S cent). The zinc coating was thin/wore away, allowing moisture to the underlying steel. Nice, unique, and unfortunate aspect for the 1943 War Cents.
