I have a crap ton load of steel pennies and this is the only one that weighs this does anyone know why I'm at a loss as to why
Have u try to test if it stick to the magnet yet? It does look like someone plating it with some sort IMO.
Then, I'm pretty sure it was plating or someone spray paint it, and those add it extra weight on your coin. IMO
I don't know what a ton of them is, but a scale with one digit after the decimal rounds off the final digit, so from 2.5 up , it would round to 3.0 , and the steel cent is 2.50+/- .13, so as heavy as 2.63 ( which would indicate 3.0) would still be in range. Scales now in the 0.001 range are not too expensive such as https://www.amazon.com/dp/B075Q44TC9/ref=psdc_678508011_t3_B0012TDNAM and they have a calibration weight which should be done if you move it around.

It's just kind of weird that none of the other steel cents I have weigh 3.0 all others are 2.5 to 2.7 that's the only one and I will invest in a better scale
Good idea, but remember the weight tolerances are based by the government standards on newly minted, uncirculated sample of coins. Wear and damage will tend to reduce and corrosion and dirt and grime will increase, the weight of a coin. Jim
Could be a thicker planchet. The steelies are supposed to weigh 2.7 If your scale is not accurate, wait to get a better one before worrying about it.
It was wartime emergency issue. Sheet steel was catch as catch can, even the mint. Tolerances were ignored. I think you have a thick planchet.
Nope, if it shows one place after the decimal it won't round up to 3.0 until it weighs at least 2.95 grams. A 2.63 would round to 2.6 not 3.0
