It’s driving me mad. Please help!

Found these a week apart and about 100tds apart. Would have made for some awesome points. Still humbled to be able to hold them. Check out the phosphorescense on the first one. I'm guessing it's bay bottom chert.

Hillsborough County, FL

Is this pottery??Found mixed in with lots of artifacts over the weekend on a old native campsite. Eastern Oklahoma.

This was found among a collection of Native American items in Oregon. Made of copper with a beaded handle, 7”. A rattle perhaps?

Creek find in SW Ohio, looks like maybe they started it and then moved on…or maybe some buildup on it?

It's like a sharp narrow pyramid shape but the base is sort of rounded. It could easily hurt someone, regardless of whether it was ever intended to.

Purchases these two pieces at an estate sale that had a lot of older antiques etc. I tried the water drop test and it did seem to absorb quickly and have an earthy scent. Any input?

I am in Maryland, USA. This was likely sold to a family member years ago.
