What is the copper penny worth?

Answer 1

One cent.

A More Complete Response:
It's not possible to give a specific answer. US cents made out of copper, copper-bronze, or copper-nickel were struck at 3 different mints over almost 200 years - 1793 to 1982 with only a few exceptions, e.g. 1943.

Please post a new question with the coin's date. If it's a Lincoln cent also indicate whether there's an S or D under the date, or no letter.
