This is Off Topic. So delete it now or do not complain!

Most of you know that I am totally blind. Recently I got questioned about my
correctness in the weight I stated for the 1909 through 1958 Lincoln Wheat
Cent. I said it was 4.11 grams. It was changed in 1962 after it became the
Lincoln Memorial Cent in 1959. The Copper remained at 95%, but the mixtures
of Tin and Zinc reduced the weight to 3.04 grams. Then in 1982 the Mint
reduced the overall weight down to 2.5 grams by reducing the Copper content
from 95% to 2.4% In all practicality, the cent was 97.6% Tin and Zinc, with
a Copper plate of 2.4%

The only other change that I am aware of came in 2009. This was the 100th. 
anniversary of the Lincoln Cent. The United States Mint released four new
Copper Cents that year. All of which show a different graphic relief on the
obverse and the same pattern on the reverse.

What was the weight on the Lincoln Copper cent in 1909-1958, 1962 and 1982? 
Thank you!
