Weight tolerances for a Type 2 cent planchet

Some years ago I obtained a Type 2 cent planchet but do not recall if
copper or zinc. It weighs 2.68 grams which seems a bit heavy for the
zinc but well below the 3.11 grams of the copper cents. Does anyone
know the zinc cent tolerances?
The Red Book states the zinc cent weight at 2.50 grams, meaning the
2.68 grams noted here is about 7 percent heavy.

I'm not sure, but I have the same question. I have an 1983 cent that weighs 2.80g, so I'll be interested to hear what is considered within reasonable tolerance.
Copper Cents: 3.1 grams or 48 grains, with an official tolerance of .13 grams or 2 grains
Zinc Cents: 2.5 grams or 38.58 grains, with an official tolerance of .10 grams or 1.54 grains

The answer is appreciated. It would therefore appear that the 2.68
gram specimen as well as the 2.80 gram piece noted by ShadyDave
are both outside normal tolerances. I have to wonder how common
this is.
I'd say fairly common, and not significant, imo.

I would also say, that you might check your scale... sometimes the calibration is off on these units. Cheers, RickO
