what kind of chestnuts????

I'm visiting my folks in Virginia (Charlottesville)and my niece and nephew are throwing these things at each other. I know we used to call them ITCHY BALLS but I don't think that's the latin name haha. What are these ? I think they're some type of chestnut...?? Not sure what zone, it's right by the Blue Ridge Mountains. thanks!
