Assuming you have a penny dated after 1982, it's actually made out of zinc -- it's just missing its outer copper layer. It has a retail value of a couple of dollars.
If it's dated 1943, you have a standard "wartime" cent struck (btw, not "stamped") in steel to conserve copper for the war effort. Unless the coin is in like-new condition, it'll be worth 50¢ to $1.
It is worth a nickel
A 1976 nickel is worth face value, which is five cents. It is not worth more due to its age or any other factors.
There is no statistical number for how much nickel is in the earth. However, scientists believe that nickel is the 2nd most abundant element in the earth's core.
It's worth about 12.5 million dollars.
Because he is fat
A date is needed, also an explanation of the term aerial misstruck.
The penny is worth 1 cent, unless it's misstruck or something.
A Buffalo Nickel stamped on a penny is worth $800.00. A Jefferson Nickel stamped on a ZN penny is worth $70.00. A Jefferson Nickel stamped on a CU penny is worth $60.00.
The silver nickels are worth about $1.50 in scrap silver if circulated or up to about $3-4 if in excellent condition. The steel penny is worth about 2-3 cents if circulated and up to a buck or two if in brilliant uncirculated.
The 1944 steel penny is worth between $75,000 and $110,000. This steel penny was minted by mistake and there were not a lot of them around.
A 1943 steel penny with no mintmark can be worth $.35 - $1.50
A 1943 steel penny is worth just that 1cent.
Steel cents were only made in 1943. Your coin is plated. It is considered an altered coin and is worth a penny.
Pennies in 1941 were mostly copper, not nickel, and they're worth about 5 cents.
It depends on what you call "misstruck" post new question with more details.
Since there were none minted from steel that year, I would have to assume it is either plated (with silver, zinc, or nickel) which has no collector value, or it was minted on a foreign planchet, which would be worth about $50 You can verify that it is not steel by trying to stick it to a magnet. If it does not stick, then it is not steel.
Around 5 cents.
