I am aware that there known Lincoln pennies that are classified as "floaters" and also some that have no "signature as well. What I see are 1969 and 1970 varieties primarily, however, I have come across others that are floaters and some of these are without signature as well. The examples that I have are: 1978 D, 1987 D, 1994 D, 1995, 1997, AND 1999. My question is are they an error that has value? The example that is shown is a 1969 D that is a floater and also has no signature. Suggestions are welcome, thanks.
