Shell or Stone? Where is it from? What conditions was it found in? Creek, river, field?

It looks like a natural stone to me. I see no pecks marks, grinding, or anything that would lead me to think it was made by man.

Natural stone, all day.

 

[Fl Hunter]

Its stone, very smooth, found in southwest Fl. about 25 yds from the beach just inland on a long spit of barrier island.

Is it a potato?

That explains the polish. Years and years of being pounded by the surf will do that to stone. It's natural and not an artifact.

It looks like a natural stone to me except for what looks like recent scratch marks that are awfully evenly spaced.
Did someone use a wire brush on this?

 

[The Grim Reaper]

Gator, I figured those were part of a Fossil inclusion in the stone.

 

[GatorBoy]

That type of solidified sediment usually does not have fossils in it here

 

[GatorBoy]

It's basically beach sand
