What is a 1943 penny worth?

In circulated condition, a 1943 United States cent made of steel with a thin coating of zinc is worth perhaps 10 to 25 cents; in really pristine uncirculated condition, perhaps 2 to 5 dollars. If you have a 1943 United States cent made of copper (and if you do, it's probably fake because there are only a handful in existance), then you have something worth several thousand dollars.
