What is the value of a 1964 penny that has a fingerprint actually stamped into the coin?

It's worth a whole cent. The fingerprint isn't stamped in but was etched when someone handled it with dirty fingers. Over time, the oils from your skin will react with the metal in the coin, actually eating into the surface of the coin, which may make it look like the fingerprint was stamped into the coin.
