Get a better scale. The weight is supposed to be 3.11 g. I imagine 3.2 g is within the tolerance of the scale. you might try grams or pennyweight to try and get an extra digit in the mass.
It's also possible that someone plated it. Hard to tell from the pictures.
Your 1982 cent was made in bronze (95% copper and 5% zinc)*, is reactive to the environment and can 'look' different depending on storage, where its traveled, etc.
1982 cents weigh either 3.11 g (bronze) or 2.5 g (copper-plated zinc).
*Some refer to an allow of only copper and zinc as brass, rather than bronze.
See http://www.doubledimes.com for a free online reference for US twenty-cent pieces
The 'color' of the cent could be either environmentally induced or it may be flash plated... that may account for the slight increase in weight.. or your scale may be off a tad. Cheers, RickO
Looks like someone cleaned it with soap then rubbed with baking soda and dropped in vinegar.
Ricko got it.
It looks plated to me, which could
account for the weight, but in any
case, it's within tolerance.
