There is a small outline of the roof supports. I would not call this a floating roof variety and I'd say it's worth around a Quarter at best. The FG initials are present but also weakened. Welcome to CT.
There really isn't a set value for a Floating Roof Cent. It's only what a collector is willing to pay for one. I have seen many true Floating Roof issues over the years so I can say they are plentiful and not rare. But If I were to put a value.. No more than $1.00 or $2.00 You won't get rich with that certain type of issue.
@Marie909 First, welcome to the neighborhood! You can include me in the group that does not believe the "floating roof" carries any premium. Chris
I rummaged around in some cents and came up with this one. I only looked at a few coins. I bet I have a few more if I wanted to look for them.
