If you have two 1943 steel pennies both of white color one sticks to a magnet and the other does not what is difference there in value?

The 1943 steel penny that sticks to a magnet is a copper-plated steel cent, while the one that does not stick is a zinc-coated steel cent. The copper-plated steel cents are more valuable than the zinc-coated steel cents, and can be worth up to $100,000 in uncirculated condition. The zinc-coated steel cents are worth only a few cents each.

The reason for the difference in value is that the copper-plated steel cents were produced in error. The United States Mint had planned to produce steel pennies in 1943 due to a shortage of copper, but they accidentally plated some of the steel cents with copper instead of zinc. The copper-plated steel cents were released into circulation, but they were quickly recalled when the Mint realized its mistake.

As a result of the error, the copper-plated steel cents are now considered to be rare and valuable coins. They are especially sought-after by coin collectors, who are willing to pay a high price for them.
