Clarification on Pennies

I have a few questions that the books I purchased do not answer.
I have a 1982-D penny with the small 8 which does not weigh 3.11g. I understand that to mean it is not an error.
What is the standard weight for the following dates: 1944;1945;1950;1958;1968;1973;1978 & 1980
I have weighed each and they vary between 3.08 and 3.15.

This is one of many questions but I am on my way out the door for work.
The Redbook is everywhere and will answer your questions regarding weight and many other questions you may have. The book might cost $10-$15 or you may obtain one from a local library. This is what you should be reading.

All of those weights are within tolerance range.
There is a tolerance for +/-. It looks like 3.11g +/-.13. So you cents are within tolerance.

Don't waste your time weighing coins. No one cares who will pay a premium. I'm not sure if anyone cares at all. Study this site and forget about the "fortune in your pocket change" videos.
Weight is usually only useful if another issue has been identified first.
As suggested above, weighing coins just for the heck of it is a huge time waster. You will spend too much time investigating coins that are slightly over or under weight.
In 1982 they had both the 95% copper alloy (3.1g) and copper plated zinc (2.5g). Both had large and small dates.
If you have a 1982 Denver small date with the copper alloy, it is a transitional error and worth decent money. One sold at Stacks Bowers for over $15K.

3.11 grams give or take
I occasionally weigh gold coins, usually due to condition, and to be sure no significant loss due to wear. I never weigh cents.... Cheers, RickO
