What is the max weight the the us mint allows for a 1962 penny it weighs 3.29 grams seems a little heavy does anyone have a true factual answer if so please respond thank you
It's a little heavy. The scale could be off, or, the coin could be slightly thicker and heavier than normal. If you weigh a number of copper cents that all come in around 3.1 and this one still weighs 3.29, then it's not the scale and it is heavy.
