They are very common. I see them often when going through nickels. Usually you see them on 1960 nickels and they call them bar 0. All they are is a die chip which I personally wouldn't even call an error yet. Instead I think of it as a die state. But sellers give a nickname to it and all of a sudden they can get money for them.
I have seen this on some I am searching and didn't think it was anything. 
Would they be worth saving?
