A few were struck in 1944 by mistake when some leftover steel blanks got mixed in with the normal bronze ones, but these are considered to be mint errors.
There are no exact records of the number of copper pennies made in 1943. It was about 40. Most pennies that year were made of steel.

The US has never made lead pennys, but if you mean the 1943 Zinc coated steel Lincoln cents, average value is 10 cents.
It depends on what year they were minted but from 1982 to date Lincoln cents are made from .975% zinc & .025% copper.

Yes. There have been exceptions granted by Congress, but all US coins are to be dated with the year they are minted.
The switch was made in 1982. Some pennies that year are copper, and others are zinc. If you can't tell the difference, then use 1981 for the last year.
J.C Pennys opened in 1902.
It may sound funny but it's wheat
The last year for wheat pennies was 1958.
Pennies do not rust because they are made of copper-plated zinc. However, the copper plating can react with certain acids and chemicals, causing them to tarnish or develop a patina over time. This is different from rust, which is the result of iron or steel reacting with oxygen and water.
