Need some help possibly identifying the attached photos. Guy I know claims they are civil war hand grenades. Seem to look similar to the 2.5 Selma hand grenades. They were found in north Alabama. Just trying to see if any professionals have any input on what they could be. If they are even civil war related. If they are, they are rare. Claims he found 8 total approximately 2 to 3 foot deep in the ground. Appreciate any input. P. S. I’m new to the site. Maybe I loaded the photos correctly.
