Got cut off. What could be the reason I have a 1964 Lincoln Cent that weighs 2.84g when all the other coins I weigh are almost spot on 3.11? There seems to be no filing or any signs of tampering for that matter. Any suggestions?

I have a caliper somewhere. Been a while since it has been used. So far out of all the pre 1982 coins I have weighed he has been the only one to stand out

This is a standard chart feel free to copy this for future reference. The standard for this year is 3.111> 3.240. <2.980 on the low end, Circulation wear and PMD will contribute for weight loss of coins. Your`s is a whopping .14 under the lower of the standard, this is a very normal difference given how accurate your scale my be, it doesn't go to .000 out ? Just a normal old cent that went to Weight Watchers

Yes, in my opinion, just simply a slightly underweight planchet, nothing too far off. It's aged as DT stated. Treat it as just another cent. The mint wasn't perfect making these planchets back then. Understanding how all this was done would answer a lot of the questions. Especially when you see the huge rolls of material sheets used to make coinage.

Some of these questions, Google has the answer too. All it takes is a little effort to find the answer.
