Over Weight Steel 1943 Penny

I have a 1943 P Steel Penny that is magnetic. But after weighing this particular penny I found that it a bit heavier than the other steely's I have. Most of the Steel I have are around 2.60 to 2.70 grams, the penny in questions is closer to the weight of a copper, 3.00 grams. Any ideas?

Tare?

 

How about checking the scale. What does a copper penny weigh?

 

According to the red book 3.11 grams.

 

Weigh a copper penny on your scales and see what you get. Your scales may be out a little bit...

 

I just weighed a 1944 penny and it weighed only .02 grams off

 

If it is a bright and shiny, it sounds to me like someone replated it.

 

Look, I'm an analytical chemist with over 15 years of experience with 2 different tared out scales, please try to comment on the coin instead of the scale

 

it isn't replated

 

You win

You win. It's dense. Got a Geiger Counter?

 

not replated, seen a hundred of these. Nice dull finish. I'll try and get a pic in here after the LSU game

 

checked it, not a nuclear penny

 

Averaged weight of ten wheaties at 3.08 grams, scale is on.

 

coin diameter the same? could have been some shaving stuck on the planchet and struck back into the coin? just guesses!

 

With tolerances, the '43 zinc coated steel could weigh a max of 2.88 grams and be within specs.

 

I actually have a 1943 P steel penny that weighs 3 grams. It is thicker than my other steel Pennies as well. Still magnetic though.

 

I have one also.It looks like Shiney steel.Sticks to magnet,but weights 3.o6g...Has me baffled...I was thinking maybe replated..
