That's a gas bubble formed between the zinc core and the copper. Just damage. Worth 1 cent.

What you really should be asking if it's an error or not
That is Zinc Rot.. not an error and worth only 1C

Also.. the correct term is Doubled Die not Double. Big difference

quote - "Note that the proper terminology for this occurrence includes the letter 'd' at the end of the first word, hence "doubled die". The term "double die" without the first word ending in 'd' is not proper numismatic terminology" closed quote

 

You keep this at the ready, don't you?

 

Just a note but most of the coins you have been posting are within the new zinc age of cents. From 1982 to date there has been a problem with these coins showing what we call "rot" or bubbles. And it does not take long, once they enter into circulation for them to show signs of deterioration. It is a very thin film of copper that separates these from the zinc core.
