I have found one which weighs 2.60 g. Everything else about the coin is normal. What should I know?

Weight tolerances for US coins can be found in the Coin World Almanac.

After I read white font on a black background, I am nearly blind afterwards....

I find many Zinc cents that weigh as much as 2.7 grams on my scale.
I'm sure there are many cents that weigh even more than that due to thick planchet errors, and most likely a few that weigh considerably less than the required weight.

Slamnbass - that is a dynamite tool!

Thank you!

I found this reference also:

H.R.16032 93rd Congress (1973-1974)

Specifies the considerations and conditions upon which the Secretary may change the composition of the alloy of the one-cent piece.

FYI, I went off the CCF grid looking for any Coin World Almanac references and ran across the following on another coin forum. Posted by Condor101.

Sorry no reference to the copper plated zinc era listed after 1982, so assume its still the standard after seeing the other references here on CCF that reference to it. Thanks, Doug.

I don't know the standards used in other countries, but I have a list of the allowed tolerance for most US coins.

Small cent 1856 - 1971 was 2 grains or +/- .13 grams
Small cent 1972 - 1982 was 1.9 grains +/- .12 grams
nickels 1855 - date 3 grains +/- .19 grams
dimes 1.5 grains +/- .09 grams

quarters 3 grains +/- .19 grames (notice it is geting stricter. Weight of coin up 2.5 times, tolerance up only 2 times)

Halves 4 grains +/- .26 grams (weight up 100% tolerance up 33%)

silver dollar 6 grains +/- .39 grams (weight up 100% tolerance up 50% compared to the dime the weight is up ten times, tolerance up four times.)

Ike dollar 40% or clad 8 grains +/- .52 grams This is the only clad coin not held to the same standard as the silver versions.

Gold coins were held to much stricter tolerances especially as the weight increased.

gold dollar .25 grains +/- .02 grams

quarter eagle .25 grains +/- .02 grams weight up 150% tolerance up 0%

three dollar .25 grains +/- .02 grams still 0% increase in tolerance

half eagle .25 grains +/- .02 grams still 0% increase in tolerance

eagle .5 grains +/- .04 grains ten times the weight of the gold dollar with only a doubling of the tolerance allowance.

Double eagles .5 grains +/- .04 grams Weight doubled again with no increase in tolerance.

The information came from the Coin World Almanac 1976 edition.
Second opinions are always recommended. Rookies thoughts!
Two sides to every coin. The edge makes three.
Side Note: Sometimes I feel like a nut, sometimes I don't.
