they only made steel pennies in 1943, and only a few accidentally in 1944. the only answer is that someone purposely removed the outer layer of the penny, or it could be an off-metal error coin. To see if it is an error, you should take it to a coin dealer to look at
The letter D is the mint mark for Denver.
If it's magnetic it could be: A) Plated. Worth only 1 cent B) An off-metal strike made on a blank intended for a foreign coin. Value unknown but certainly a lot more than a penny. You'd need to have it examined in person to determine which.
volume of the billet * density of d material i.e for steel density is aprox 7.8*10^-6 . volume * 7.8*10^-6.
The same way on all Lincoln cents - look under the date for the letter. No mint mark letter = the coin was struck at the Philadelphia Mint D = Denver Mint S = San Francisco Mint
You look up the density of steel, then calculate the volume of the rod, then multiply the density by the volume to find the mass of the rod. To find the weight of the rod, you multiply it's mass by gravataional acceleration.The rod has a cross sectional area of Pi x (0.008 / 2)2 m2Volume of the rod = 1 x 5.027x10-5Steel has a density of approx. 7850 kg/m3.Mass = Density x VolumeMass = 7850 x 5.027x10-5Mass = 0.395 kgWeight = 0.398 x 9.81Weight = 3.871 Newtons
There's no such thing.
1943 was the only year for steel cents
Check that coin again. There's no such thing as a 1942 steel cent.
Value for average steel Lincoln's is 5 to 10 cents
Value for average steel Lincoln cents is 5 to 10 cents.
what is the value of 1945d penny
Steel cents were only struck in 1943. All 1942 cents were made of bronze. A bronze cent will not stick to a magnet; a steel one will.
The letter D is the mint mark for Denver.
Lincoln head 1927 D penny
Steel pennies were only made in 1943, during World War II. All 1969 US cents were struck in bronze. Your penny is almost certainly plated for use in jewelry or something similar. It's considered to be an altered coin and has no added value.
About 1.50
The die was filled with grease or crud and caused the "D" mintmark to fail to strike up. This is a common error and adds no value.
