Killer finds..can I ask where you found them...just the state..it will affect the probable age.
They look to be either Spanish or French conicals....leaning towards French...the Spanish were usually a bit larger.
They would have most likely been supplied to the Native Americans who were allies to one of those two groups in an effort to wage war against an opposing group..Mabey British.
If you have already I.D.'d the button that may help.
They were found in northern Ohio there was a fort here in the war of 1812 the Indians didn't. Leave here till 1845 the button is cival war button I think
I'm pretty sure the points predate the button..if it is civil war...you did say there was a fort in 1812 though.
Forts were usually built in areas that were "good ground" for many of the same reasons the Natives utilized the same areas long before any European arrival.
I would probably use your local historical society website to get an in depth understanding of that site.... I've done the same with Second Seminole war forts here in Florida 1835-1842
I didn't find these at the fort. I found them on a bluff above a river there was native activity here till around 1845 when the government shipped them Kansas
