One of my students' parents found this while doing some work on an old house downtown. It was buried about 5 feet in the ground and the house was built in the '20s.
The best I could figure out with my own research was that it was probably made between 1860 and 1960, but I figure you guys could probably get a little closer than 100 years.
I know it's a brass shotgun shell, and it says "Winchester" across the top, and "No. 12" on the bottom for the head stamp. Its almost impossible to read though because of the corrosion.
So, what do you guys think?
Sorry, I didn't realize that last one is upside down.
